An overview of the superfund addressing issues regarding hazardous wastes

EPA Memorandum, February Follow-up to the February memorandum pertaining to the signing of hazardous waste manifests. The exposure monitoring program at Site B was the most complex of the programs at all sites inspected.

The Pollution Prevention Act The Pollution Prevention Actpassed inincludes provisions aimed at reducing the amount of pollution in the environment by making changes in production, operation, and use of raw materials by both private industry and the government.

Furthermore, employees wearing respiratory protection equipment were observed to be working without the benefit of direct observation by a designated buddy.

For example, the SOP did not identify the specific locations of the confined spaces at the site. However, when shown the deficiencies identified by OSHA, personnel form the oversight agency emphasized that they expected the site safety and health supervisor to exercise authority over any person present on site, including their own personnel, if necessary.

For example, although the contractor was free to upgrade the level of PPE when site conditions so warranted, downgrading the level of PPE required the submission of a written justification to the Contracting Officer and the receipt of written approval before a downgrade could be implemented.

Since, in this case, the hazardous wastestream quantity is adequately determined, the source hazardous waste quantity value would be determined based on the maximum of the Tier A and Tier B values evaluated using Table For example, the SAHP developed for Site B did not include written safety and health procedures and protective measures to be used for the emergency shutdown of the incinerator.

In addition, alternate evacuation routes should have been established for employees working in the exclusion zone; only one evacuation route was indicated in the SAHP. Paragraph h of the standard also requires that the exposures of employees be monitored to ensure adequate characterization of their exposures; the results of all exposure monitoring should feed back into the hazard analysis process to ensure continuing improvement in site planning and procedures.

Allowing a situation of this type to continue clearly undermines any effort to convey to employees the need to take appropriate protective measures to guard against exposure to hazardous conditions.

The information in each of the four tiers, however, are measured in different units. For example, the initial version of the Act either did not address, or did not sufficiently address, issues such as acid rain, ozone depletionand air toxins.

Tier B, Hazardous Wastestream Quantity, is the second tier Tier B of information for a source to be evaluated by the scorer. As a consequence, changes in safety and health procedures are not being incorporated into the SAHP.

The evaluation of the HWQ factor for the migration pathways begins with the assignment of hazardous substances and hazardous wastestreams to the sources at the site based on the available information.

In addition, the WC factor category value is subject to a maximum ofexcept when the bioaccumulation potential factor value BPFV is considered in two of the surface water pathway threats. Therefore, the health personnel on these sites need to reevaluate their criteria for determining where the buddy system is necessary, and to formalize the use of the buddy system in those areas so that employees have a clear understanding of the importance of adhering to the buddy requirement.

They are summarized as follows: Further, the SAHP for this site failed to address the emergency response plan for chemicals brought onto the site such as fuel or wastewater treatment plant chemicals, although the emergency response plan did address spills of the identified landfill contaminants.

If so, determine if the data accounts for all hazardous substances in the source. Hazardous Wastestream Quantity Tier B information, which is used when Tier A data are not adequately determined, represents the quantity of the wastestreams that went into the source.

SARA required that Superfund actions consider the standards and requirements found in other state and federal environmental laws and regulations and provided revised enforcement authorities and new settlement tools.

Otherwise, assign a minimum factor value of 10 to the pathway. Start at Tier A and determine if there is enough good quality data to evaluate it. The state acts must have provisions in place which meet, if not exceed, the federal OSHA requirements. It is used only if the source was not assigned a Tier C measure and if Tiers A and B were not adequately determined.

This deficiency was particularly important at this site because a number of employees reported experiencing signs of respirator cartridge breakthrough or facepiece leakage, despite personal sampling results indicating that exposures to benzene and vinyl chloride were low. In addition, the written Spill Response Plan contained procedures for conducting monthly meetings, drills, and periodic spill containment inspections; none of these procedures were being implemented at the site.

These deficiencies are discussed in more detail below. To this end, direct reading instrumentation can be used on an on-going basis to determine the appropriate level of respiratory protection after employee exposure has been adequately characterized through the use of personal samples.

FIFRA requires that farmers, utility companies, and other users of pesticides register when they purchase pesticides.This publication goes beyond other publications by emphasizing the scientific, policy, and legal issues that make hazardous waste management a difficult This text is a cursory overview of hazardous wastes and their management from both a technical and a regulatory perspective.

and Superfund. The RCRA law covers both hazardous and. Hazardous Wastes and the Superfund Act Chapter 19 (part) – Manahan, 7 th ed. Definition Hazardous wastes = substances that have been discarded or Q. How long ago was the first hazardous waste generated? = substances that may interact with other substances to be status and other details regarding each Superfund site as of.

InCongress passed CERCLA for the purpose of addressing how uncontrolled or abandoned hazardous waste sites, accidents, spills, and other emergency releases of pollutants or contaminants should be handled. The Act creates a federal "Superfund" to clean up, contain, or remove pollutants and hazardous materials in these situations.

In the third case, concentration data quality considerations (e.g., representativeness, accuracy, and precision) become very important, as does the restriction regarding the constituents of RCRA hazardous wastes.
