An overview of the superfund addressing issues regarding hazardous wastes

Ensuring compliance with the Act, as with most other federal environmental laws, is the responsibility of the U. Each of the sites inspected relied primarily on the results of real-time monitoring for organic vapor and dusts to characterize employee exposures.

In other words, the Act is proactively focused on source reduction of pollution, rather than reactively focusing upon how to deal with pollution once it has entered the environment. The SAHP did incorporate, by reference, a series of corporate SOPs covering certain of these topics, such as hot work and confined space entry work, although these SOPs had not been revised as necessary to address site-specific factors, despite a requirement in the corporate SOPs to do so.

Also at this site, inspection team members observed that overspray from the equipment decontamination area presented a potential exposure hazard to personnel in an adjacent Level D PPE area; thus, although the procedures used to decontaminate equipment at this site may have been effective, the methods employed created another potential exposure hazard that was readily apparent even on direct visual observation.

If a threatened or endangered species will be adversely affected, the EPA can also issue an emergency suspension of certain pesticides. In addition, management at Site E paid inadequate attention to the monitoring program, as evidenced by the late submission of samples for laboratory analysis.

In estimating the volume, use the dimensions of the source. Category 3 chemicals have sufficient screening data to An overview of the superfund addressing issues regarding hazardous wastes endocrine activity, but data to characterize actual effects are inadequate and will need testing.

Operation of the filter press cleaning operation, which involves spraying filter presses with a stream of water, revealed that the employee engaged in the operation was exposed to splashes of contaminated liquids on the back of his head and neck because the protective clothing he was using was inadequate.

The SERCs and LEPCs are responsible for providing the community with information on chemical hazards that may affect the public and the dissemination of procedures to be followed in the event there is an emergency hazardous situation.

Hazardous Waste Management

Otherwise, assign a minimum factor value of 10 to the pathway. SARA also mandate that the Hazard Ranking System HRS be revised to make sure of the adequacy of the assessment of the relative degree of risk to human health and the environment posed by uncontrolled hazardous waste sites that may be placed on the NPL.

To be maximally useful, both documents should be available in the control zone where employees can refer to them as needed. The SAHP developed for Site E did not address all anticipated emergencies, including procedures to be followed in the event of natural gas line rupture or fires.

This seems to vary considerably by the type of pesticide, but it suffices to say that the air pathways are important. This area is also known as the footprint of the source. The state acts must have provisions in place which meet, if not exceed, the federal OSHA requirements.

Interviews with safety and health personnel at these sites indicated that no single site safety and health supervisor who had overall responsibility for the enforcement of safety and health requirements for all personnel on site had been designated.

Overview: Key Federal Environmental Laws

The level of PPE assigned to employees was based primarily on the location of the operation rather than on the concentration of the contaminants to which employees were exposed.

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. This Tier A information i. Another example concerns the maintenance operation conducted about once per week at the site that requires employees to enter the secondary kiln to chip away slag that accumulates on the inner walls.

At Site A, written hazard analyses were not available for several operations, including: Manufacturers and importers of chemical substances first submitted information about chemical substances already on the market during an initial inventory.

RCRA also contains provisions for the management of nonhazardous solid wastes. Procedures to monitor for and reduce heat stress need to be effective. 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.

In contrast, hazard analyses were available for all tasks and operations at Site D.

Toxic trail: the weak points in the Superfund waste system

Thus, no Tier A evaluation can be performed. Other deficiencies in the emergency plan at Site A included the following: Tracking waste once it leaves a site is almost impossible When the Superfund law was enacted in the s, Congress was concerned that it would create more toxic waste sites by shipping out Superfund waste.

In this case, the procedure for determining the WC factor value is a bit more complex and the maximum value is 1, Each year, companies decide whether the waste leaving their site will be considered hazardous or not based on sample tests.

Tier D Area information is used if, and only if Tier C information is not available. The Act makes it unlawful for any person to discharge any pollutant from a source point into navigable waters of the United States unless they have obtained a special permit allowing such activity from the EPA. To arrive at the HWQ for the migration pathway, sum the applicable source HWQs for that pathway, rounding to the nearest integer.

This is discussed in further detail in Section 18 on the soil exposure pathway. To re-emphasize, Tier B information includes waste volume that can be converted to mass units, Tier C information is restricted to the volume of the source not the volume of the wastes placed in the source.

Thus, the emergency alerting procedures did not conform to the requirements of But the agency chooses not to quantify or monitor them. In addition, it was observed that cotton coveralls worn under Tyvek protective clothing showed visible signs of contamination after employees had finished using a high-pressure water wash to decontaminate large excavated items; this suggests that a more impervious type of protective clothing such as double-seamed Tyvek should be used during this operation.

Once the source hazardous waste quantity value has been evaluated for each source or area of observed contamination including as applicable, the unallocated sourcethe hazardous waste quantity value is calculated as the rounded sum of the source or area of observed contamination values and assigned a factor value using Table Key Federal Environmental Laws Overview:Toxic trail: the weak points in the Superfund waste system If the waste is deemed hazardous, it’s more closely regulated.

If it’s nonhazardous, it can be disposed of more inexpensively and. 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.
