CBMPP Explanation

This ALDOT Construction Best Management Practices Plan (CBMPP) is intended to satisfy the requirements of the Alabama

Department of Environmental Management (ADEM) Administrative Code and the National Pollutant Discharge Elimination

System (NPDES) Construction General Permit.

This CBMPP is also a means to gather and communicate environmental concerns, commitments, and contract requirements

to ALDOT design and construction personnel as well as Contractors.

This document, all referenced or attached documents, and those posted on the Electronic CBMPP webpage together

constitute the CBMPP for this project.

This CBMPP is provided to ALDOT Contractors prior to project letting.

The CBMPP is comprised of two main components; a Design Component and an Operational Component.

The Design Component is created and updated during the planning and design phase by ALDOT and/or consultant design

personnel. The Design Qualified Credentialed Professional (QCP) certifies the Design Component of the CBMPP as having

addressed all known environmental concerns, and that these concerns have been addressed in the project design.

The Operational Component is created and updated during the construction phase by ALDOT project personnel and

contractor personnel. The Operational Qualified Credentialed Professional (QCP) certifies that the Design Component will be

adhered to as closely as possible, and that the Operational Component will be created, updated, and adhered to during

construction of the project.

This CBMPP is to be maintained at the Project Office during active construction on the project and retained with the project

records after project completion. The CBMPP is to be made available to all project staff including all Contractors, ALDOT staff,

and Regulators.

PrefaceSoil surveys contain information that affects land use planning in survey areas. Theyhighlight soil limitations that affect various land uses and provide information aboutthe properties of the soils in the survey areas. Soil surveys are designed for manydifferent users, including farmers, ranchers, foresters, agronomists, urban planners,community officials, engineers, developers, builders, and home buyers. Also,conservationists, teachers, students, and specialists in recreation, waste disposal,and pollution control can use the surveys to help them understand, protect, or enhancethe environment.

Various land use regulations of Federal, State, and local governments may imposespecial restrictions on land use or land treatment. Soil surveys identify soil propertiesthat are used in making various land use or land treatment decisions. The informationis intended to help the land users identify and reduce the effects of soil limitations onvarious land uses. The landowner or user is responsible for identifying and complyingwith existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider areaplanning, onsite investigation is needed to supplement this information in some cases.Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certainconservation and engineering applications. For more detailed information, contactyour local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contact/state_offices/).

Great differences in soil properties can occur within short distances. Some soils areseasonally wet or subject to flooding. Some are too unstable to be used as afoundation for buildings or roads. Clayey or wet soils are poorly suited to use as septictank absorption fields. A high water table makes a soil poorly suited to basements orunderground installations.

The National Cooperative Soil Survey is a joint effort of the United States Departmentof Agriculture and other Federal agencies, State agencies including the AgriculturalExperiment Stations, and local agencies. The Natural Resources ConservationService (NRCS) has leadership for the Federal part of the National Cooperative SoilSurvey.

Information about soils is updated periodically. Updated information is availablethrough the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The SoilData Mart is the data storage site for the official soil survey information.

How Soil Surveys Are MadeSoil surveys are made to provide information about the soils and miscellaneous areasin a specific area. They include a description of the soils and miscellaneous areas andtheir location on the landscape and tables that show soil properties and limitationsaffecting various uses. Soil scientists observed the steepness, length, and shape ofthe slopes; the general pattern of drainage; the kinds of crops and native plants; andthe kinds of bedrock. They observed and described many soil profiles. A soil profile isthe sequence of natural layers, or horizons, in a soil. The profile extends from thesurface down into the unconsolidated material in which the soil formed or from thesurface down to bedrock. The unconsolidated material is devoid of roots and otherliving organisms and has not been changed by other biological activity.

Currently, soils are mapped according to the boundaries of major land resource areas(MLRAs). MLRAs are geographically associated land resource units that sharecommon characteristics related to physiography, geology, climate, water resources,soils, biological resources, and land uses (USDA, 2006). Soil survey areas typicallyconsist of parts of one or more MLRA.

The soils and miscellaneous areas in a survey area occur in an orderly pattern that isrelated to the geology, landforms, relief, climate, and natural vegetation of the area.Each kind of soil and miscellaneous area is associated with a particular kind oflandform or with a segment of the landform. By observing the soils and miscellaneousareas in the survey area and relating their position to specific segments of thelandform, a soil scientist develops a concept, or model, of how they were formed. Thus,during mapping, this model enables the soil scientist to predict with a considerabledegree of accuracy the kind of soil or miscellaneous area at a specific location on thelandscape.

Commonly, individual soils on the landscape merge into one another as theircharacteristics gradually change. To construct an accurate soil map, however, soilscientists must determine the boundaries between the soils. They can observe onlya limited number of soil profiles. Nevertheless, these observations, supplemented byan understanding of the soil-vegetation-landscape relationship, are sufficient to verifypredictions of the kinds of soil in an area and to determine the boundaries.

Soil scientists recorded the characteristics of the soil profiles that they studied. Theynoted soil color, texture, size and shape of soil aggregates, kind and amount of rockfragments, distribution of plant roots, reaction, and other features that enable them toidentify soils. After describing the soils in the survey area and determining theirproperties, the soil scientists assigned the soils to taxonomic classes (units).Taxonomic classes are concepts. Each taxonomic class has a set of soilcharacteristics with precisely defined limits. The classes are used as a basis forcomparison to classify soils systematically. Soil taxonomy, the system of taxonomicclassification used in the United States, is based mainly on the kind and character ofsoil properties and the arrangement of horizons within the profile. After the soilscientists classified and named the soils in the survey area, they compared the

5

individual soils with similar soils in the same taxonomic class in other areas so thatthey could confirm data and assemble additional data based on experience andresearch.

