<br />eCFR :: 40 CFR Part 761 Subpart G — PCB Spill Cleanup Policy
<br />Requirements for decontaminating spills in other restricted access areas. Spills which occur in restricted access locations other
<br />than outdoor electrical substations, as defined under § 761.123, shall be decontaminated in accordance with paragraphs (c)(3) (i)
<br />through (v) of this section. Conformance to the cleanup standards in paragraphs (c)(3) (i) through (v) of this section shall be verified
<br />by postcleanup sampling as specified under § 761.130. At such times as restricted access areas other than outdoor electrical
<br />substations are converted to another use, the spill site shall be cleaned up to the nonrestricted access area requirements of
<br />paragraph (c)(4) of this section.
<br />High-contact solid surfaces, as defined under § 761.163 shall be cleaned to 10 pg/100 cm 2 (as measured by standard wipe
<br />tests).
<br />Low-contact, indoor, impervious solid surfaces will be decontaminated to 10 pg/100 cm 2.
<br />At the option of the responsible party, low-contact, indoor, nonimpervious surfaces will be cleaned either to 10 pg/100 cm 2 or
<br />to 100 pg/100 cm2 and encapsulated. The Regional Administrator, however, retains the authority to disallow the encapsulation
<br />option for a particular spill situation upon finding that the uncertainties associated with that option pose special concerns at
<br />that site. That is, the Regional Administrator would not permit encapsulation if he/she determined that if the encapsulation
<br />failed the failure would create an imminent hazard at the site.
<br />Low-contact, outdoor surfaces (both impervious and nonimpervious) shall be cleaned to 100 pg/100 cm 2.
<br />Soil contaminated by the spill will be cleaned to 25 ppm PCBs by weight.
<br />(4) Requirements for decontaminating spills in nonrestricted access areas. Spills which occur in nonrestricted access locations, as
<br />defined under § 761.123, shall be decontaminated in accordance with paragraphs (c)(4) (i) through (v) of this section. Conformance
<br />to the cleanup standards at paragraphs (c)(4) (i) through (v) of this section shall be verified by postcleanup sampling as specified
<br />under § 761.130.
<br />Furnishings, toys, and other easily replaceable household items shall be disposed of in accordance with the provisions of
<br />subpart D of this part and replaced by the responsible party.
<br />Indoor solid surfaces and high-contact outdoor solid surfaces, defined as high contact residential/commercial surfaces under
<br />§ 761.123, shall be cleaned to 10 pg/100 cm2 (as measured by standard wipe tests).
<br />Indoor vault areas and low-contact, outdoor, impervious solid surfaces shall be decontaminated to 10 pg/100 cm 2.
<br />At the option of the responsible party, low-contact, outdoor, nonimpervious solid surfaces shall be either cleaned to 10 pg/100
<br />cm 2 or cleaned to 100 pg/100 cm2 and encapsulated. The Regional Administrator, however, retains the authority to disallow
<br />the encapsulation option for a particular spill situation upon finding that the uncertainties associated with that option pose
<br />special concerns at that site. That is, the Regional Administrator would not permit encapsulation if he/she determined that if
<br />the encapsulation failed the failure would create an imminent hazard at the site.
<br />Soil contaminated by the spill will be decontaminated to 10 ppm PCBs by weight provided that soil is excavated to a minimum
<br />depth of 10 inches. The excavated soil will be replaced with clean soil, i.e., containing less than 1 ppm PCBs, and the spill site
<br />will be restored (e.g., replacement of turf).
<br />(5) Records. The responsible party shall document the cleanup with records of decontamination. The records must be maintained for a
<br />period of 5 years. The records and certification shall consist of the following:
<br />Identification of the source of the spill, e.g., type of equipment.
<br />Estimated or actual date and time of the spill occurrence.
<br />The date and time cleanup was completed or terminated (if cleanup was delayed by emergency or adverse weather: the nature
<br />and duration of the delay).
<br />A brief description of the spill location and the nature of the materials contaminated. This information should include whether
<br />the spill occurred in an outdoor electrical substation, other restricted access location, or in a nonrestricted access area.
<br />Precleanup sampling data used to establish the spill boundaries if required because of insufficient visible traces and a brief
<br />description of the sampling methodology used to establish the spill boundaries.
<br />A brief description of the solid surfaces cleaned.
<br />Approximate depth of soil excavation and the amount of soil removed.
<br />Postcleanup verification sampling data and, if not otherwise apparent from the documentation, a brief description of the
<br />sampling methodology and analytical technique used.
<br />While not required for compliance with this policy, information on the estimated cost of cleanup (by man-hours, dollars, or
<br />both) would be useful if maintained in the records.
