Extinguish all sources of ignition. 2. Isolate incompatible or reactive chemical substances. 3. Isolate all potential environmental receptors including drains, sumps, soil, etc. 4. Determine if the discharge is incidental' or non-incidental': • Discharges include, but are not limited to, any spilling, leaking, pumping, pouring, emitting, emptying, or dumping of oil that is not otherwise permitted under other programs. o For incidental discharges - attempt to stop or contain the discharge at the source without endangering yourself or others. o For non-incidental disdlarges - immediately report the discharge to the Cross Hudson representative. 5. Reporting to outside agencies - CHC representatives will conduct necessary reporting to outside agencies. • If a discharge of oil or hazardous material has entered the environment - report to New York State Department of Environmental Conservation C'NYSDEC"). • If a discharge migrates off of the construction site, report to the Local Fire Department. • If a discharge enters the sewer system, report to New York City Department of Environmental Protection. • If a discharge causes a sheen or discoloration of navigable waters or adjoining shorelines - report to the National Response center C'NRC"). 6. Recover material discharged and clean up discharge area. 7. Decontaminate tools and equipment, Collect all rinsate and debris. 8. Dispose of waste materials in accordance with all applicable regulations and Cross Hudson procedures. 9. Cross Hudson representatives will conduct follow-up written notifications to applicable agencies. 10. Cross Hudson representatives will coordinate an lnddent analysis with the involved parties to develop plans necessary to prevent recurrence. 1 Based on guidance contained in the Spill Guidance Manual published by NYSDEC, "Incidental" discharge is defined as a discharge which meets ~ of the following criteria: 1) The quantity is known to be less than S gallons; 2) The discharge is contained and under the control of the fadlity; 3) The discharge has not and will not reach the state's water or any land: 4) The discharge is cleaned up within 2 hours of discovery. A discharge is considered to have not impacted land if it occurs on a paved surface such as asphalt or concrete. A discharge in a dirt or gravel parking lot is considered to have impacted land and is reportable. 2 "Non-incidental" discharges are those discharges that fail any of the above criteria for incidental discharge and any amount that impact environmental receptors. The Independent Inspector will conduct external notification and reporting as required to regulatory agencies and/or first-responders. IX H-B H-14 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 1.0 INTROPUCTION The Cross Hudson Project involves the construction of a 670 MVA, 345 kV AC electric generator lead connecting the Bergen Generating Station in Ridgefield, New Jersey to the Consolidated Edison (ConEd) West 49"' Street Substation in New York City. The cable System will be composed of one (1) underground Alternating Current ("AC") circuit that will originate at a 230-345 kV switchyard to be constructed at the Bergen Generating Station. The Project consists of installing cables along a corridor approximately 8 miles in length, of which approximately 3.5 miles will be located on land in New Jersey, 4.0 miles beneath the Hudson River, and 0.5 miles in New York City C'NYC"). The Manhattan segment lndudes those portions of the Project between the West 49"' Street Substation connection and the temporary cofferdam at the end of the HOD borehole. The cable system will be composed of self-Contained Fluid Filled ("SCFF") cable installed in underground conduits and duct banks. Using site-appropriate construction techniques, the undergrOUnd cable system will be installed along the indicated route between Bergen Generating Station and the Hudson River. The cable system in the Manhattan 5egment consists of two components: a water component and a land component. The water component will be buried in the bed of the Hudson River Within conduits installed by horizontal directional drilling ("HOD"), and will make landfall in New York City between Piers 94 and 95. The land component uses site-appropriate construction techniques, including HOD (where the land component meets the water component) and conventional trench and cover techniques, the cable system will be installed from the area where landfall is made to the ConEd West 49"' Street Substation. In addition to the three main conductors, the system includes two fiber optic cables for monitoring, relaying, and communication purposes. The land installation will also include a distributed temperature sensor ("DTS"). This Spill Prevention Plan ("SPP'1 contains infonnation pertaining to the prevention of spills, containment of spills, response and dean-up measures, and reporting procedures for the construction of the Manhattan Segment of the Cross Hudson Project. This plan meets the spill prevention and planning requirements of the United States Environmentai Protection Agency's ("US EPA") Oil Pollution Prevention Regulations (40 CFR 112). A Cross Reference Table has been provided at the beginning of this SPP for the convenience of the reader should the format of the SPP deviate from the sequence specified in 40 CFR 112. 2.0 SITE DESCRIPTION 1.