The objective of soil mapping is not to delineate pure map unit components; theobjective is to separate the landscape into landforms or landform segments that havesimilar use and management requirements. Each map unit is defined by a uniquecombination of soil components and/or miscellaneous areas in predictableproportions. Some components may be highly contrasting to the other components ofthe map unit. The presence of minor components in a map unit in no way diminishesthe usefulness or accuracy of the data. The delineation of such landforms andlandform segments on the map provides sufficient information for the development ofresource plans. If intensive use of small areas is planned, onsite investigation isneeded to define and locate the soils and miscellaneous areas.

Soil scientists make many field observations in the process of producing a soil map.The frequency of observation is dependent upon several factors, including scale ofmapping, intensity of mapping, design of map units, complexity of the landscape, andexperience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specificlocations. Once the soil-landscape model is refined, a significantly smaller number ofmeasurements of individual soil properties are made and recorded. Thesemeasurements may include field measurements, such as those for color, depth tobedrock, and texture, and laboratory measurements, such as those for content ofsand, silt, clay, salt, and other components. Properties of each soil typically vary fromone point to another across the landscape.

Observations for map unit components are aggregated to develop ranges ofcharacteristics for the components. The aggregated values are presented. Directmeasurements do not exist for every property presented for every map unitcomponent. Values for some properties are estimated from combinations of otherproperties.

While a soil survey is in progress, samples of some of the soils in the area generallyare collected for laboratory analyses and for engineering tests. Soil scientists interpretthe data from these analyses and tests as well as the field-observed characteristicsand the soil properties to determine the expected behavior of the soils under differentuses. Interpretations for all of the soils are field tested through observation of the soilsin different uses and under different levels of management. Some interpretations aremodified to fit local conditions, and some new interpretations are developed to meetlocal needs. Data are assembled from other sources, such as research information,production records, and field experience of specialists. For example, data on cropyields under defined levels of management are assembled from farm records and fromfield or plot experiments on the same kinds of soil.

Predictions about soil behavior are based not only on soil properties but also on suchvariables as climate and biological activity. Soil conditions are predictable over longperiods of time, but they are not predictable from year to year. For example, soilscientists can predict with a fairly high degree of accuracy that a given soil will havea high water table within certain depths in most years, but they cannot predict that ahigh water table will always be at a specific level in the soil on a specific date.

After soil scientists located and identified the significant natural bodies of soil in thesurvey area, they drew the boundaries of these bodies on aerial photographs andidentified each as a specific map unit. Aerial photographs show trees, buildings, fields,roads, and rivers, all of which help in locating boundaries accurately.

Map Unit DescriptionsThe map units delineated on the detailed soil maps in a soil survey represent the soilsor miscellaneous areas in the survey area. The map unit descriptions, along with themaps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or moremajor kinds of soil or miscellaneous areas. A map unit is identified and namedaccording to the taxonomic classification of the dominant soils. Within a taxonomicclass there are precisely defined limits for the properties of the soils. On the landscape,however, the soils are natural phenomena, and they have the characteristic variabilityof all natural phenomena. Thus, the range of some observed properties may extendbeyond the limits defined for a taxonomic class. Areas of soils of a single taxonomicclass rarely, if ever, can be mapped without including areas of other taxonomicclasses. Consequently, every map unit is made up of the soils or miscellaneous areasfor which it is named and some minor components that belong to taxonomic classesother than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in themap unit, and thus they do not affect use and management. These are callednoncontrasting, or similar, components. They may or may not be mentioned in aparticular map unit description. Other minor components, however, have propertiesand behavioral characteristics divergent enough to affect use or to require differentmanagement. These are called contrasting, or dissimilar, components. They generallyare in small areas and could not be mapped separately because of the scale used.Some small areas of strongly contrasting soils or miscellaneous areas are identifiedby a special symbol on the maps. If included in the database for a given area, thecontrasting minor components are identified in the map unit descriptions along withsome characteristics of each. A few areas of minor components may not have beenobserved, and consequently they are not mentioned in the descriptions, especiallywhere the pattern was so complex that it was impractical to make enough observationsto identify all the soils and miscellaneous areas on the landscape.


10

The presence of minor components in a map unit in no way diminishes the usefulnessor accuracy of the data. The objective of mapping is not to delineate pure taxonomicclasses but rather to separate the landscape into landforms or landform segments thathave similar use and management requirements. The delineation of such segmentson the map provides sufficient information for the development of resource plans. Ifintensive use of small areas is planned, however, onsite investigation is needed todefine and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions. Eachdescription includes general facts about the unit and gives important soil propertiesand qualities.

Soils that have profiles that are almost alike make up a soil series. Except fordifferences in texture of the surface layer, all the soils of a series have major horizonsthat are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,degree of erosion, and other characteristics that affect their use. On the basis of suchdifferences, a soil series is divided into soil phases. Most of the areas shown on thedetailed soil maps are phases of soil series. The name of a soil phase commonlyindicates a feature that affects use or management. For example, Alpha silt loam, 0to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas.These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricatepattern or in such small areas that they cannot be shown separately on the maps. Thepattern and proportion of the soils or miscellaneous areas are somewhat similar in allareas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils ormiscellaneous areas that are shown as one unit on the maps. Because of present oranticipated uses of the map units in the survey area, it was not considered practicalor necessary to map the soils or miscellaneous areas separately. The pattern andrelative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas thatcould be mapped individually but are mapped as one unit because similarinterpretations can be made for use and management. The pattern and proportion ofthe soils or miscellaneous areas in a mapped area are not uniform. An area can bemade up of only one of the major soils or miscellaneous areas, or it can be made upof all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil materialand support little or no vegetation. Rock outcrop is an example.

