Enviornaental Safeguards

a. Csncral

The goal of the Exploration Plan i s the gathering of aore Infornation on the geology of the lease area, in a safe manner, with minimal disruption of the enviornment. Various r u l e s , regulations, codes, laws and pratices have been developed over the years, which w i l l ass i s t the operator to conduct operations in the manner. OCS Order Number 7 speci f ical ly deals with the environmental safeguards and safety of the d r i l l i n g and production operations.

Envlronaental safeguards are bui l t into the operations in several ways: in the original design of equipaent and systea of operations, In the gathering of personnel, ih the preparation of procedures for operations and also in the procedures and ava i lab i l i t y of equipaent for reaedial actions ln cases of emergencies.

b. Envlronaental Safeguards in the Design

The d r i l l i n g unit I s bui l t to prevent pollution of the Gulf of Mexico by u t i l i z i n g a systea of curbs, gutters and surface drains which direct a l l f lu ids to a containment systea. This system recovers hydrocarbons before water l s discharged Into the Gulf of Mexico.

Pennzoil has f i l e d to have Green Canyon Area Block 45 covered under the General NPDES Perait No. TX 0085642.

Liquid waste a a t e r i a l , including sewage froa the l iv ing quarters wi l l be treated in n MMS approved sewage plant on the d r i l l i n g unit prior to discharge into the ocean. Solid waste materials are compacted and transported to shore for disposal.

Dri l l ing operations are monitored by Pennzoil representative on board. Par t i cu lar care is exercised to minimize disruption of the environment. Dr i l l ing mud additives are selected to prevent a l a s t ing impact on the surroundings. A l i s t of commonly used additives u t i l i zed by Pennzoil i s shown In Appendix 7. Items that cannot be treated properly w i l l be transported to shore for d isposal .

11.4

c. Training of Personnel and Procedures

Regular training of operacions personnel is a necessary complement to the pollution prevention features ln the design of equipment and operations. Operator awareness is achieved by regular training and enforcement of procedures. The drilling unit is inspected daily. A procedure of the reporting of and dealing with oil spills has bssn escabilished by Pennzoil in accordance wich che requirement of OCS Order Number 7, which is incorporated In Pennzoil's "Disaster Contingency Plan".

d. Pollution Control Equipment and Contingency Plan

Pennzoil has a Disaster Contingency Plan which haa been approved by the Area Supervisor of che HMS. The plan describes procedures *or action in dealing wich any major disasters, such as o i l s p i l l s , f i r s s , blowoucs, ecc. It describes in decail:

... Duties to be performed when a dissscsr occurs, wich an indication of priority.

... Assignment of duty and designation of authority.

... Communication and reporting requirements (company and ou c s ide agenc ies).

As a member of Che Clean Gulf Associates, Pennzoil has access co Che equipment chis association keeps on standby in the various areas of the Gulf of Mexico. Appendix 8 shows an inventory of the available equipment.

Pennzoil estimates that clean up operacions could begin wichin 18 hours afcer ics Dlsascer Contingency Plan wss put in eff< 't.

5. Safety Features

As la che cass wich chs enviornmsntal safeguards, safecy aspects muse be a combination of design, operator awareness and the availability of suitable emergency equipment. Over che years, che Oil Industry and Chs Federal Government have Issued a considerable nuaber of standards, recommended practices and laws govsrning minimum rc i -irements. Design of equipaent for Pennzoil's operations require? JIJS applicacion of a l l available standards ln Chs strictest ia. r-r. The most important of chsss are listed below:

Ct. 5

. . . OSHA

. . . OCS Orders of the MMS

. . . API Standards and Recommended Practice

. . . ASME Codes

... ASTM Standards

... ANSI Standards

... AISC

... American Welding Society

... NFPA (NEC)

Safety systems are incorporated in the design of equipment and operational procedures as required by the OCS Orders.of the MMS. OCS Order Nunber 2 specifically provides detailed informtion on ths drilling operations and Pennzoil adheres strictly co these rules and regulations.

Automatic ,:as and fire detection systems are incorporated in the unlc Co alarm operacions personnel in case of emergencies. Euqipment Co deal vich emergencies (life vests, rafts, buoys, fire extinguishing equipment, l i f t boats, etc.) i s located strategically on the drilling unit. Frequent training sessions are held Co keen operacions personnel alerc and familiar wich procedures and operacing inscruecions ror equipment.