Oil containing equipment located at the site that contains less than 55 gallons of oil (l.e., various pieces of machinery, portable containers, and tanks) is exempt from the requirements of this SPP. Table 4-1 contains a summary of all oil containing devices and storage containers that are subject to the provisions of this SPP. All petroleum spills must be reported to the NYSDEC within two hours of discovery, except those which meet all of the following criteria: • The quantity is known to be less than 5 gallons: and • The spill is contained and under the control of the spiller: and • The spill has not and will not reach the State's water or any land: and • The spill is cleaned up within 2 hours of discovery Workers will be informed of these notification requirements and will report any spill to the project foreman immediately after discovery. Site plans were developed in accordance with the requirements of the SPP regulations. Figure 1-1 provides a site plan for Cross Hudson that includes the locations of storm drains and site drainage (refer to Section 3.0 for a detailed discussion). 3.0 FACILID DRAINAGE AND MANAGEMENT OF RUNOFF 3.1 TooograPhy The construction site is located on relatively flat terrain located in an urban setting. The majority of the construction will occur in developed, paved areas. The Hudson River is located to the west of the site. The site is not located in or around any wetland areas. The cable system will make landfall in New York aty between Piers 94 and 95. The Manhattan Segment Project Area generally consists of developed properties with impervious surfaces. 2 H-I6 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 The Project Area elevations range from approximately 8 feet North American Vertical Datum 1998 (NAVD88) where the cable makes landfall to approximately 20 feet NAVD88 in the vicinity of the ConEd West 49'" Street Substation. At the location where the Splicing Chamber will be constructed, elevations range from approximately 13-20 feet NAVD88. Along the upland cable route between the Splicing Chamber and the ConEd West 49'" Street substation, elevations range between approximately 16-20 feet NAVD88. 3,2 Surface Water The major surface water resource in the vicinity of the site is the Hudson River, which is located approximately between SO feet and 200 feet west of the western boundary of the site. The Hudson River flows in a southerly direction and empties into New York Harbor. 3,3 Pirectlon of Flow • 3,3,1 Upland Segment If there is a release to the environment at this construction site, the most likely environmental receptor potentially affected by the release is paved surfaces or exposed soil if a spill occurs adjacent to an excavation. Surface drainage from the construction site occurs by overland flow from higher terrain to the adjacent lOW-lying areas. Storm drains, which are located throughout the site, are also possible receptors. Releases Within the paved surfaces, splicing and dielectric fluid chamber and the ConEd West 49'" Street Substation would be retained by the impervious floors and walls of these buildings and detected by construction personnel for subsequent cleanup. Table 4-1 provides a summary of secondary containment and engineering measures designed to reduce spill potential. Small containers of oil (less than SS gallons) may be stored and used throughout the site. The threat of release from these containers is greatest. during relocation or use by the Contractor who would immediately observe and report a release and take response actions using absorbent material and/or drain coversto divert oil from storm drains. Control and containment measures that reduce the likelihood that oil will impact surface water bodies in the event of a spill will be implemented. Table 4-1 summarizes all oil containing equipment and storage locations, containment measures, as well as the most likely route of exposure and pollution prevention strategies designed to minimize exposure. If stormwater collects in any secondary containment area, it will be visually inspected for evidence of an oil leak (t.e., visible sheen) before being manually removed. 3 H-17 Spill Prevention Plan ENSR AECOM Cross Hudson Project February 2008 There are a number of stonn drains, designed to collect stonnwater runoff, located along the proposed construction route. The majority of stonnwater runoff is directed to the Hudson RiVer, the local drainage outletfor Manhattan. 3,3,2 HUdson Riyer Any spills that occur from marine vessels or as a resultof cable installation operations that occur in the river will directly impact the Hudson River. All marine vessels will be equipped with spill control measures and staffed with trained personnel in the event of a spill. 4,0 OIL STORAGE OPERATIONS This section describes oil storage and oil-rontaining equipment at the site. The material and construction of each container is compatible with the material stored and conditions of storage. Individual portable containers (l.e., 55 gallon drums) are not depicted on the site plan, but locations where these portable containers are typically stored in significant quantities are identified. Oil loading and unloading procedures aredescribed in detail in section 5.0. COnstruction phase oil storage and containment will be limited to minimal quantities stored in temporary containers located within the designated staging area and to those oils associated with non transportation related, heavy construction equipment, hereafter referred to as "in-process use" oils. Details regarding the storage capacity, type of oil and othermaterials, and containment capacity for volumes of at least55 gallons that are present in tanks, containers, or various devices are provided in Table 4-1. If a release of oil were to occur from tanks, containers, or process equipment, the amount of material spilled would depend on the size of the container and the type of release. Total materials released could range from a few drips to approximately 1,000 gallons, and the