III.a. Project Specific Best Management Practices

Not Applicable

ALDOT Project No. SBR-0068 (505) proposes to remove the existing bridge over the abandoned TAG railroad on SR-68 in

Leesburg, AL. The bridge will be replaced with earthen embankments. A reinforced concrete culvert along the abandoned

tracks will provide pedestrian access from one side of the highway to the other. Construction will be accomplished via a

multi-phase traffic control plan that includes building up a temporary diversion adjacent to the existing mainline.

The project site and adjacent properties shall be protected from contaminated stormwater runoff in accordance with the

project's NPDES Construction General Permit. Project site housekeeping practices, pollution control, inspections and best

management practices quality assurance shall be as outlined in ALDOT’s Standard Specifications for Highway Construction,

sections 107.21-107.24.

The project will utilize a phased approach to erosion and sediment control to minimize adverse effects of construction

stormwater runoff. Detailed project notes (sheet 2-D) are included to ensure construction activities are in conformance

with required environmental commitments. Project specific placement of structural and non-structural best management

practices for general housekeeping, soil and slope stabilization, storm drain protection and sediment barriers are included

in the plan assembly's Project Notes, Quantities and Erosion and Sediment Control Sheets (excerpts enclosed):

Sheet 2-D: See notes 309, 401, 900 & 906

Sheet 3-3-D: See pay items specific to erosion and sediment control

Sheets 24-31, as follows:

Initial Phase (Sheets 24-25): Pre-construction measures are completed as clearing begins, before any clearing and grubbing,

and includes the placement of silt fence along the toe of proposed slopes; implementation of construction entrance/exit

pads and deployment of silt fence ditch checks at existing cross drain outfalls.

Intermediate Phase (Sheets 26-29): Site specific measures during construction phase activities associated with both

diversion and mainline traffic maintenance phases are designed to minimize stormwater impacts. These measures include

continued use of coarse aggregate construction entrance/exit pads; maintenance of silt fence along the toe of proposed

slopes; placement of wattle ditch checks and rock ditch checks in existing and proposed roadside ditches; rock ditch checks

with sump excavations at primary and secondary stormwater outfalls; temporary earth berms and slope drains to convey

storm water during embankment construction; multi-phased inlet protection at inlets as construction progresses; and

temporary seeding and mulching of disturbed soils.

Final Phase (Sheets 30-31): Post construction measures are implemented as construction is completed and permanent

vegetation is established. Post construction measures proposed for this project include placement of rolled erosion control

products on 2:1 slopes to encourage permanent vegetation; sodding of roadside special ditches (reference ditch detail on

plan sheet 2B, attached); and permanent seeding and mulching of disturbed areas.

The "2019 Alabama Special and Standard Highway Drawings" will be used for details of proper installation for erosion

control items prior to soil disturbance. All BMPs shall be implemented and maintained in accordance with the "2018

Alabama Handbook for Erosion Control, Sediment Control and Stormwater Management on Construction Sites and Urban

Areas."

CONSTRUCTION BEST MANAGEMENT PRACTICES PLAN (CBMPP)

General

The ALDOT CBMPP is a document created and maintained for every ALDOT construction project that requires

construction stormwater permit coverage under the Alabama Department of Environmental Management (ADEM)

National Pollutant Discharge Elimination System (NPDES) Construction General Permit. The CBMPP is also a means

to gather and communicate other environmental concerns, commitments, and contract requirements to ALDOT

design and construction personnel as well as the Contractor. The CBMPP is a place to document environmental

compliance including site inspections, rainfall amounts, and erosion and sediment control plan modifications. For

Priority Construction Sites, the CBMPP will also contain the sampling data collected during turbidity monitoring.

For projects permitted by the Contractor, the CBMPP shall be prepared by the Contractor Qualified Credentialed

Professional (QCP) using an ADEM approved format. The Contractor’s CBMPP shall include the same concerns,

commitments, and contract requirements made as part of the preliminary CBMPP provided by ALDOT and satisfy all

of the requirements of the ADEM regulations.

A Priority Construction Site is a construction project that discharges to a waterbody which is listed on the most

recently EPA approved 303(d) list of impaired waters for turbidity, siltation, or sedimentation, any waterbody for

which a TMDL has been finalized or approved by EPA for turbidity, siltation, or sedimentation, any waterbody

assigned the Outstanding Alabama Water, Outstanding National Resource Water, or Treasured Alabama Lakes use

classification in accordance with ADEM Administrative Code, or any waterbody assigned another special designation

in accordance with ADEM Administrative Code. If a project is a Priority Construction Site it will be noted in the CBMPP

by the designer.

Design Component

The design component of the ALDOT CBMPP is created and updated during the planning and design phase by ALDOT,

and/or consultant design personnel. The Design QCP certifies the design component of the CBMPP as having

addressed all known environmental concerns, and that these concerns have been addressed in the project design.

The design component consists of three main sections: Project Information, Environmental Concerns and

Commitments, and Environmental Best Management Practices (BMPs). The Project Information section compiles

the ADEM Notice of Intent (NOI) and project quadrangle map, properties of the soil expected to be encountered,

and hydraulic information including the anticipated rainfall conditions and the minimum design storm for temporary

BMPs. The Environmental Concerns and Commitments section compiles information regarding construction

stormwater along with other environmental issues such as wetlands, priority waters, threatened and endangered

species, historical and archaeological sites, and hazardous materials. The Environmental BMPs section compiles

standard information from the ALDOT Construction Manual, ALDOT Specifications, ALDOT Standard and Special

Drawings, and project specific information.

