1-3 Background Information:

The tanks range in size from 550 gallons to 1,000-gallons and have been used for the storage of residential heating oil at both historic and non-historic structures in the park. Currently the tanks are not being used, and have been inactive for an extended period of time. Although there is no evidence of leaking, the tanks are in excess of 30 years of age and may have the potential for failure resulting in a release of petroleum product to the environment. Removing these tanks will eliminate the potential for a fuel release to the environment, and completion of this project will demonstrate compliance with NPS policy for fuel storage tank management. Specific locations with tank sizes as follows:

· WEEC Dorm (Perrini) – 1,000 gallon: The tank is located behind of the side of the dormitory. It contains 27 inches of heating oil/sludge, no water.

· WEEC Classroom (Perrini) – 1,000 gallon: Tank is located behind the building about 25 feet away from the building. It contains 40 inches of heating oil/sludge, no water. There are no underground tanks immediately adjacent to the building even though 2 vent pipes still exist next to the building. The underground tank immediately adjacent to the building was removed during an earlier tank removal project.

· Nadler Caretaker – 550 gallon: The tank is located behind the building next to the basement entrance. It contains 33 inches of heating oil/sludge, no water.

· Zipser (Abraham Van Campen) – 550 gallon: Tank located on side of the house next to the main road. It contains 8 inches of heating oil and 2 inches of water. Due to a missing fill cap, water may have entered the tank through the fill pipe.

· Miller Farm House basement foundation – (2) 275 gallon aboveground tanks. These tanks are manifolded together. The tanks are empty with no detectable product. This site is located directly across the road from the Zipser location.

· Cliff Park – Garden Cottage – 1,000 gallon: The tank is located behind the building. It contains 5 inches of heating oil/sludge, no water.

· Cliff Park Superintendent’s House – 1,000 gallon: The tank is located on the south side of the building. It contains 4 inches of heating oil/sludge, no water.

· Travis A – 550 gallon: The tank is next to the building in the parking lot. Contents are unknown. Unable to measure due to 90 degree turn in fill pipe.

· Minisink Reformed Church – 550 gallon: The tank is located under an asphalt pad between the church and the attached building. It contains 25 inches of heating oil/sludge, no water. A section of the asphalt pad shall be cut and removed to gain access to the tank.

PART 2: TASKS

2-1 Site Preparation for Tank Removal:

Prior to beginning the UST removal activities the contractor shall ensure that the work area has been secured to prevent unauthorized entry to the work area by pedestrians or vehicular traffic, that all overhead and/or underground utilities have been located and marked, and all electrical equipment servicing the system has been deactivated. Prior to the start of work, the contractor shall determine the location of underground utilities and perform work in such a manner which will avoid possible damage, including hand excavation as required to minimize possibility of damage to underground utilities. Any underground utilities damaged by the contractor shall be repaired at no additional cost to the Government.

For the tank at the Minisink Reformed Church, the contractor shall excavate an area of the asphalt paved area by first cutting with an asphalt saw. The asphalt to be removed shall be of sufficient size to adequately remove the tank located underneath the asphalt paved area. Care should be taken not to damage the surrounding asphalt. The contractor shall be responsible for replacing any damaged asphalt, but the cutout section of asphalt is not required to be replaced.

2-2 Tank Preparation for Removal:

The contractor shall remove the remaining liquid/sludge in the tank using an explosion proof or air-driven pump. Where applicable, the tanks shall be purged to remove explosive vapors by utilizing an inert gas such as carbon dioxide or nitrogen, solid carbon dioxide (dry ice) or an educer-type air mover, and the tank atmosphere and the excavation area shall be regularly tested for flammable or combustible vapor concentrations until the tank is removed from both the excavation and the site.

2-3 Tank Excavation and Removal:

The work of this section includes excavation of the underground fuel tanks and fuel lines. After any hazardous vapors have been removed, the vent pipe removed, all holes plugged and all electrical and piping disconnected, the contractor shall excavate the ground on both sides of the tank in order to access the tank for cleaning. Excavated soil shall be monitored visually and with field screening equipment for the detection of petroleum contamination. Excavated soil with evidence of petroleum contamination shall be piled separately on polyethylene sheeting and bermed to prevent runoff. Stockpiled soil shall also be covered with polyethylene sheeting and bermed to reduce contamination from runoff. The tank shall be cut open and cleaned before it is removed from the excavation unless otherwise indicated by uncontrolled safety factors. Sludge bottoms shall be placed in drums for proper disposal in accordance with Pennsylvania/New Jersey Hazardous Waste or Residual Waste regulations as applicable. The equipment used to remove the tank from the excavation shall be of the proper size and lifting capacity to safely remove the tank. If removal of the tank threatens the stability of the structure foundation, the tank shall be closed in place in accordance with industry standards. All liquids and sludges shall be removed prior to in closure in place, and soil samples shall be taken under the tank.

Because of this historic nature of these structures, the contractor shall provide an archeological monitor to examine excavated materials during all soil removal activities. The archeological monitor will work directly under the supervision of a qualified archeologist. All excavations must be conducted with the designated archeological monitor on-site and directly observing. Any excavation without direct, professional archeological supervision will be considered a violation of the Archeological Resources Protection Act (ARPA), and will subject both the excavation's authorizers and the contractor to the civil and criminal provisions of ARPA. The archeological monitor will control the location and pace of soil removal and must halt excavations if intact archeological features or pre-1910 period artifacts are discovered. Soil removal will cease until an NPS archeologist can evaluate the uncovered features and/or artifacts on-site. The contractor (or the contractor's archeological monitor) shall notify the COR and park Cultural Resource Manager (570-296-6952) within 1/2 hour (30 minutes) if any features or artifacts of historical or archaeological significance are discovered.