maximum rate of flow could be the instantaneous (complete failure of the container or device) release of 1,000 gallons. Spills occurring during the construction of this Project have the potential to impact a surface water body (see section 3.0). Contractors will comply with the follOWing standards for the storage of oil: • Maintain copies of materials safety data sheets on-site. • All applicable state, local and federal regulations covering the transport, storage and handling ofoil. • Fuels and other controlled materials will be stored in designated areas. All such areas will be at a minimum, 100feet from any water body, watercourse, wetland or known spring or well. 4 H-18 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 • Above ground tanks will be equipped with secondary containment devioes (l.e., double walled fuel tanks). Oil will be kept in restricted access areas and kept separate from other construction activities. • All yards and storage areas shall be equipped with sufficient supplies of spill control and absorbent materials for the volumes present. • Spill control supplies will be clearly marked, readily accessible, and personnel will be instructed on their use prior to the initiation of construction. 4,1 Refuelina protocals 4.1.1 Land-Based Equipment Refueling of construction equipment on-site will occur on a staging area or directly in the construction area. Fuel oil will be brought onto the construction site as necessary. A permanent fueling station is not proposed at this time. If a temporary fueling station is required, a double walled refueling tank will be placed on site on top of an impenneable surface (le: concrete or pavement) to prevent discharged fuel from reaching a navigable water. The materials and construction of the temporary refueling tank will be compatible with the storage of fuel(s) dispensed (i.e., gasoline, diesel, etc.). The temporary refueling tank will be firmly secured into the substrate supported by an appropriate foundation to prevent settlement. Other oils associated with oil-containing construction equipment, such as lubricating oils and hydraulic oils, will also be brought onto the construction site as necessary or will be stored in containers within a fuel and oil storage building. The material and construction of each building will be compatible with respect to the material stored and ambient storage conditions. The contents of all tanks and containers of various oils Within this building will be kept at ambient temperature and pressure. In order to prevent vehicle departure before complete disconnect of fleXible or fixed transfer lines, the fuel delivery truck driver will remain with the refueling vehicle at all times during the fuel transfer process. Additionally, prior to filling and departure of any tank car or tank truck, the delivery truck driver shall notify appropriate site personnel so that the lowermost drain and all outlets of such vehicles will be closely examined to prevent liquid leakage while in transit. Instructions will be provided to bulk oil delivery truck drivers for loading/unloading procedures. 4,1,2 Marine Equipment It will not be necessary to refuel the barge that is in the river. However, equipment located on the barge may require refueling. In the event that refueling becomes necessary, a refueling barge would be sent to the barge in the river, and a refueling hose would be passed from the 5 H-19 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 refueling barge to the construction barge. Any operations refueling will be subject to US Coast Guard regulations. 4,2 In-process Use Oils In-process use oils associated with non-transportation related, heavy construction equipment and other oil-containing devices have the potential to be released as they maneuver and operate throughout the construction site. The proposed schedule for construction operations is detailed in the EM&CP for the Project. The nature and volume of oils contained within construction equipment are typical for construction operations of this scale and include diesel fuels, lubricating oils, and hydraulic oils. All heavy construction equipment will be equipped with spill response materials such as absorbents to contain material that may be inadvertently released. Temporary, construction-phase sheds or job boxes with spill response kits will be located in an area adjacent to the refueling station or other appropriate locations throughout the proposed project area. All heavy construction eqUipment supervisors will be adequately trained in emergency spill response procedures and familiar with this SPP document (see 5ection 8,0). Inspections of non-transportation related, heavy construction eqUipment are conducted at least weekly and during each visit to the refueling station for any leakage of oils. All observations are recorded in an inspection log (refer to the sample log contained in AppendixA). Table 4-1 summarizes exterior oil storage and oikontaining equipment at the site, and provides location, equipment capacity, the most likely route of exposure, and secondary containment, engineering controls, and pollution prevention strategy in case of a spill. 4,2.1 Cable Insta"ation The Cross Hudson Project includes the installation of one 345 kV AC generator lead, consisting of three SCFF cables. Each of the cables is filled with apprOXimately 1,000 gallons of dielectric fluid. During installation, the upland and submarine cable types must be spliced together in a Splicing Chamber. Splicing of the Cross Hudson Project cable takes place underground, in a controlled environment. The splicing is performed in the splicing chamber, which is a contained concrete vault. A minor quantity of dielectric fluid could be spilled, but would be contained within the splicing chamber. The environment around the splicing chamber is also controlled, usually with the use of a tent or tarp to cover the area. 6 H-20 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 Inspections of non-transportation related, marine construction equipment will be conducted at least weekly and during each visit to the refueling station for any leakage of oils. All observations are recorded in an inspection log (refer to the sample log contained in AppendiX A). Table 4-1 summarizes exterior oil storage and oil-containing equipment at the site, and provides location, equipment capacity, the most likely route of exposure, and secondary containment, engineering controls, and pollution prevention strategy in case of a spill. 