ALDOT construction staff, including proposed construction project staff, should become involved in the design

process as early and as often as possible to provide input relevant to BMPs. This should include onsite walk through

meetings and preliminary design review meetings. Existing conditions and potential environmental concerns should

be documented in writing, with photographs and/or video, and included with the project files. The Construction

Bureau Environmental Construction Section will review the plans for projects that are Priority Construction Sites and

those projects with 20 acres or more of disturbance for the limits of exposed erodible material. During the Prebid

2.5

Meeting (if one is held) and the Onsite Stormwater Meeting, the Region/Area Stormwater Coordinator is responsible

for discussing the design component of the CBMPP and requirements of the contract related to environmental

protection and communicating all known environmental concerns related to the project.

Operational Component

The operational component of the CBMPP is created and updated during the construction phase by ALDOT project

personnel and contractor personnel. The Operational QCP (also known as the Project QCP), which is typically the

Region/Area Stormwater Coordinator, certifies that the design component will be adhered to as closely as possible,

and that the operational component will be created, updated, and adhered to during construction of the project.

The operational component consists of five sections: Contractor Submitted Components, ALDOT Inspection Reports,

Rainfall Journal, Regulatory Actions Log, and CBMPP Modifications Log. The contractor submitted components are

the Contractor’s Stormwater Management Plan and any other environmental correspondence between ALDOT and

the Contractor. The ALDOT Inspection Reports section has an ALDOT QCP CBMPP Evaluation Log and the completed

stormwater inspection reports including any required turbidity sampling data. The Rainfall Journal section includes

a chart of the locations of all rain gauges and any RainWave precipitation monitoring points and a monthly printout

of the rainfall journal from the CPMS StormWater Tracking System (SWTS) database. The Regulatory Actions Log

includes a chart of all actions by environmental regulatory agencies and all corresponding documentation. The

CBMPP Modifications Log includes a chart of all CBMPP modifications and corresponding documentation.

During the Onsite Stormwater Meeting, the Region/Area Stormwater Coordinator is responsible for communicating

the requirements of the operational component of the CBMPP to Region/Area Construction staff, ALDOT project

staff, Contractor representatives, and any Subcontractors responsible for clearing, earthwork, vegetation

establishment, or erosion and sediment control. Others at the meeting may include environmental stakeholders

including representatives of ADEM, U. S. Army Corps of Engineers, U. S. Fish and Wildlife, and others if deemed

necessary or if required by an environmental commitment. The discussion should cover scheduling and

implementation of BMPs and other measures that will be taken to ensure and document environmental compliance

with the ADEM Construction General Permit and all other environmental commitments. All of the Stormwater

Discharge Points should be visited and discussed. For Priority Construction Sites, turbidity monitoring and

construction stormwater sampling shall also be discussed.

ALDOT CONTRACTOR’S STORMWATER MANAGEMENT PLAN (SWMP)

A completed SWMP is required for all projects regardless of the type of work, funding, or regulatory permitting. For

Contractor permitted projects, the SWMP is not required if all of the information is included as part of the Contractor’s

CBMPP. The Contractor is required to use the current version of the SWMP template without any modifications to

the format of the document in order to be considered complete. The Contractor’s SWMP should be submitted to

the Region/Area Stormwater Coordinator, or to the County Engineer for County projects, prior to the

Preconstruction Conference and Onsite Stormwater Meeting. The information contained within the SWMP shall be

project specific, address all known environmental concerns and commitments, and explain how requirements of the

contract documents regarding water quality protection will be met by the Contractor. The Construction Bureau will

review the SWMP prior to approval if requested by the Region/Area. The SWMP must be sent for Construction

Bureau review if the project includes Roadway Pipe Rehabilitation or Bridge Cleaning, or if the Contractor requests

a stream or waterbody encroachment or onsite storage of fuels/chemicals. Once the SWMP is accepted it will be

added to the CBMPP and work may commence.

CONSTRUCTION STORMWATER INSPECTIONS

Construction Stormwater Inspection Forms

Detailed field conditions, observations, and other information regarding the QCI site inspections are documented in

the SWTS on Form C-34, the Stormwater Inspection Report and BMP Certification. Sediment Loss and Turbid

Discharge field conditions require that additional information about the noncompliance be documented in the SWTS

on Form C-37, the Stormwater Noncompliance Notification Report. Form C-34a is a listing of the Stormwater

Discharge and Background Points printed from the SWTS. Any errors found on the C-34a will be reported to the

Region/Area Stormwater Coordinator immediately so that a request for corrections can be sent to the Stormwater

Permit Coordinator. Turbidity monitoring results from construction stormwater sampling shall be documented in

the SWTS on Form C-38, the Stormwater Turbidity Sampling Report.

Stormwater Discharge and Background Points

The location of the Stormwater discharge and background points are selected by the Designer and entered into the

Project Data Form in CPMS. For Priority Construction Sites, these points are potential locations for construction

stormwater turbidity sampling. These points will be located and identified on the Erosion and Sediment Control

sheets of the plans as follows. Graphical examples of point identification are located in the appendix of this manual.

Additional stormwater points may be added by the Region/Area Stormwater Coordinator as needed or as requested

by ADEM.

Primary Stormwater Discharge Points shall be identified by an integer that represents the contributing drainage

area followed by a zero in the decimal place (example 25.0). These points are locations at which channelized

construction stormwater discharge or a water of the state leaves the ALDOT ROW. These points shall be

identified in the field by a wooden stake notating the identification number.

Secondary Stormwater Discharge Points shall be identified by an integer, which is the same as the associated

Primary Stormwater Discharge Point, followed by a letter in the decimal place (example 25.A). These points are

locations within the ALDOT ROW where channelized construction stormwater discharge enters into a water of

the State.

Background Points shall be identified by an integer, which is the same as the associated Primary Stormwater

Discharge Point, followed by a non-zero number in the decimal place (example 25.1). These points are locations

at which channelized stormwater flow or a water of the state enters the ALDOT ROW.

