Provide protection measures around the excavation area to prevent water runoff and to contain the soil within the excavation area.

b. Perform excavation around the perimeter of the tank to limit the amount of potentially petroleum contaminated soil that could be mixed with previously uncontaminated soil. Segregate petroleum contaminated soil in separate stockpiles.

c. Maintain an excavation around the tank of sufficient size to allow workers ample room to complete the work, but also protect the workers from sliding or cave-ins. Install sheeting, bracing, or shoring in the

Demolish Hospital Fort Riley, Kansas

02 65 00 - 11 absence of adequate side slopes if there is a need for workers to enter the excavated area. Divert surface water to prevent direct entry into the excavation.

d. Dewatering of the excavation may require a discharge permit by the

State and shall be limited to allow adequate access to the tank and piping, to assure a safe excavation, and to ensure that compaction and moisture requirements are met during backfilling. Dewatering may result in the production of petroleum contaminated water and/or free product. Recover free product from the groundwater only as part of necessary dewatering.

e. Collect and test water generated by dewatering during excavation required for removal of tanks or piping, surface water collected in open excavation, or water used for washing equipment or existing concrete or bituminous surfaces, in accordance with EPA 530-R-97-007, EPA 600/4-79/020, EPA SW-846 and state or locally required analyses.

3.7.3 Temporary Containment of Excavated Soil

Provide temporary containment area near the excavated area. Cover containment area with three layers of 6 mil polyethylene sheeting. Place excavated soil on the impervious barrier and cover with 6 mil polyethylene sheeting. Provide straw bale berm around the outer limits of the containment area and cover with polyethylene sheets. Secure edges of sheets to keep the polyethylene sheeting in place.

3.7.4 Piping Excavation

Perform excavation as necessary to remove tank piping and ancillary equipment in accordance with paragraphs: Shoring, Tank Excavation, and Open Excavations.

3.7.5 Open Excavations

Secure open excavations and stockpile areas while awaiting confirmation test results from the soil beneath the tank. Backfill the excavation as soon as possible after tank and contaminated soil removals have been completed and confirmation samples have been taken. Divert surface water around excavations to prevent water from directly entering into the excavation.

3.7.6 Hidden Structures

During excavation activities, if asphalt pavement, concrete slabs, or other hidden structures are encountered, remove and wash with high pressure water cleaning equipment. Remove and dispose of the pavement, concrete, and other structures as specified in Section 02 41 00 DEMOLITION.

3.7.7 Stockpiles

Uncontaminated excavated soil and petroleum contaminated soil, that is not a state-regulated hazardous waste, that is below residential levels for TPH shall be stockpiled and used for backfill in the tank excavation prior to using borrow material and disposed of in the area designated on the drawings. Prior to reuse, soil must be tested at a rate of on sample per 100 CY and results shall be below the residential levels for TPH. Excavated material that is regulated by the state as a hazardousspecial waste which

02 65 00 - 12 is visibly stained for which real time vapor monitoring instrument readings exceed for volatile and possibly semi-volatile hydrocarbons depending on the performance criteria for the field screening method and which has an obvious petroleum odor or as required by the State of Kansas or implementing agency is considered contaminated. Place in containers such as drums, roll-offs or dumpsters for sampling in accordance with paragraph Stockpiled Material Sampling. Separately stockpile uncontaminated soil from the contaminated soil, a safe distance away from, but adjacent to, the excavation. Place allowable stockpiles of contaminated soil on an impermeable geomembrane plastic sheeting a minimum of 3 layers, each 6 mils thick, covered with a 6 mils sheet of geomembrane plastic sheeting as specified. Place the geomembrane plastic sheeting to prevent the stockpiled soil from coming into contact with surface water run-off. Locate the geomembrane plastic sheeting cover to prevent rain or surface water from coming into contact with the contaminated soil, as well as limit the escape of the volatile constituents in the stockpile.

3.8 REMOVAL OF PIPING, ANCILLARY EQUIPMENT, AND TANK

Disconnect all piping and ancillary equipment from the tank. Remove the piping completely (interior and exterior of the tank) from the exterior surface of the tank, cap and abandon in place. Cap all tank ancillary equipment and piping connections, except those connections necessary to inert the tank within the excavation zone. Clean the piping exterior and ancillary equipment to remove all soil and inspect for signs of corrosion and leakage. Ensure no spillage of the piping contents occurs, as specified in the Work Plan, and as required in paragraph SPILLS. If the soil under and around the tank pad is contaminated, remove the tank pad and dispose of offsite at an approved hazardous waste facility.

3.8.2 Tank

Remove the tank from the excavation and clean the exterior to remove all soil and inspect for signs of corrosion, structural damage, or leakage.

Use only non-sparking type materials or equipment which comes into contact with the tank, or in the vicinity of the excavation such as shovels, slings and tools. After removal from the excavation, place the tank on a level surface adjacent to the tank excavation at an approved location and secure it with wood blocks to prevent movement.

3.8.3 Contaminated Soil, Tank and Piping Excavation Examination

a. After the tank has been removed from the ground, examine and test the adjacent and underlying soil for any evidence of leakage. Visually inspect the soil for staining after removal of all obviously contaminated soil, then screen for the presence of volatile and/or semi-volatile contamination using a real time vapor monitoring instrument and or immunoassay field kits.

b. If tank is 20 feet or less in length, take two samples. Take each sample 2 feet from each end of the tank and 2 feet below the bottom of the excavation.

c. If the tank is greater than 20 feet, take three samples. Take two samples 2 feet from each end of the tank and 2 feet below the bottom of the excavation. Take a third sample from the middle of the tank area and 2 feet below the bottom of the excavation.

Demolish Hospital Fort Riley, Kansas

02 65 00 - 13

d. Analyze samples for TPH-LRH, TPH-MRH, and TPH-HRH. It is recommended that residential clean up values be used. If results exceed residential cleanup values, additional contaminated soil shall be excavated and additional confirmatory sampling shall be performed until residential cleanup values are achieved. Furnish results to the Contracting Officer's Representative within 24 hours after the results are obtained. Along with the results furnish a sketch showing underground tank, sampling location, and extent of excavations.

e. Transport offsite for disposal. Petroleum contaminated soil not regulated by the state as hazardous waste. Stockpile contaminated soil or suspected contaminated soil, or, if the site is a RCRA-designated CAMU, containerized until further disposition. Transport petroleum contaminated soil and dispose of as special waste at a facility permitted to accept the waste.

f. The State of Kansas inspector will determine the extent of the contaminated soil to be removed from each site. Report any evidence indicating that the amount of contaminated soil may exceed the individual site limit specifiedestimated contract quantity, to the Installation's Environmental Coordinator Contracting Officer’s Representative the same day it is discovered. If minimal additional excavation is required, the Contracting Officer's Representative may allow the Contractor to proceed. If extensive contamination is encountered, sample the excavation and backfill in accordance with paragraph BACKFILLING.

g. After the known contaminated soil is removed, sample and analyze the