5.0 LOADING/UNLOADING PROCEPURES Fueling operations at the site are handled by the Contractors, who are responsible for fuel deliveries for diesel, No. 2 fuel oil, and unleaded gasoline. All tanks are filled from tanker trucks. Personnel observing filling are required to verify that adequate tank capacity is available prior to unloading to minimize the likelihood of tank overfills. Personnel are provided with both formal and on the job training in all aspects of fuel deliveries. Cross Hudson employees have also received training in spill control measures and proper reporting procedures in the event of any equipment malfunction and/or spill. When refueling equipment during construction the follOWing standards will be applied: • Equipment refueled in yards shall be refueled in a clearly marked and designated refueling area; • Designated refueling areas will be located on impenneable surfaces to contain spilled oil, fuels or lubricants; • Care will be exercised at all times to prevent overfilling; • When refueling, all fuel trucks, portable drums and tanks will be inspected for leaks or signs of wear; and • All refueling trucks will carry spill containment materials, and the driver/operator will be trained in their use and responsible for their employ after spills. No refueling will be perfonned witllin 100 feet of any wetland, stream, known well or spring. The only exception to thls prohibition will be portable water pumps and barge fueling activities. 5.1 Bulk Fuel Transfer When fuel is transferred from a tank truck, the driver will park in the appropriate staging area. The fill connection for each tank is located witllin a secondary containment area and a spill bucket is placed beneath connections during loading operations. Should a transfer hose fail during the loading process, fuel would not be released from the tank since it is loaded into the top of tank, above the liquid level. If at any time a release oa:urs, transfer operations will be stopped immediately and spill response measureswill be impiemented. 7 H-2l Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 Thefollowing steps describe the delivery prooedures for bulk fuel: 1. Drivers delivering fuel must inform the appropriate Contractor of their presence on site. The Contractor will verify that adequate tank volume is available for the delivery. No unsdleduled fuel deliveries can be made to the facility. 2. The Contractor will assist the driver and oversee the delivery. 3. The driver mustpark the truck in the appropriate unloading area. 4. The driver mustinform the Contractor of the location of the emergency stop switch that will stopthe transfer pumpon the truck. 5. The handbrake must be set and the truck wheels are chocked to prevent movement of the vehicle prior to disconnecting hoses. 6. Drip pans must be placed beneath each ronnection or valve of the truck and under the fill ronnection. A spill box, rontainment, or permanent spill bucket is used to control any minor leaks from the check valve and fill pipe. 7. The driver must make the appropriate ronnections from the truck to the storage tank fill port, and the Contractor will monitorthe operation. 8. After the previous steps have been taken, the driver can transfer the fuel. During transfer, the driver andthe Contractor mustcarefully observe the truck and hose. 9. Upon rompletion of the transfer, the driver will ensure that the transfer hose is empty before disconnecting. If any fuel is spilled, cleanup will begin immediately. 10. Any fuel rollected in the drip pans will be transferred to the proper waste rontainers in the storage area. 11. The Contractor will ensure that the fill pipecap has been re-secured. 12. Only after allthe steps described above have been satisfactorily rompleted will the driver be allowed to movethe vehide and leave the site. 5,2 prum Transfers When materials are transported on-site using a forklift, either a drum attachment is used or containers are secured to pallets on the forklift to prevent the containers from falling during movement. If a barrel dolly is used, the operator will ensure that the barrel is compatible with the dolly and that the barrel is properly secured to the dolly. The following outlines delivery and transport procedures for small containers: 1. Containers are checked for damaged areas or signs of corrosion, If any is detected, the rontainercontents aretransferred to an appropriate rontainerand labeled prior to moving. 8 H-22 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 2. Cross Hudson personnel ensure that containers aresecurely closed prior to moving. 3. Containers are secured on forks or pallets when using a forklift or properly secured when using a dolly to prevent containers from falling during movement 6,0 INSPECTIONS AND RECORDS Inspection procedufes have been developed for oil storage areas to prevent or qUickly detect signs of oil leakage, equipment malfunction, structure deterioration, and depletion of spill control equipment If a repair or alteration will affectthe risk of discharge, additional tank evaluations will be considered. Key personnel at the site who are familiar with locations and type of equipment conduct periodic inspections of all oil containing equipment and storage containers included in this SPP. Other properly trained personnel may assist with inspections, asneeded. Inspections and maintenance procedures will be conducted at weekly intervals and after each precipitation event to evaluate storage areas for the presenoe of oil and to observe the integrity