5. Geophysical Analysis of the Drilling 0 oration

Pennzoil's geophysicist has reviewed the available seismic informacion and has concluded that the presence of several possible shallow drilling hazards over the surveyed area may exisc. A Geophysical Report of Pr -ed Well Locations concerning possible shallow hazard ihown in Appendix 9.

C. DESCRIPTION OF THE AFFECTED ENVIRONMENT

Geology

a. Bathymetry

The seafloor in Green Canyon Block AS is illustrated by tbe Bathymetry Map ln Appendix 3.

b. General Description

Bottom sediments are predominately a mixture of s i l ty clay and clayey sand as shown on Visual No. 3 of the EIS for Lease Sale No. 45 (1).

c Submarine Geology

In the offshore area of the Gulf of Mexico, a number of geological hazards are present. A possibility of lowouts exists due to the presence of shallow gas deposits within the sediment. Deeper* extra high pressure zones can also cause blowouts during drilling operations. A third hazard is the highly unconsolidated, gas saturated sediment being deposited by the river systems. This lease area is located ln a stable part of the Gulf of Mexico and mudslides are extremely unlikely. Seismic risk is considered neg­ligible in the western part of the Gulf of Mexico (EIS Lease Sale Number 51 (2)) .

Active faults, gas seep areas and seep mounds do pose dangers to offshore seabottom operations. Experience from other wells ln the area has shown Pennzoil that extreme caution must be exercised while penetrating the shallower layers and drilling operations personnel are made aware to be prepared for these situations. Pennzoil's geophysicist has reviewed the available seismic data and no extraordinary problems are expected for the dril l ing operations in the lease area. The Shallow Hazard Survey Report is hown in Appendix 9 of the Plan.

d. Mineral Deposits

No known important mineral deposits exist ln the vicinity of the lease area.

s. Aquifers

No frssh watsr squifsrs exist ln the area that have potential for onshore use.

III.7

2. Mete orology

a. Ganaral Weather Patterns

The climate of the Northern Gulf of Mexico Is determined by four major factors: The North America Continental land mess, che Azores-Bermuda high pressure c e l l , sub-tropical latitude and che relatively warm wacer of the Gulf of Mexico i tse l f . The principal influence i s che Gulf, resulting in a maritime tropical climate for che region. During che winter, polar continental air masses move southward into the Gulf of Mexico causing occasional sudden drops in temperature, resulting in stationary fronts which produce low clouds, rain and fog in the coastal areas. By spring the Bermuda high develops its influence over the region, thus improving the weather considerably. During the summer, southerly winds of the Bermuda high bring warm, molsc, tropical a ir . Easterly waves and tropical storms appear in ch* Gulf during late summer and early fa l l . Over half of these storms become hurricanes during this season. During October and November, the Bermuda high loses i ts strength and allows continental air to again exert Influence on the Gulf of Mexico.

The western extension of the Bermuda hizh pressure ce l l dominates circulation throughout the year, weakening in winter and strengthening ln summer. Average pressures range fron 1015 millibars in summer to 1021 in wintertime. Temperatures vary with latitude in the region within narrow limits (17-20°C in winter vs. 29° C In summer). Relative humidities are high throughout the year and range from the low sixties to the high eighties.

The warmer months usually have convectlve cloud systems, which produce showers and thunderstorms. Cloudiness averages between 3/8 and 5/8 sky cover with relatively small seasonal variations. Fog formation as a result of warm, moist air from the Gulf is often formed in the period from November through April , lasting for a few hours daily.

Tha Azores-Bermuda high pressure ce l l dominates ths circulation ovsr che Outer Concinencal Shelf of the Gulf jf Mexico, particularly during ths spring and summer months. In the lace summer months there is s gsnersl norchwsrd shifc. During summer raonths, winds are predominantly southeasterly.