Field Conditions

Site observations, inspections, and evaluations are conducted on a periodic basis to assess the field conditions of

each individual drainage area. This begins prior to beginning work on the project and continues until the project is

accepted for maintenance. The findings will fall into one of the four following categories:

Satisfactory – The condition of the drainage area does not need any repairs or improvements. There is no

substantial visible contrast observed at any stormwater discharge point. There is no visible evidence of

substantial erosion or sediment loss. All BMPs applicable to the current phase of construction have been


http://www.dot.state.al.us/conweb/pdf/Environment/C-34.pdf






http://www.dot.state.al.us/conweb/pdf/Appendix.pdf



2.5

properly installed or applied, have been maintained and repaired as needed, and are effectively functioning as

intended. Sediment may have accumulated immediately upstream of one or more BMPs but it has not exceeded

1/3 the height or capacity of the BMPs. Any previously reported sediment deposits off site or in a water of the

state have been remediated.

Needs Improvement – The condition of the drainage area needs minor repair or improvement. There is no

substantial visible contrast observed at any stormwater discharge point. There is no visible evidence of off-site

sediment loss. Minor erosion and on-site sediment loss may be observed. BMPs applicable to the current phase

of construction may have not all been installed or applied or this may have been done improperly. BMPs may

need repair or replacement. BMPs that have been properly installed or applied may not be effectively

functioning as intended and need modification. Sediment may have accumulated immediately upstream of one

or more BMPs and it may have exceeded 1/3 the height or capacity of the BMPs. Any previously reported

sediment deposits off site or in a water of the state have not been remediated.

Turbid Discharge – The condition of the drainage area needs repair or improvement. Turbid discharge occurs

when turbid construction stormwater leaves the ALDOT ROW and may be observed as a substantial visible

contrast at one or more stormwater discharge points. Turbid discharge also occurs when turbid construction

stormwater causes an increase of more than 50 NTU in the turbidity level of a water of the state.

Sediment Loss – The condition of the drainage area needs major repair or improvement. Sediment loss occurs

when sediment or soil is transported from the project and is deposited in a location off the ALDOT ROW or

within a water of the state.

QCI Daily Observations

The ALDOT Project Qualified Credentialed Inspector (QCI) and the Contractor’s QCI shall perform individual daily

observations of each drainage area and its Stormwater Discharge Points and BMPs where the ground is disturbed.

They shall also record rainfall measurements and weather information. Documentation of observations will be noted

in the Daily Work Report. If a previously undocumented Needs Improvement, Turbid Discharge, or Sediment Loss

condition is observed, then a formal site inspection and report is required.

QCI Site Inspections

Site inspections will not be conducted outside of normal operating hours or during unsafe weather conditions. The

ALDOT Project QCI together with the Contractor’s QCI will perform a formal site inspection for the entire project

after the accumulation of ¾ inch of rainfall that occurs within 24 hours and at least once per week. Inspections

triggered by a rain event shall be initiated as soon as possible and within 24 hours of resuming work on the project.

The inspection will include an observation of each drainage area and its Stormwater Discharge Points and BMPs. All

areas of the project not undergoing active construction will be evaluated for temporary stabilization requirements.

During the inspections that follow a ¾ inch or more rain event, turbidity monitoring will be conducted on Priority

Construction Sites disturbing 10 acres or more of erodible material. The turbidity monitoring portion of the

inspection will be conducted as soon as possible. During regular weekly inspections, turbidity monitoring will be

conducted if a substantial visible contrast is observed at one or more Stormwater Discharge Points.

Documentation on the C-34 should include field conditions and corrective actions required or completed.

Stormwater Inspection Report and BMP Certifications and any Stormwater Noncompliance Notification Reports will






2.5

be entered into the SWTS. Photographic documentation of inspections is required. At least one photograph per

inspection will be uploaded to the SWTS with a clear description of the location. Reports will be closed within 48

hours of the qualifying rain event. Once a report is closed, the Project QCP will receive an email letting them know it

is ready for their review and approval. The reports will be reviewed and approved no later than 5 days after the

qualifying rain event. Once a report is approved, the Project QCP prints a copy, signs it, and obtains the second

approval signature from the Responsible Official, typically the Area Operations Engineer. Signed inspection reports

will be included in the CBMPP at the project office and a copy will be delivered to the Contractor QCI within 15 days

of the qualifying rain event. An automatic notification is sent by the SWTS to ADEM, the Construction Bureau, the

Office of Environmental Compliance, and the Area Operations Engineer for all approved inspection reports that have

cited field conditions other than Satisfactory.

For projects with permits held by the Contractor or an LPA, the reports shall be written using ADEM’s Form 23 11/11

or Form 25 11/11 (if applicable) by the Permittee’s QCI. Formal inspections shall be reported to ADEM by the

Permittee in accordance with permit requirements. Copies of all draft reports shall be provided to the Engineer no

later than 24 hours after the inspection, and copies of signed reports shall be submitted to the Engineer no later than

5 days after the inspection.

If a Needs Improvement field condition is observed, then this information will be immediately communicated to the

ALDOT Project Manager and Contractor. The Project Manager shall work with the Contractor to create a plan for

immediate corrective actions, which shall be completed prior to the next storm event but no later than 5 days after

the inspection unless prevented by unsafe weather conditions. This corrective action may require a suspension of

all other operations. Additional inspections will be performed as needed until the observed deficiency can be

documented as corrected, satisfactory, and in compliance with the ADEM permit.