of the equipment. If storm water accumulates nearany of the oil storage areas, the storm water will be visually inspected for any evidenoe of sheen prior to removal. The observations of each inspection and any remedial action taken will be recorded in an inspection log. If there is no Visible sheen present on accumulated storm water, removal procedures will entail manually activated pumping of discharge into the site's drainage system. The presence of a visible sheen on the accumulated storm water is evidenoe of a spill and will trigger appropriate response actions. In addition to routine inspection of temporary fuel tanks and oil storage areas, inspections also review, and replenish if necessary, the contents of spill response kits located throughoutthe site. A copyof this SPP, including records of all inspections and tests, will be maintained on site. All records of visual inspections will include the follOWing information, where appropriate: • Date and time of inspection; • Typeof inspection (visual, hydrostatic, etc.); • Signature of the inspector; • Results of the inspection, including remedial actions necessary; • Remedial or preventative actions taken; and • Explanation of why remedial actions were not completed, if applicable. Z,O SECURITY Cross Hudson's Contractor will monitor conditions on the site during all working hours. Access to sensitive areas is controlled to prevent unauthorized entry. Theconstruction area is well lit at night, and lighting is 9 H-23 Spill Prevention Plan ENSR I AECOM Cross Hudson Project February 2008 adequate for the identification of spills and prevention of spills through vandalism. All oil- 8,0 PERSONNELTRAINING All personnel that might be involved in the discovery of and response to a release of oil at the site will be familiar with this SPP, the nature of oils contained on-site that could be released, and the location, use, and maintenance of site spill response equipment To protect human health and the environment, a training program will be conducted to ensure that spill response personnel understand the hazards associated with ali materials with the potential for release and applicable emergency response regulations. SUpervisory training (including that for Emergency responders) will be conducted to ensure that personnel responsible for implementing the activities described in this plan, or who are otherwise responsible for oil poliution control, are familiar with the components and goals of this plan. Personnel wili be trained as appropriate for their job duties, on good housekeeping measures, proper operation and maintenance of equipment, proper handling procedures for oil and waste oil, and procedures to foliow during an emergency. The purpose of the training is to ensure that discharges are prevented and spili response procedures are reviewed. Training may be provided in a formal dassroom type setting, as on-the-job training, or during safety meetings as appropriate. Spill response procedures and signs will be posted at the facility providing spill response equipment location. Furthermore, training sessions will be conducted after any release and response to a release has occurred. 9,0 EMERGENcy RESPONSE Ali spilis are to be reported to the Cross Hudson representative. Smali, contained spills wili be addressed by the Contractor. Large spills and those involving flammable material may require the assistance of outside agencies. The foliowing sections describe the emergency equipment maintained at the facility and the procedures the Contractor will take in the eventof a release of oil. 9.1 Emergency Equipment The Contractor will store absorbent materials (i.e., spill pads, socks, booms, etc.), empty 55ijallon drums, brooms, shovels, and personal protective equipment (PPE) on site to handle incidental spills. The spill response equipment is stored near construction equipment, on marine vessels, and in lockers throughout the construction site. Response personnel can qUickly access spill response equipment to facilitate qUick responses in the eventof a spill. On a monthly basis, the Contractor will to H-24 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 verify that there is adequate spill response equipment to mitigate incidental spills. Generally, oil spills greater than 55 gallons are handled by a licensed spill response and waste removal.contractor, Absorbent materials may be used to contain spills and prevent oil from reaching navigable waters. The Contractor may set up absorbent materials based on the direction of the oil flow and the volume of oil that is released. The Contractor will maintain an adequate supply of on-site to control spills of hazardous materials, which may be used during construction activities, including: • Sorbents, including pillows, wipe sheets and sawdust. • Commercially available spill kits (or equivalent) to handle spillsof varying sizes. • Shovels or small backhoes for the excavation of contaminated soils or materials. • Drums, barrels and other temporary storage containers for the clean up and transport of contaminated materials. • Absorbent pads for placement understatic machinery large enough to handle a complete loss of engine oil or hydraulic fluid. • Small sorbent kits for all vehicles and machinery. In addition, the Contractor must stock the follOWing equipment when conducting waterborne activities: • Rapid deployment fire proof/fire resistant oil containment floats and booms. The minimum length of booms should be sufficient to surround the work area and vessels. All booms will conform to USDOT and US Coast Guard requirements. • Oil removal or skimming equipment should be on hand or on call, inclUding oJephilic and hydrophobic absorbent booms or mats and/or mechanical skimmers. • sampling equjprnent of sufficientamounts to enable 24- hour monitoring if necessary. When conducting waterborne activities, the Contractor must also stockor have access to dispersants, dispersant delivery platforms (i.e., aerial or marine), loading facilities, communications, etc. A