Ths iargsst and most destructive storms affecting che Gulf of Mexico are croplcsl cyclones. They occur most frequently between Juns snd lace October and chore is a relacively high possibility chat cyclones will csuss dsasgs in chs Gulf of Mexico each year. Ths E . I . S . of Lease Sals Nuaber 45 (1) provides extensive historical dsts on past croplcsl cyclones. Daasgs offshore from these cyclonee results primarily froa high winds and high tides. In addition to ths croplcsl cyclonee, extrs troplcsl cyclones occur in the srss. Thsss storms occur primarily ln the winter months end very grsstly

I I I .8

ln Intensity. A phenomenon known as a "norther" is quite common in this arss of ths Gulf of Maxico during tha winter months- It occurs when cold polar air moves southward from the cold interior of the North American Continent out over thi warm waters of the Gulf. The result may be strong gusty winds with considerable cloudiness and showers.

Rainfall ls s fairly evenly distributed throughout the year, with greatest amounts occuring during the summer months. July ls the wettest month (18 cm) and October the dryest (8 cm).

b. Air Qusllty

The onshore s i r qusllty ln Intrscosstsl City is characterized by ths industrial nature of this location. Many operating snd service companies hsve operstional basss in ths vicinity to support offshore operstions.

Offshore, ths existing air quality ls almost completely undisturbea in view of the distance to shore and the fact that no permanent operations hsve been conducted ln this lesse area. No data quan­tifying the air quality is available for this portion of the Outer Continental Shelf snd Pennzoil has not monitored tha air quality in the lease area.

Physical Oceanography

a. Sea Temperature and Salinity

Gulf wacers are generally warm. However, in the offshore ares, significant differences in tempersture may be seen seasonally and by depth. Annually, sia-surface temperatures in che lease area range rom approximately 18°.. to 28°C and bottom temperatures range from

i8 C to iO°C [Cochrane and Etter (8)1.

The salinity patterns in the Gulf of Mexico are mainly determined by: inflow of ocean waters through the Yucatan Strait, precipitation and inflow of fresh wster from land sour es, evaporation, circulation and mixing. Seasonality ls also known CJ strongly influence nearshore and offshors salinity gradients [EIS Lesse Ssls Number 45 (1)]. Salinity values for the lease area am approximately 36.0 pares per thousand (ppc) throughout ths vater eclumn (Nowlin (9)].

Temperature snd salinity both sffsct che saturation concentration of dissolved oxygen; although surfses lsyers are saturated wich oxygen, concentration levels diminish wieh depch due Co respiration and de­composition of animals and bacteria in near surfscs wstsrs (Cross (10)J.

b. Currents

Along tbe Louisiana Shelf west of the Mississippi River Deles, there

Flora and Fauna

Extensive information on the aquatic biota in the Outer ContinentaJ Shelf of the Gulf of Mexico is presented ln the Environmental Impact Stateaents for the various lease sales. Fcr this report, the E.I.S.'s for OCS Lease Sale Nuaber 45 (1) and Nuaber '1 (2) have been utilized as the main source of information.

a. Phytoplankton

Phytoplankton are important as the primary producers of the marine environmant, serving as the starting poi-.i in the marine food web, providing food for zooplankton, which in turn provides food for larger carnivores. Phytoplankton also play an Important role in the oxygen-carbon dioxide balance, and serve co detoxify (biodegrade) many prllutants found ln the Gulf. Van Baalen (3) has conducted a quantitative and qualitative study off the Texas Coast and reports 4.1 x 105 cells per liter st inshore stations, 7.8 x 10* at middle stations, and 2.6 x 103 offshors. This lesse area, being far off­shore, would f a l l in the last category. Seasonal fluctuations seea

III.11

to shov higher l - v s l * ' . ̂ mut months than In winter months.

b. Zooplankton

Zooplankton comprise a major link between producers and higher tro­phic levels in che offshore Gulf waters, rhe most abundant groups found (copedods), and many othe: zooplark*onic crust.-cea seem capable of Ingesting both phytoplankton and detritur paxticles and thus are highly important in converting energy in biomass in higher level organisms [LOOP (4)]. Park's study (5) show: a comlstanc decrease seaward in their abundance in terms of biomass. This de­crease was particularly pronounced in spring and summer months. As wich Che phytoplankton, ic is impossible co generalize abouc specific locacion aad extend of congentrations of zooplankton due to che extreae patchiness of che phytoplankcoa on which- many zoo-plankcars feed. [EIS Lease Sale Nuaber 51 (2)].

