APPENDIX ASUPERFUND PROCESS

A.I REM XI AND SUPERFUND IMPLEMENTATION

CERCLA established a national program for responding to releasesof hazardous substances into the environment. In addition, theNational Oil and Hazardous Substances Pollution Contingency Plan(NCP) establishes the process for determining appropriateremedial actions at Superfund sites. Together, CERCLA and theNCP require that a remedial action selected for a Superfund sitebe cost-effective and that it be adequate to protect publichealth. .__—_.. ..._.. ... ._...._..——— _._ . . _ .

A.2 THE RI/FS PROCESS

In accordance' with the NCP, potential hazardous waste sites aresubjected to preliminary assessment, and, if necessary, detailedsite inspection. If evidence _ of hazardous waste activity isfound, posing an actual or potential threat to public healthand/or the environment, it must be determined whether removal ofthe wastes is necessary.

If removal "actions are not required, an evaluation is made of thepotential threat to public health and/or the environment relativeto that posed by other potential hazardous waste sites. In thismanner, a relative ranking is developed as the basis forinclusion of the site on the National Priorities List (NPL) .Inclusion of a site on the NPL is a prerequisite for expenditureof monies from Superfund to conduct a more detailed siteinvestigation and evaluation of remedial action alternatives.

?=»..SR302396

A detailed site investigation and a remedial alternativeconsideration are conducted as a Remedial Investigation/Feasibility study (RI/FS), in accordance with the NCP. The RI/FSis an integrated approach. The RI characterizes the nature andextent of contamination at the site, identifies potential contam-.inant migration pathways and exposure routes, and evaluates thepresent and/or potential threat to the public and the environmentdue to site contamination. Data gathered during the RI are usedfor the development and -evaluation of possible remedial actionalternatives in the FS. In the FS phase report, feasible tech-nologies (e.g., surface water diversion, capping, landfilling,treatment) are defined to mitigate or eliminate the health orenvironmental threats identified in the RI. These technologiesare assembled into alternative remedial actions and subjected toan initial screening to identify those that address the goals ofremedial action and can be implemented, and to eliminate -inappro-priate and more costly alternatives. Those alternativesremaining following the initial screening phase are subjected tomore rigorous evaluation.

The RI/FS process results in an objective, comparative evaluationof the most appropriate remedial alternatives to meet the cleanupobjectives for the site. This evaluation is prepared in the formof a draft report and subjected to public and agency review andcomment. A final RI/FS report is prepared summarizing commentsreceived during the public review period and comment responses.Based on the final RI/FS report, EPA selects the recommendedremedial action alternative. — —

The purpose of the REM II program is to provide technical andmanagement services in support of EPA remedial planning enforce-ment and activities at selected uncontrolled hazardous substance

fiR302397

disposal sites. This program was established under CERCLA, com-monly re_ferred to as Superfund. EPA's Hazardous Site ControlDivision (HSCD), through Contract No. 68-01-6939, has employedCamp Dresser & McKee Inc. (COM) of Boston, Massachusetts to

3

implement remedial response activities in EPA Regions I through x.

Contract No, 68-01-6939, titled "Performance of Remedial ResponseActivities at Uncontrolled Hazardous Waste Sites," and called"REM II," is.a 4-year contact to provide:

• Remedial Investigation.

• Engineering feasibility studies.

• Oversight of remedial planning and implementationproj ects performed by states and/or respons ibleparties.

• Engineering design services.

• Monitoring.

• Resident engineering, training, technical services, andprogram management.

• Support to EPA.

Figure A-l provides a simplified logic diagram for the majorcomponents associated with the performance of an RI/FS by theREM II team. The initial documents prepared for this assignment '.are components of the L. A. Clarke site Work Plan and ProjectOperations Plan (POP). These documents define the objectives and

scope of the RI field activities. The results of the fieldactivities are reported in the RI, Sections 1 through 5, with theremedial alternatives developed and discussed in the FS, Sections6 through 9 of this document.

j

Note that additional field work (i.e., Phase III activities) isrequired to obtain information necessary to confirm existingmodels and more precisely cost remedial alternatives. Therefore,this document only addresses site remediation considerations andinitial technology screening.

GENERAL NOTES FOR TEST BORING LOGS

1. NUMBERS IN "SAMPLE SPOON" COLUMN INDICATE BLOWS REQUIRED TO DRIVE A 2 INCHO.D., 1-3/8 INCH I.D. SAMPLING SPOON 6 INCHES USING A 140 POUND HAMMER FALLIN30 INCHES ACCORDING TO ASTM D-1586,

2. VISUAL CLASSIFICATION OF SOIL IS IN ACCORDANCE WITH TERMINOLOGY SET FORTH IN"IDENTIFICATION OF SOIL." THE UNIFIED SOIL CLASSIFICATION SYMBOLS SHOWN INPARENTHESES ARE EASED ON VISUAL INSPECTION.

3. ESTIMATED GROUNDWATER LEVELS INDICATED BY ^ ; THESE LEVELS ARE ONLY ESTIMATESFROM AVAILABLE DATA AND MAY VARY WITH PRECIPITATION, POROSITY OF THE SOIL, SITETOPOGRAPHY, ETC. PIEZCMETER LEVEL OF DEEP AQUIFER INDICATED BY V .

A. REFUSAL AT THE SURFACE OF ROCK, BOULDER, OR OBSTRUCTION IS DEFINED AS APENETRATION RESISTANCE OF 100 BLOWS FOR 2 INCHES PENETRATION OR LESS. '

5. THE BORING LOGS AND RELATED INFORMATION DEPICT SUBSURFACE CONDITIONS ONLY AT THESPECIFIC LOCATIONS AND AT THE PARTICULAR TIME WHEN DRILLED. SOIL CONDITIONS ATOTHER LOCATIONS MA.Y DIFFER FROM CONDITIONS OCCURRING AT THESE BORING LOCATIONS.ALSO, THE PASSAGE OF TIME MAY RESULT IN A CHANGE IN THE SUBSURFACE SOIL ANDGROUNDWATER CONDITIONS AT THESE BORING LOCATIONS.

6. THE STRATIFICATION LINES REPRESENT THE APPROXIMATE BOUNDARY BETWEEN SOIL ANDROCK TYPES AS DETERMINED FROM THE DRILLING AND SAMPLING OPERATION. SOME VARIATIONMAY ALSO BE EXPECTED VERTICALLY BETWEEN SAMPLES TAKEN. THE SOIL PROFILE, WATERLEVEL OBSERVATIONS AND PENETRATION RESISTANCES PRESENTED ON THESE BORING LOGSHAVE BEEN MADE WITH REASONABLE CARE AND ACCURACY AND MUST BE CONSIDERED ONLYAPPROXIMATE REPRESENTATION OF SUBSURFACE CONDITIONS TO BE ENCOUNTERED AT THEPARTICULAR LOCATION.