If a Turbid Discharge or Sediment Loss field condition is observed, then this information shall be immediately

communicated to the Project QCP, the ALDOT Project Manager, and the Contractor. A Turbid Discharge or Sediment

Loss condition requires a verbal notification by the Project QCP to the ADEM Field Office within 24 hours of the event

and the submission of a written Stormwater Noncompliance Notification Report within 5 days of the event. The

verbal notification requirement for Turbid Discharge conditions may be waived if written approval is given by the

ADEM Field Office. The 24-hour notification will include the permit number, county, emergency contact information,

and the period of the Turbid Discharge or Sediment Loss condition. The Project QCP will confirm the duration and

frequency of any rain event of 2-year intensity or greater associated with a Turbid Discharge or Sediment Loss

condition. The rain event information (for example a 2-year 24-hour rain event) will also be included in the

noncompliance notification. The ALDOT Project Manager will work directly with the Project QCI and the Contractor

to gather additional data. The Project Manager will inform the Project QCP of the details regarding the

noncompliance. The Project QCP shall be the point of contact for any discussions with the Responsible Official,

Region/Area Stormwater Coordinator, property owners, environmental groups, or regulatory agencies. The

Region/Area Stormwater Coordinator will determine if additional consultation should be sought from the

Construction Bureau. The Construction Bureau will determine if consultation should be sought from other bureaus

within ALDOT or an independent QCP. The Project Manager and the Project QCP will work with the Contractor to

create a plan and implement immediate corrective actions which shall be completed prior to the next storm event

but no later than 5 days after the inspection unless prevented by unsafe weather conditions. This corrective action

may require a suspension of all other operations. If permanent corrective measures cannot be implemented within

the 5 day timeframe, then written notification and detailed explanation will be given to ADEM. Additional




http://www.dot.state.al.us/conweb/pdf/Environment/ADEMFieldOffices.pdf




2.5

inspections will be performed as needed until the observed deficiency can be documented as corrected, satisfactory,

and in compliance with the ADEM permit.

QCP Site Evaluations

The Operational/Project QCP, will conduct a project inspection and CBMPP review a minimum of every six months.

These evaluations will be documented on the ALDOT QCP CBMPP Evaluation Log. A copy of the inspection report

and any associated correspondence will be added to the CBMPP.

ALDOT Central Office Reviews

Additional project inspections and CBMPP reviews will be conducted by the ALDOT Construction Bureau as needed.

These reviews are intended to aide construction personnel in maintaining compliance with the ADEM permit.

TURBIDITY MONITORING

Turbidity monitoring is required on all Priority Construction Sites that disturb 10 or more acres of erodible material.

The Environmental Concerns and Commitments section of the CBMPP will indicate if the project is a Priority

Construction Site. A Project Note will be included in the plans indicating that turbidity monitoring is required and the

applicable drainage areas if it is not required for the entire project.

Primary and Secondary Stormwater Discharge and Background Points are all potential locations for turbidity

monitoring. Current regulations require that our construction stormwater discharges not increase the turbidity of

the receiving water by more than 50 Nephelometric Turbidity Units (NTUs) or cause a substantial visible contrast. In

order to document compliance with these requirements, the Permittee will conduct turbidity monitoring by

sampling channelized construction stormwater discharges and measuring the NTUs with a portable turbidimeter.

The Permittee will conduct representative turbidity monitoring in each individual drainage area. Representative

turbidity monitoring will be defined as sampling at the Primary Stormwater Discharge Point and every Background

Point of a drainage area. The data from these points will allow the Permittee to determine whether the drainage

area is in compliance with the 50 NTU above background limit. If a substantial visible contrast is observed at a

Secondary Stormwater Discharge Point, an additional sample will be taken at that location. All results from turbidity

monitoring will be recorded on the Stormwater Turbidity Sampling Report in the SWTS.

There are some instances when stormwater sample collection will be waived in a drainage area. When a required

sample is not collected, it must be due to one of the following acceptable reasons and this will be recorded on the

Stormwater Turbidity Sampling Report in the SWTS. In all cases photographic documentation is required.

Prior to Construction – Turbidity monitoring in a drainage area is encouraged but not required to commence

until work has begun in that drainage area. This reason is also acceptable in cases where there is not channelized

flow because the pipe or ditch at that sampling location has not been constructed.

Insufficient Flow – There must be sufficient channelized flow in order to collect a stormwater sample. In some

cases there may not be sufficient flow until there is a considerable amount of precipitation. Sufficient

channelized flow shall be defined as the ability to collect a sample of construction stormwater without the

sample collection container touching the bottom of the conveyance (ex. ditch bottom, stream bed, pipe, etc.).







2.5

Hazardous Condition – There may be times when it is not possible to take a stormwater sample at a turbidity

monitoring point due to a life-threatening hazardous condition. The details of the hazardous condition will be

documented on the report.

Monitoring Suspended – Turbidity monitoring will continue in a drainage area until the final required

stabilization is installed or applied, erosion is controlled to the maximum extent practicable, and stormwater

sampling results have shown the drainage area to be in compliance for the last two months. If all of these

requirements have been met, then turbidity monitoring may be suspended in a drainage area. However, if the

project has not been accepted for maintenance, turbidity monitoring will resume if the drainage area is

subsequently disturbed, there is evidence of substantial erosion, or a substantial visual contrast is observed at a

primary or secondary discharge point.

SAMPLING PROCEDURE

Sampling of construction stormwater will be conducted for channelized flow at the nearest accessible location to

the sampling point identified in the plans. Construction stormwater samples will be collected and analyzed by the

Permittee using a portable turbidimeter provided by the Contractor. Prior to sampling, the QCI will read the

turbidimeter user manual and be familiar with proper equipment operation and handling procedures. Results will

be recorded on the Stormwater Turbidity Sampling Report in the SWTS.

Contractor Furnished Sample Analysis Equipment

Contractor retained turbidimeters will be used for analyzing construction stormwater samples. Approved

turbidimeters are included on List II-24 “Temporary Erosion and Sediment Control Products”. The Contractor shall

provide documentation of professional equipment calibrations. The Contractor shall also provide a calibration kit

(calibration standards, soft lint-free cloth, and silicone oil) and sample tubes from the turbidimeter manufacturer.