c. Nekcon

Nekton for che offshore waters are represented by five categories: marine mammals, reptiles, fishes, cephslopod mollusc* (octopuses snd squid) and certain crustaceans (shrimp and swims* ro- crabs). Most nekcon are limited in geographic and vertical rarges bv en­vironmental conditions: temperature, salinity, and available food. During the LOOP Studies (4), extensive investigations were conducted wich regard to the cish species composition. A total of 103 species were collected during monthly trawl samples wich an average of 55 species per monthly sample. Major influences on the fish catches were oxygen content of water, water depth, and distance offshore.

d. Benthos

The benches has both floral and faunal components. The floral re­presentatives are algae and seagrasses. The abundance of benthic algae is limited by the scarcity of sultanLe rocky substrates and light penetracion ln che wescern Gulf of Mexicc. Offshore sea-grasses are noc conspicuous in the wester Culf as a result of the adverse effects of low salinity and turbidity of the Mississippi cffluenc from the Delta to Galveston. The benthic fauna is composed of Infauna, those aminals that 11 e in the substrate like burrowing worms snd molluscs, and epifauna, whose animals that live on the substrsts like mollusc's, crustaceans, hydroids, sponges, anemones, and corals.

Ths bsnthos provide another chain in che conversion of energy fixed in organic dstritus Co detritus feeder of utilization by consumers in chs sediment and eventually consumers in che wacer column. Ths bsnthic communities for che Outer Continental Shelf are distributed largely by sediment type and depth of water. Factors which also control the occurence of benthic organisms are salinity, temperature, currents, snd food availability.

Ths sconcmlc activity chat has occursd ln chs areas bordering the Gulf of Mexico has been a signiflcanc part of che total economic acclvlcy of che Nacion. Business activity in these srates hes shown resistance co depressing forces present in the national economy. The Increase in domestic o i l prices has Led to a substantial increase in energy produccion related acdvl t ies in general over the already well established pattern. The FEIS for Lease Sale Number 58/58A (1?) provides extensive quantitative data regarding this subject.

b. Location and Sise of the Related Population and Industrial Centers and Existing Community Services

Pennzoil's base is located in Intracoast I City, Louisiana frora where personnel and supply movements are coord, lated. However, the whole coastal area from New Orleans co Corpus i r i s t i wich ics well established character of energy relaced .nduscries and supplies wi l l provide che necessary service required :->r che operscions associated wieh this plan.

0 D. ENVIRONMENTAL CONSEQUENCES

1. Geological Hazards

Geological hazards are discussed in Seccion C.l.c.

2. Mecerology

a. Effaces of Weather on che Plan

Only hurricanes or tropical storms could have a significant effect on ths operations. No significant effect of the weather on che pian is anticipated.

b. Effects of che Plan on Offshore and Onahore Air Quality

In Seccion B . l l , discharges have been qualified.

3. Physical Oceanography Impacts

Impacts on the seafloor fro* drilling operacions will cake che form oi discharged d r i l l cutclngs arc ..nd the placform. The Impact of this oper­ation, however, i s of short duration and highly localized. The impact on the water qualitv is again of short duration. Qualitative and quan­titative data are presented in Section B. l l . The Enironmental Pro­tection Agency ha issued effluent limitation guidelines for offshore cperations which . ennzoil follows rigidly. Monthly samples are taken to check on the operations and quality of treatment of liquid wastes discharged in to the Gulf of Mexico. Water quriity could be severely degraded locally as a result of accidental o i l spills or blowouts. Pennzoil has an extensive procedure for che reporting of and dealing with oil spills (Section B.10) in order to minimize impacts of such events. Judging from pest experience ln the Gulf of Mexico, however, oil and gas operations on the Outer Continental Shelf do not have a significant long term effect on the water quality, although short term effects in the immediate vicinity of the operations may be quite severe [EIS Lease Sale Number 51 (2)].

4. Impacts on Other Usas of the Area

a. Shipping Activities

The iapact of che accivicies assoclaced wich this plan on shipping are negligible. Only during che exploration activities will a drilling rig be present in the block. The rig w i l l be properly equipped with safety features and navigational aids in sccordsnce with ths rsquireaents of the MMS.

