Release prevention

U.S. Environmental Protection Agency, Risk Management Programsfor Chemical Accidental Release Prevention Proposed Rule Tide 40, Part 68, Subpart B, of the Code of Eederal Regulations (40 CER 68), Federal Register 54212 (Oct. 20,1993). 

Use of Liners. The use of impermeable liners and membranes, often called release prevention barriers (RPBs) under tanks, may be the most effective leak detection and prevention method. On new tanks, it is relatively easy to install these systems, and large numbers of tanks are being built with this type of system in the 1990s. For existing tanks, however, it would be very costiy if not impractical to install liners. For existing tanks, the combination of other methods as well as an effective inspection program can be more effective as a substitute for a release prevention barrier.

OSHA PSM Standard (29 CFR 1910.119) and EPA Accidental Release Prevention Requirements Risk Management Programs (RMP) Under the Clean Air Act, Section 112(r)(7) (40 CFR 68). 

The EPA Accidental Release Prevention Requirements (40 CFR 68) have significant gaps in coverage of reactive hazards. 

Revise the Accidental Release Prevention Requirements, 40 CFR 68 (RMP), to explicitly cover catastrophic reactive hazards that have the potential to seriously impact the public, including those resulting from self-reactive chemicals and combinations of chemicals and process-specific conditions. Take into account the recommendations of this report to OSHA on reactive hazard coverage. Seek congressional authority if necessary to amend the regulation. 

EPA promulgated the Accidental Release Prevention Requirements (40 CFR 68), which contain the list of regulated chemicals and requirements for facilities possessing more than a threshold quantity of a listed chemical in an individual process. Covered facilities are required to implement a risk management program and submit a risk management plan to EPA. 

Unlike OSHA s use of criteria for covering classes of chemicals, such as the criterion for flammable substances as a class, EPA has used only chemical lists for the RMP regulation. The authority provided by Congress in the CAAA for EPA to develop the Accidental Release Prevention Requirements is explicit on the use of a List of Substances (Section 112[r][3]) to identify the covered chemicals. 

The Senate Report on the 1990 CAAA stated that EHS includes substances specifically listed under EPA s Accidental Release Prevention Requirements (40 CFR 68) and substances listed under Section 302 of the Emergency Planning and Community Right-to-Know Act (EPCRA). The definition also includes substances not necessarily listed that-due to their toxicity, reactivity, flammability, volatility, or corrosivity-may cause death, injury, or property damage as a result of short-term exposure upon release to the air. 

Federal legislation for ASTs is also in the process of being mandated under RCRA. This bill would include requirements for development and implementation of a release prevention plan, a tank system that is capable of containing 110% of the content of the tank and preventing off-site release, and inspection of tank systems by a qualified professional engineer. Provisions will also include evidence of financial responsibility and cleanup of product releases. There is little doubt that legislation for ASTs will be more stringent in the years to come.

In 1991, the Spill Prevention Control and Countermeasure (SPCC) rule proposed a revision to require secondary containment that was impermeable for at least 72 h after a release occurred. The 2003 promulgated EPA spec rule no longer mandates a 72-h containment requirement, instead opting to require means to contain releases until they can be detected and removed. Nonetheless, the need for impermeable containment continues to position steel as a material of choice for shop-fabricated tanks. However, release prevention barriers made from plastic or concrete can also meet US EPA requirements when frequently inspected for releases. 

As noted, serotonin synthesis can be inhibited by p-chlorophenylalanine and p-chloroamphetamine. However, these agents are too toxic for general use. Storage of serotonin can be inhibited by the use of reserpine, but the sympatholytic effects of this drug (see Chapter 11) and the high levels of circulating serotonin that result from release prevent its use in carcinoid. Therefore, receptor blockade is the major therapeutic approach to conditions of serotonin excess.