list of spill response equipment is provided in Appendix A of the SPP. 9.2 Emergency Procedures The responsibility for control and dean up of small 011 spills lies primarily with the COntractor, which will employ properly trained personnel to support oil spill dean up operations as required. If a spill presents an immediate hazard to personnel safety or the environment or is too large and cannot be handled by on-see personnel, spill response contractors may becontacted by the Cross Hudson representative. II H-25 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 • The Doss Hudson representative will coordinare any and all decision making for spill containment and removal with Stare and Federal authorities (listed in Table1-1). If a release of oil from a tank or containeroccurs, tne following actions will be taken: 1. The Contractor will stop oil transfer operations or container movement (if applicable) until the release is stopped andoil spilldebris material is removed. 2. The first person discovering any release of oil is responsible for securing the area and notifying the Doss Hudson representative to determine tne appropriate course of action for containment and removal of tne oil and waste material, If necessary, a licensed contractor maybe contacted. 3. Other Emergency Response Personnel (listed in Table 1-1) will be contacted as necessary. 4. The Cross Hudson representative will function as Incident Commander until relieved by a representative of a response agency) and will: • Notifythe Contractor of hazards caused by the spill; • Take appropriate measures to cope with tne emergency; and • Order staff evacuation, if necessary (in conformance witl1 tne procedures outlined in tne emergency evacuation plan). Evacuations of parties other tnan tne contractor's own personnel will be determmed by local authorities. 5. TheContractor is responsible for securing tne incident scene and directing traffic awayfrom the area until relieved by the appropriate emergency personnel. 6. If derermined to be safe, trained personnel will take immediare steps to stop tne discharge and begin clean-up operations using mechanical methods (l.e., shovels, brooms, absorbent materials, etc.), Procedures for containment and clean upof oil spills include: • Removal of all sources of ignition from the spillarea; • Donning of appropriate PPE (i.e., rubber boots andworkgloves); • Focusing effortson preventing the oil from spreading from tne area into drainsor warerways; • Applying absorbent materials for NO.2fuel oil, diesel fuel, gasoline, dielectric fluid, etc.; • Construction of containment structures witl1 absorbent booms, and other absorbent materials, such as sand or dirt; • Transferring spilled materiels into appropriare containers, such as drums or plastic bags using non-sparking shovels, pumps, or brooms; and 12 H-26 Spill Prevention Plan ENSR IAECOM Cross Hudson Project February 2008 • Consideration of appropriate alternatives for large spills, sum as contracting a spill cleanup contractor. 7. If a spill is immediately hazardous (i.e., gasoline spill that poses a fire or explosion hazard), and cannot be handled by on-site personnel, or has entered the environment, the Cross Hudson representative will contact a spill response contractor. 8. The Cross Hudson representative will initiate other clean-up activities and monitoring, if required by applicable regulatory authorities. 9. The Cross Hudson representative will submit written reports to the required authorities, where applicable. 10. The Cross Hudson representative will update authorities with new information as it becomes available, if necessary. 11. The Cross Hudson representative will document spill response activities and maintain records of all spill notifications and responses on site. Oil-eontaining debris resulting from oil releases to the environment (land or water) and contaminated spill response materials will be retained for characterization in the appropriate designated area pending disposal. Disposal will be performed in accordance with all applicable hazardous waste and/or solid waste regulations. If the debris is determined to be non-hazardous, it will be stored on site pending disposal at a facility licensed to accept such waste. If the waste is determined to be hazardous, it will be stored and disposed of with other hazardous waste generated at the site. Records, including manifests, documenting the date the contaminated debris were removed from the site and the location of ultimate disposal will be retained on site and/or submitted to authorities as necessary and in accordance with applicable regulatory requirements. The Emergency Contact Ust (Table 1-1) contains contact information in case of any spill related emergency. 10.0 NOTIFICATIONS This section details the response and notification procedures that are to be implemented in the event of an oil spill at the site that has contacted or threatens to contact environmental receptors sum as exposed soil, surface water, storm drains, or any entry point to the local sanitary sewerage system. When personnel have observed a release of oil of any volume, the Cross Hudson representative will be notified. The observer of the spill will communicate the location of the release, the material released, the volume of material released, and whether any amount has reached floor drains, storm drains, or exposed soil. The Cross Hudson representative will be responsible for determining what external notifications are required and for making all external notifications to appropriate regulatory agencies in the event of a spill or other emergency. 13 H-27 Spill Prevention Plan ENSR I AECOM Cross Hudson Project February 2008 The procedures for notifications to the appropriate regulatory agencies in the event of a spill are described below. 10.1 Ora' Notifications At a minimum, the Contractor shall notify the Cross Hudson representative in the event of an oil discharge, who will instruct personnel with regard to further notification(s).