III . I S

b. Coaaercial and Sport Fishing

Asids from damage caused by o i l s p i l l s , there i s considerable tvldence that o i l and gas operations have a favorable impact on fishing activities since structures act as breeding grounds and a r t i f i c i a l reefs. No long term effect however, ls expected as a result from these exploratory activities.

c. Military Use

No effect i s anticipated.

d. Pipelines and Cables

There are no pipelines crossing Green Canyon Block 45.-'

•• Other Mineral Resource Development

Nc .apact i s expected on other mineral resources in the area.

f. Cultural Resources

Reference .s made to Section C.4.f.

g. Mariculture

No mariculture activity will occur in or near the Leasa Area.

5. Flora and Fauna

Oil and gas activities have an adverse effect on the phytop .anktor., zooplankton, and benthos. Discharges of muds and d r i l l cute lags create turbidity around the drlllling aree, which mav k i l l the groups of biota mentioned. Experience in the Gulf of /'.exico indicates, however, thet such effects are of short duration, cover a small area a"id r.*v« no long term impacts (Zingula 7). Impacts on nekton and marine mammals are considered negligible in view of the she : duration .ud '<••**!4zed cheracter of the operations associated with ;he L roves.a *xplt»» a^oi. Plsn.

a. Socio-Economic

1. Employment Population Centers and Cummuii- Service

Personnel requirements have been disc ss tf in Sec .{.or. v". Pennzoil's organization is presently sxi«v\n» .-nd local contractors and suppliers have been established in the arcs to serve the energy Industry. Pennzoil does not antic 4 ise. j significant increase in the personnol requirsaents assoc.« ttec with the activities covsred in this propossd Plan.

III.16

2. Public Opinion

The public opinion regarding activities related to the energy industry are discussed in Section C.6.C.

3. Effects on Transportation Systems

Transportation vessels supporting the exploration activity will be traveling between Intracoastal City and the Lease Area. Pennzoil does not anticipate that this plan will affect the existing traffic systems and availability of craft in a significant manner.

4. Scarce Resources

Resources required for tnis plan are capital and manpower. Contractors will be hired to provide equipment and manpower. Industry practices indicate that a contractor will merely shift personnel and equipment from job to job. No new demands will be placed on onshore support manpower.

Demands for Goods and Services

Based cn Pennzoil's past experience, che following quantities of supplies will oe required for the exploration activities offshore:

Diesei Fuel 600 barreLS per week

Potable/Drill Water :500 barrels per week

Cement 5000 sacks per well

Various Mud Chemicals 250 tons per well

Steel Tubuiars 250 tons per well

Additional requirements for supplies for the onshore base resulting from this plan are considered negligible. Ic is Impossible to es­timate the net effect of che exploration activities on fuel consump­tion in view of the fact that traffic requirements are combined for the general area.

Environmental Impacts

1. Conseruecion

No new construction activities are required for chis Exploration Plsn.

2. Ocher Impacts

No other Impacts srs sxpsctsd co occur.

III.17

Accident*

a. Unusual Nature

Exploratory drilling carries inherent risk of drilling into unknown formation atructures. In order to minimize the risk of blowouts, shallow drilling hazard surveys are carried ouc prior to this activity. The report on this survey ls provided in Appendix 9 of the Plan. The EIS for Lease Sale Number 58/58A (12) provide extensive documentation on the occurence and results of blowoucs.

b. Occupational Hazards

The proceccion of life Is an important factor in a l l drilling opera­tions. OCS orders from the MMS provide guidelines to,nini«ize risk and maximize safety. Although precautions are caken, accidents scill occur. The EIS for Lease Sale Number 58/58A (12) provides quancicacive daca and concludes chae in lighc of che nunber of offshore workers, che number of accidents Is considered low.

III.18

E. UNAVOIDABLE ADVERSE ENVIRONMENTAL EFFECTS

The iapacts on tha various systems have been discussed in Section I I I above. In general, ic can be seated thac a l l unavoidable adverse impacts which result froa routine operetlons wi l l be reletively localized and of shore duraclon. These impacts, however, wi l l be followed by unhindered natural recovery wichin a relatively shcrc time period [EIS Lease Sale Nuaber 45 (1)].

These impacts include:

. . . Temporary reduction in water quality due to discharges during che drilling opertions.

. . . Short Cera effect and possible ki l l ing of source plankton and bencho ln the immediate vicinity of the platform.

. . . Temporary reduction in air quality during che dri l l ing operacions.