The Permittee’s QCI will ensure that the calibration standards are not expired. The Permittee’s QCI will verify

calibration and, if needed, calibrate the turbidimeters each day prior to sampling analysis.

Permittee Furnished Sample Collection Equipment

1. Sample Collection Containers – one pint minimum volume, polyethylene or glass, wide-mouth container,

preferably with a lip designed for pouring

2. Sample Storage Containers – one pint minimum volume, polyethylene or glass, wide-mouth container, with

a secure lid

3. Cleaning Brush(es)

4. Phosphate-Free Detergent

5. Distilled or Deionized Water – gallon jugs for use in the project office

6. Squirt Bottle – fill with distilled or deionized water for use in the field

7. Waterproof Labels – for labeling sample storage containers

8. Waterproof Ink Pens – for labeling sample storage containers

2.5

Equipment Cleaning

For accurate readings, sample tubes will be kept completely clean both inside and out. Sample tubes will be handled

by the lid and will not be touched on the glass as much as possible. Scratched or etched sample tubes will be

discarded and replaced. Do not reuse sample storage containers or sample tubes without proper cleaning. Sample

collection containers, sample storage containers, and sample tubes will be washed after each day of use as follows:

1. Wash with a brush and phosphate-free detergent.

2. Rinse three times with cold tap water.

3. Rinse three times with distilled or deionized water.

Additionally for samples tubes, wipe the exterior with a soft, lint-free cloth. If there are minor imperfections in the

glass, a light coating of silicone oil should be applied to the exterior surface and wiped with the cloth to create a thin,

even film over the entire surface.

Sample Collection

Construction stormwater samples will be collected by grab samples from flowing channelized discharge. The sample

will be collected from the center of the main flow of the discharge or stream or, if too deep or unsafe, as near to that

location as possible. If you must stand in the water to take the sample, collect the sample upstream of you and any

area that you disturb. Collect downstream samples in the drainage area first beginning with the Primary Stormwater

Discharge Point, any required Secondary Stormwater Discharge Points, and ending with any Background Points.

Rinse the inside of the sample collection container in the water to be sampled prior to each sample collection. To

collect a sample, hold the sample collection container near the base and turn it with the opening downward towards

the water surface. Being sure not to touch the bottom of the conveyance, plunge the container into the water 8-12

inches beneath the surface or halfway down for shallower flows. Turn the container opening away from you and in

an upstream direction to collect the sample.

Sample Analysis

The sample analysis will be conducted in the field immediately after sample collection. Place the turbidimeter on a

level surface; do not hold it in your hand. Fill the sample tube by pouring from the collection container. Securely cap

the sample tube and follow the turbidimeter manufacturer’s operation instructions to determine the turbidity of

the construction stormwater sample. Results will be recorded as follows:

NTU Range Number of Decimal Places

0.0 to < 1.0 2

1 to < 10 1

10 0

Sample tubes may be reused in the field if they are rinsed with distilled water immediately after each analysis.

Samples Exceeding 1000 NTU

Construction stormwater samples that have readings exceeding 1000 NTU will be further analyzed in the project

office. Each sample storage container will have a waterproof label with a record in waterproof ink of the project

number, sampling point identification number, sample date, sample time, and the name of the QCI who collected

the sample. Fill the sample storage container by pouring from the collection container. Transport the sample to the

project office immediately for analysis. If analysis cannot be conducted within 15 minutes of the sample collection

time, the sample must be cooled to 4°C [39.2°F] and can be held for up to 48 hours only.



2.5

Agitate the stormwater sample by repeatedly inverting the container to re-suspend any potentially settled particles.

Using turbidity-free distilled water, dilute the sample until the reading is below 1000 NTU. Compute the turbidity of

the original sample by multiplying the turbidity of the diluted sample by the dilution factor. For example, if 5 units of

volume of dilution are added to 1 unit of volume of the sample, and the turbidity of the diluted sample is 500 NTU,

then multiply 500 NTU reading by the total 6 units of volume to equal a 3000 NTU turbidity measurement for the

original sample.

RAINFALL JOURNAL

Rain Gauges

Rain gauges will be utilized on all ALDOT construction sites. Rain gauges will be identified by the letter ‘G’ followed

by an integer, which is the same as the associated Primary Stormwater Discharge Point of the drainage area in which

it is located. Rain gauges will be located in an open area such that the measurement will not be influenced by outside

factors such as overhangs, gutters, and trees. Rain gauges will be spaced approximately 3 miles apart. Daily rainfall

amounts are rounded and reported to the nearest five hundredths (0.05”) of an inch in the Rainfall Journal of the

SWTS for each rain gauge. This is in addition to the weather and rainfall entry reported in SiteManager or CAMMS.

The Rainfall Journal will be printed and added to the CBMPP at the end of each month.

RainWave Precipitation Monitoring

At least one RainWave Precipitation Monitoring point will be utilized for all projects designated as a Priority

Construction Site or that have 20 or more acres of disturbance. The location of the RainWave points will be selected

by the Construction Bureau. The Project QCP may request additional RainWave points. RainWave Precipitation

Monitoring points will be identified by the letter ‘R’ followed by an integer, which is the same as the associated

Primary Stormwater Discharge Point of the drainage area in which it is located. RainWave points will be located

within the project limits and ALDOT ROW at a culvert site, bridge site, or other Primary Stormwater Discharge Point

with potential environmental impact to a water of the state.

After the project has been let, the Construction Bureau will forward the RainWave Information Form to the

Region/Area Stormwater Coordinator. After the project has been awarded, Region/Area Construction personnel will

enter a Precipitation Monitoring Service type Request for Consultant (RFC) in CPMS for the RainWave service if one

does not already exist. The RFC will be reviewed for approval by the Area Operations Engineer the Region Engineer,

and the Chief Engineer, if applicable.