Facilities that meet certain criteria are considered to pose substantial harm to the environment. A checklist of criteria for substantial harm is provided as part of the regulation and was used to determine that the construction of the Manhattan Segment does not meet the requirements for posing substantial harm to the environment. The Certification of the Applicability of the Substantial Harm Criteria is located in AppendiX C. 12.0 PLAN AMENDMENTS 12.1 plan Review . Plan reviews are required as follows: • At a minimum, once every five years from the date on which the plan is first approved; • If the plan is shown to be deficient in controlling oil spills; • To clarify the measures that were taken to remedy an oil spill, where the plan is not considered to be deficient in controlling the oil spill; and • When there is a change in design, construction, operation, or maintenance that materially affects the potential to dischargeoil or pollutants into or upon waters of the state. The plan must be updated as needed to include more effective prevention and control technologies if the technology has been field proven at the time of the review and will significantly reduce the likelihood of 'a discharge. Each review must be documented in the log provided in the front of this plan, or an equivalent form, whether or not amendments to the plan are required. 12.2 Professional Engineer (PEl certification PE certification is required for technical amendments that require the application of good engineering practice. Non-technical changes (i.e., those that do not affect the oil storage operations at the facility) that do not require PE certification include: • Changes to contact information (names, titles, and phone numbers); • More stringent requirements for storm water discharges associated with NPDES rules that are not addressed by and do not impact the SPP; 16 H-30 Spill Prevention Plan ENSR I AECOM Cross Hudson Project February 2008 • Product changes if the new procluct is compatible with conditions in the existing tank and secondary containment; and • Other changes that do not materially change the potential to discharge oil. 13.0 ENGINEERING DEFICIENCIES Provided that the Contractor operates in accordance with this SPP, there are no engineering defICiencies relative to 40 CFR 112. The Contractor must continue to ensure that the measures desaibed in this SPP (e.g., inspections, training, security, housekeeping, etc.) are implemented. 17 H-31 H-32 CROSS HUDSON PROJECT SPILL PREVENTION PLAN APPENDIX A Sample Inspection and Reporting Forms and Spill Response Equipment H-33 H-34 Appendix A Oil SlDrageArea I~ Allreferences to CDI1Iainer aremeantto indude alltanks and CDI1Iainers storing~ 55gallons ctoil.

Concrete is inherently a cheap material to produce and Pre-assembledpipespool bridge can be readily adapted. When properly designed the durability of concrete products in a marine environment out ~erlorms steel and requires no additional treatments such as cathodic protection or coatings. Used as gravity structures, no additional installation measures such as piling or ballasting are required to provide stability. It is our policy to provide the client with a complete package by providing cost effective solutions which consider aspects such ---. as lift limitations, ease of positioning on the sea bed, transportation and optimised use of the installation vessel. Design aspects undertaken include: Flowline crossing bridge Stability calculations to optimise mattress sizing for site specific environmental loading. Calculations and detailed design for trawlboard and dropped object resistance. Mattresses, covers, pipe supports, ramps, bridge crossings, anchor blocks etc. can all be designed to site specific requirements. Foundation design for pipe support systems. Scour prevention and remedial design studies. Impactresistant covers for expansion spools Innovative designs using reinforced and pre-stressed concrete for subsea applications.

