<br />The following represents minimum sampling criterion required for closure compliance. Soil samples collected shall be
<br />representative of native soils beneath the tank's invert (tank's bottom) at,a collection depth not to exceed 2 - 4 feet. If
<br />contamination is documented during closure, an Unauthorized Release Notification must be completed and submitted within five
<br />(5) working days pursuant to California Health & Safety Code, Section 25295.
<br />Notes:
<br />1. EPA Method 82606 analyses must include all analytes listed in the method plus fuel oxygenates methyl -
<br />tertiary -butyl ether (MTBE), diisopropyl ether (DIPE), ethyl -tertiary -butyl ether (EtBE), tertiary -amyl -methyl
<br />ether (TAME), tertiary -butanol (TBA), methanol and ethanol and fuel additives 1,2-dichloroethane (1,2 -DCA)
<br />and ethylene dibromide (EDB or 1,2-dibromoethane).
<br />2. If pentachlorophenol (PCP) is identified, analyze the soil and/or water sample for dioxins and furans by EPA
<br />Method 8290 and pesticides by EPA Method 8081 A.
<br />3. METALS ICAP or AA Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption
<br />Spectrometry 7000. Metals: Cadmium, Chromium III and VI, Lead, Zinc and Nickel.
<br />4. Non-proprietary, performance based analytical methods may be used with approval of Regional Board staff.