If artifacts or buried archaeological features are discovered during excavation and before work is resumed the monitor shall photo document and record the nature of the discovery by using scaled photography, detailed hand drawn field illustrations representing a plan view and profile documentation of features where appropriate and narrative field observations of disturbed features and or artifacts. The artifacts will then be reinterred as appropriate. Then the recorded discoveries will documented in the final project monitoring report along with copies of the field notes. Both the archeologist and the archeological monitor should submit their resumes with the Cultural Resource Manager of DEWA prior to the project commencement. At a very minimum the archeologist supervising the archeological monitor must meet Secretary of Interior standards as an archeologist and must oversee monitoring, excavation, and subsequent report writing to NPS Directors Order 28 and NPS-28, and NPS DO-24 and NPS Museum Handbook standards, and professional qualification standards as listed in the Code of Federal Regulations, 36 CFR Part 61. The archeologist will need to request an accession number and catalog number from the DEWA curator prior to the initiation of soil removal so that all paperwork and photographs are properly accounted for.

The work of this section also includes the removal of the two 275 gallon tanks from the basement foundation of the former Miller farm house. The house was destroyed by fire several years ago. The tanks are located in the remnants of the foundation of the former house. They should be carefully lifted up to clear what remains of the stonewall foundation. The piping should also be removed with care and minimal impact to the foundation walls.

There is no evidence that the soil has been impacted by a petroleum product release. However, the archeological monitor shall take appropriate personal protection precautions during the excavation and monitoring activities.

2-4 Soil Testing/Site Assessment:

After the tank and piping has been removed, the contractor shall visually inspect the soil and field test the soil for signs of fuel oil contamination. If there are no obvious signs of soil contamination, the contractor shall proceed with confirmatory exit soil sampling and analytical testing by a qualified laboratory utilizing acceptable QA/QC protocol. Two (2) samples shall be taken for each underground tank; one sample below the below the bottom of the tank directly below the fill connection and one sample below the bottom of the tank directly below the product.

If contaminated soil is encountered, the contractor shall determine whether the contamination is localized contamination or extensive contamination. Localized contamination is defined as contamination that does not extend more than three feet beyond the tank system in any direction and does not impact water in the excavation. If the contamination is determined to be localized the contractor shall excavate the contaminated soils and proceed with confirmatory exit sampling. If extensive contamination is encountered, the contractor shall stop work immediately and notify the contracting officer and await further instructions.

Localized contaminated soil shall be excavated until field screen measurements indicate levels below the clean-up standards for contaminated soil. All contaminated soil shall be segregated form soils not suspected to be contaminated by visual observation and field screening the soil as it is excavated. Sampling shall be conducted for both the “presumably contaminated” and the “presumably uncontaminated” soil pile. Stock piled soil shall be placed on and covered with 6 ml polyethylene sheeting.

2-5 Site Restoration:

Any and all disturbed areas should be seeded with park approved native mix and mulched with weed-free straw. The impacted area shall be graded as uniformly as possible. Any and all disturbed areas in the execution of this contract shall be fully restored to original condition including all grading, seeding and mulching with Park-approved non-native tall fescue seed mixture. Perennial ryegrass is not permitted. The excavation areas shall be backfilled using certified clean weed free fill compacted in 12-inch layers.

The contractor shall be responsible for the repair, replacement, correction and/or mitigation of any damage caused or resulting from the contractor’s work activities.

2-6 Erosion/Sediment Control:

The contractor shall minimize the extent of the disturbed area throughout the duration of the work. The contractor shall provide and implement a best management practices (BMP) plan in accordance with Pennsylvania Department of Environmental Protection (PADEP) describing the measures to be used to prevent runoff into waterways (straw bales, silt socks, mulch, dikes, soil binders, etc.). Any E & S blankets should be 100% organic (jute); no photodegradable synthetics. The plan should include a site sketch with staging areas and locations used for storing backfill and contaminated soil (if needed). Stockpiled soil shall be covered with polyethylene sheeting and bermed to reduce contamination from runoff, and contaminated soil shall be contained on polyethylene sheeting, covered with sheeting and bermed to prevent runoff. The E & S plan shall be submitted to the park prior to the start of any work.

2-7 Waste Disposal:

The contractor shall be responsible for disposal of all wastes produced as a result of this project including any residual or hazardous waste, and all wastes shall be disposed off park property at waste disposal facilities approved for such waste. The steel tanks shall be disposed of at an approved recycling facility. Heating oil sludge wastes shall be disposed of in accordance with the PADEP/NJDEP residual waste regulations and/or recycled if possible. Heating contaminated soil shall be disposed of in accordance with PADEP/NJDEP standards for disposal of heating oil contaminated soil. All wastes resulting from the work of this contract shall be transported in accordance with applicable transportation hauling regulations or restrictions. Where applicable the contractor shall be responsible for completing hazardous waste manifests, non-hazardous waste manifests and certificates of disposal, and shall ensure that the required documents are submitted to the disposal facilities and regulatory agencies.

2-8 Submittals:

The contractor shall submit a site specific safety plan prior to the preconstruction meeting and shall be approved by the NPS prior to the start of any work activities.

The contractor shall provide a final project report in hard copy and CD format to the National Park Service to include a detailed description of the project, certificates of disposal, waste manifests, laboratory reports and any other pertinent documentation. Final report shall be submitted within 30 days after the project has been completed.