No steel members (nor any other metals) are used in the blocks - this avoids dissimilar metal corrosion problems that have arisen in the offshore oil and gas industry from the use of slag in rock dumps. The Frond Line attachment points are moulded into the concrete base blocks. FROND FLEXIFORM CONCRETE MATTRESS The "Frond Flexlfonn" Mattress combines all the features of both a flexible concrete mattress and a buoyant frond scour control mat in one: and in particular it offers the following benefits: »installation is simple and swift, and it provides both instant protection and immediate hold down; ~ the creation of long term fibre reinforced, consolidated and vibration compacted sediment bank build up over the mattress SUbstantially adds to the degree of protection afforded and provides an exceptional reduction in scour potential close to structures: »it provides scour protection for an area somewhat greater than the actual area covered by the mattress: ).- the individually profiled concrete segments provide a high degree of flexibility in two planes and allow for a complete protection of subsea structures and pipelines and offer a linked flexible foundation to ensure that load is spread evenly over an area; and }.> the fronds prevent edge scour and also halt internecine block (or rock) scour, this eliminates any requirement for the use of geotextile filter screens under a Frond Flexiform mattress. The submerged weight of the mattress on first installation will increase as the scour control system creates a fibre reinforced bank over the base mattress. The rate of build up and size of such bank vanes from site to site. The build up of the material bank within the Frond Flexiform mattress is non-linear. The 1.25m high fronds create the greatest viscous drag when first deployed and the initial 200mm to 300mm of mat/mattress inf\ll occurs quickly in normal tidal conditions given the sort of sediment sizes at most offshore sites. As the material bank forms, the exposed frond length is reduced, the mat creates less viscous drag and the rate of formation of the material bank slows until a steady state is reached. The sediment bank created is considerably more stable and more dense than the natural surrounding seabed: many surveys have conflrmed that it is considerably consolidated by the vibratory movement ot fronds during the sedimentary period and once in place it is permanently reinforced by the frond material. Any sediment bank so formed extends out from the frond area to cover the sides of the base mattress extending out in descending curve to seabed level for a distance slightly greater that the height of the formed bank - the final shape of such a "curve" depends upon the coefficient of friction of the seabed particles. SBM-DTS-031 Rev 2 Page 1 013 15 ~~s. ~~ /t,,~ Offshore/Onshore Solutions FROND FLEXIFORM CONCRETE MATTRESS SEDIMENT BANK PROJECTION For offshore sites after some 20 to 45 days a significant. compacted and solid sediment bed will be in place and a height of not less than 450mm is normal: the final height of bank with a frond height of 1,250mm should should safely exceed 900mm in height after some 40 to 75 days. The formation of such a sediment bank over the Mattress provides submerged weigh or "held down". A typical SUbmerged weight of sand particles is 819.5kglm3, but the range is large thus the submerged weight of the fibre reinforced material bank can vary. For a 5.0m x 3.0m Frond area this should be: • after 20 days: in the range 6.67 tonnes to 5.5 tonnes - this is additional to the base mattress' concrete block weight (with 150mm base blocks = 2.28l submerged weight and with 300mm base blocks =4.18t submerged weight). • after 40 to 75 days: in the range 15.0 tonnes 11.08 tonnes + base mattress' concrete block submerged weight. BUOYANT FROND MATERIAL UV stabilised Polypropylene. Fully tested" Chemically Resistant". Specific gravity 0.908 and 0.92. Full fibrillated and with profiled film. FROND LENGTH & ATIACHMENT Buoyant Fronds are attached to Mattress in successive continuous rows providing substantial and unbroken overlap of fronds to those in the neighbouring rows. Frond clumps are NEVER used. Frond Length (height when deployed) of the lines of buoyant frond material is 1250mm. In riverine (and other special situations) lesser frond heights allied to a proportionate increase in frond density (spacing) in the frond rows may be used. A "Safe Net" frond release is provided for diver and ROV safety. STANDARD BLOCK THICKNESS 150mm, 300mm, and 450mm. STANDARD BLOCK DENSITY 2.4 Tonnes / Cubic Metre.

A typical SUbmergedweight of sand particles is 819.Skg I rna. but the range is large thus the submerged weight of the fibre reinforced material bank can vary. For a 6m x 4m mattress this should be in the range is large thus the submerged weight of the fibre reinforced material bank can vary. For a 6m x 4m mattress this should be in the range 23.9 tonnes to 19.9 tonnes • this is additional to the concrete weight which with a 150mm thick mattress at standard density would be 3.7 tonnes giving a total submerged hold down of 27.6 to 23.6 tonnes.
