NOTES 1 - TCEQ Tier I Residential Soil PCLs, 0.5 acre source – GW Soil Ing.2 - TCEQ Chapter 350 -Texas-Specific Soil Background Concentrations 3 - TPH testing will be used to screen for PAHs using method TCEQ-1005. If the laboratory reports any detection of hydrocarbons in the carbon range greater than nC12, then the sample with the highest concentration of hydrocarbons in the > nC12 range must be analyzed for PAHs. The PAH results will be compared to the PAH results listed above.

Please read the following instructions. If you have any questions, please contact the SMP Manager at (210) 207-3402 or the Environmental Stewardship Division at (210) 207-3862

No soil originating on airport property shall leave the airport without SMP Manager approval.

No soils other than those required by engineer’s specifications and not available through

the SAAS stockpile program shall be imported onto the airport without SMP Manager approval.

All trucks using public roadways within airport property and transporting erodable

materials such as soil, sand, gravel, rock, concrete chunks, etc. shall be in good condition and shall be in compliance with TXDOT rules and regulations.

Soils disturbed by excavation or drilling shall be observed for visual and olfactory

evidence of contamination. That means if you see or smell anything unusual, immediately contact the SMP Manager. If evidence of contamination is encountered through visual or olfactory senses or by required instrument screening, the contractor shall immediately notify the SMP Manager and then store the contaminated soil in a manner to protect from precipitation, generally by placing the soil on a layer of plastic and cover with a layer of plastic.

Excess uncontaminated soils should not remain as soil piles on the project site any longer

than necessary. Should there be a need to store excess soils on the project site, the location of any temporary stockpiles should be noted in the Storm Water Pollution Prevention Plan (SWPPP). Any stockpiles or areas not in use for a period of 21 calendar days are to be stabilized by some means such as covering, surrounding by silt fence, hay logs and growth of grass to minimize erosion and sediment transport potential. “Clean” soil stockpiles are not to be contaminated in any way with construction debris, or spills of fuel, oil, solvents, chemicals or other waste materials.

All clean excess soils shall be transported to a SAAS Soil Stockpile area. The stockpile

area does not accept loads with trash, pipe pieces, rebar, concrete chunks or other types of construction debris. Rejected loads are the responsibility of the Project Manager to correct by removal of debris, etc. Small amounts of excess soil such as placing post holes may have an option to spread soil at the site as long as it is evenly and very thinly spread over a wide grassy area and is not in danger of washing into a nearby storm drain or body of water during a rain event. Soils segregated due to any evidence of contamination shall be managed in accordance with SAAS’s Soil Management Plan.

Entry to SAAS Stockpiles is controlled access only. Arrangement must be made with the

SMP Manager for gate/stockpile site access. Other arrangements may be made to transport uncontaminated soil to other project sites or locations on the airport, but shall

not be done without prior approval of the SMP Manager and will be documented through the use of the SMP Manager Authorization Form.

Any loads dumped by truck drivers either containing unwanted materials or debris, in an

unapproved location or without the Project Manager’s prior approval shall be the responsibility of the Project Manager to arrange for removal and/or mitigation.