Upon final approval of the RFC, Region/Area Construction personnel will enter a Consultant Purchase Order (CPO)

in CPMS. After the CPO is approved, the Region/Area will send a Notice to Proceed to the Consultant. This

notification will include a copy of the CPO and the RainWave Information Form.

Automatic email notifications of daily precipitation totals and monthly precipitation summaries will be sent to the

Project QCP, the Project Manager, and the Project QCI for entry into the Rainfall Journal of the SWTS. The names

and email addresses of these individuals will be added to the RainWave Information Form by the Region/Area

Stormwater Coordinator. The charge code for billing purposes and the monitoring end date will also be added. The

estimated cost for the work should take into account the initial setup fee and the monthly fee for the proposed

project time which can be automatically calculated by the previously utilized ALDOT Funds Transfer Request. One





2.5

month prior to the end of the precipitation monitoring contract each project, the Region/Area Stormwater

Coordinator will receive an email with the option to extend the duration of the service.

STABILIZATION REQUIREMENTS

Temporary stabilization is necessary to minimize erosion of soils and transport of sediment. Temporary BMPs

such as Stabilized Construction Entrances, Perimeter Sediment Barriers, and Sedimentation Basins shall be

installed as soon as possible during the clearing and prior to beginning grading operations in the contributing

drainage area. Additional Temporary BMPs shall be installed during grading to protect waters of the state,

construction stormwater discharge points, construction stormwater inlets, and to divert stormwater flows

around exposed work areas.

All exposed areas that are not undergoing active construction for a period of 7 days or more require temporary

stabilization. Temporary Mulch shall be applied if the exposed area will remain inactive for less than 60 days.

Temporary Seed and Temporary Mulch shall be applied if the exposed area will remain inactive for 60 days or

more. Rolled and Hydraulic Erosion Control Products should not be used for temporary stabilization.

Temporary erosion and sediment control BMPs should be removed, unless otherwise directed by the plans,

as the final required stabilization is installed or applied in the drainage area and they are no longer serving

their intended purpose.

Final or permanent stabilization is necessary to prevent erosion of soils and transport of sediment. Final stabilization

should be continuously pursued by transitioning from temporary BMPs to permanent BMPs as grading advances

while maintaining continuous erosion and sediment control. Final slope stabilization will be installed or applied in

vertical increments that should not exceed 20 feet as grading progresses. Forms of final required stabilization

includes, but is not limited to, permanent seed and mulch, permanent seed and an erosion control product, sod,

aggregate surfacing, riprap plating, concrete, and asphalt.

Once the final required stabilization is installed or applied to an area the Contractor is allowed to expose an

equivalent amount of acreage in another location. Additionally, any stormwater sampling locations in a drainage

area which has final stabilization are eligible for evaluation for turbidity monitoring suspension. Once final required

stabilization is in place on the entire project, vegetation is fully established, and the project is accepted for

maintenance, the Permittee’s QCP will request the coverage under the ADEM Construction General Permit be

terminated. The Contractor is responsible for all erosion and sediment control until coverage under the ADEM

Construction General Permit is terminated or 30 calendar days after submission of the termination request to ADEM,

whichever occurs first. Required construction stormwater inspections by ALDOT personnel will cease according to

the same terms.

QUALIFIED CREDENTIALED INSPECTOR TRAINING

All personnel responsible for construction stormwater inspections must be certified through an ADEM-

approved initial 8-hour QCI training course. This applies to ALDOT, Contractor, Subcontractor, County, City,

and ALDOT Consultant personnel. Additionally, all QCIs must participate annually in an ADEM-approved, 4-

hour QCI refresher training course. The ALDOT Construction Bureau conducts an ADEM-approved QCI annual

refresher training course available to ALDOT, County, City, and ALDOT Consultant personnel for recertification.


ALDOT Approved Treatment Chemicals Contract requirements regarding flocculants and chemical stabilization during construction may be found in the form of

contract pay items on the Quantities Sheets and their usage locations are shown on the Erosion and Sediment Control Sheets

in the plan set. Proper usage requirements are included in the applicable 2017 ALDOT Special and Standard Highway

Drawings book and applicable 2012 ALDOT Specifications. These products may only be used if they have been reviewed and

included on the applicable approved products lists of the ALDOT Materials, Sources, and Devices with Special Acceptance

Requirements Manual which is maintained on the ALDOT website. Safety Data Sheets and manufacturer’s dosage instructions

for these products are also maintained on the ALDOT website. Please visit the applicable ALDOT webpages for the most

I. Introduction

The purpose of this plan is to ensure that construction environmental protection issues, including erosion, sediment and

turbidity control, are realized and managed by both ALDOT and the Contractor at the earliest possible date. This plan will be

used in conjunction with requirements set forth in contract documents for this project and should be considered an

implementation plan for these requirements.

In order to successfully control erosion, sediment, turbidity, and other pollutants, the nature of road and bridge construction

requires that both the Contractor and ALDOT be flexible in the implementation of this plan and flexible in the implementation

of Best Management Practices (BMPs). BMPs will be implemented at locations and during stages of construction when they

will be effective and are applicable with concurrence of the Engineer. It is understood that the definition of Best Management

Practices includes any action taken by the Contractor or by ALDOT to protect water quality and/or private property.

Certain operations as listed in the Contents may not be a part of this contract. This has been made clear under the appropriate

section.

The creation and submission of this document is evidence that the Prime Contractor for the project has read the CBMPP

document is aware of specification requirements regarding water quality protection, and agrees to implement this SWMP

and the CBMPP as a whole for the life of the project. It is understood that if the plan is found to be satisfactory, the plan

will not be approved by the Engineer, but will be accepted as complete with or without exceptions.
