Comprehensive Environmental Response Compensation and Liabilities Act

The EPA Contract Laboratory Program (CLP) has responsibility for managing the analysis programs required under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The approved analytical methods are designed to analyze water, soil, and sediment from potentially hazardous waste sites to determine the presence or absence of certain environmentally harmful organic compounds. The methods described here all require the use of GC/MS. 

The analysis programs of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are managed through the EPA s Contract Laboratory Program (CLP).

This chapter addresses the potential for hazardous air emissions from environmental remediation sites. These emissions can occur at hazardous spill locations, at undisturbed remediation sites, and during cleanup of remediation sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or the Superfund Amendments and Reauthorization Act (SARA). Air emissions may pose a potential health risk at these sites. 

CERCLA Comprehensive Environmental Response Compensation and Liability Act. 

Any substance designated under the Clean Water Act and the Comprehensive Environmental Response Compensation and Liability Act (CERCLA) as posing a threat to waterways and the environment when released. 

Under this provision, facilities should notify the LEPC and consequently the SERC of any possible environmental release of specific chemicals. The specific chemicals referred to in SARA Title III are found on the Extremely Hazardous Substance List (40 CER 355) and the Reportable Quantity List (the Comprehensive Environmental Response, Compensation, and Liability Act [CERCLA] Section 103 [a]). 

Provides information about all RCRA regulations and programs including the Resource Conseiwation and Recovery Act (RCRA) Comprehensive Environmental Response Compensation and Liability Act (CERCLA, or Superfund) and Emergency Planning and Community Right-to-Know Act (EPCRA)/Superfund Amendments Reauthorization Act (SARA) Title III. Operates weekdays from 9 00 a.m. to 6 00 p.m., EST, excluding Federal holidays. Sendees are also available in Spanish. 

The toxicological profiles are developed in response to the Superfund Amendments and Reauthorization Act (SARA) of 1986 (Public law 99-499) which amended the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA or Superfund). This public law directed ATSDR to prepared toxicological profiles for hazardous substances most commonly found at facilities on the CERCLA National Priorities List and that pose the most significant potential threat to human health, as determined by ATSDR and the EPA. The availability of the revised priority list of 275 hazardous substances was announced in the Federal Register on November 17, 1997 (62 FR 61332). For prior versions of the list of substances, see Federal RegisternoiiCQS dated April 29, 1996 (61 FR 18744) April 17, 1987 (52 FR 12866) October 20, 1988 (53 FR 41280) October 26, 1989 (54 FR 43619) October 17, 1990 (55 FR 42067) October 17, 1991 (56 FR 52166) October 28, 1992 (57 FR 48801) and February 28, 1994 (59 FR 9486). Section 104(i)(3) of CERCLA, as amended, directs the Administrator of ATSDR to prepare a toxicological profile for each substance on the list. 

These experts collectively have knowledge of methyl parathion s physical and chemical properties, toxicokinetics, key health end points, mechanisms of action, human and animal exposure, and quantification of risk to humans. All reviewers were selected in conformity with the conditions for peer review specified in Section 104(I)(13) of the Comprehensive Environmental Response, Compensation, and Liability Act, as amended.

Reportable Quantity (RQ)—The quantity of a hazardous substance that is considered reportable under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Reportable quantities are (1) 1 pound or greater or (2) for selected substances, an amount established by regulation either under CERCLA or under Section 311 of the Clean Water Act. Quantities are measured over a 24-hour period. 

Ihe implementation of the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) has underscored a number of the weaknesses in our capabilities to measure the chemical characteristics of wastes. We are now being called upon to identify and quantify with unprecedented sensitivity hundreds of chemicals found in many types of materials within waste sites, near discharges of hazardous contaminants, and in the surrounding environments. Extrapolations from a limited number of measurements must indicate the general environmental conditions near waste sites. The measurements have to be made faster and cheaper than ever before, with the precision and bias of each measurement fully documented. Thus, the technical challenges facing the monitoring community are substantial.
