Regulated substance

The ha2ard assessment is to iaclude identification of a worst-case scenario and other more likely scenarios for release of a regulated substance, and analy2e the off-site consequences of such releases. The release and consequence assessment is to iaclude the rate, duration, and quantity of the release, the distances for exposure or damage (usiag atmospheric, called "F" stabiUty and a 1.5-m/s wiad, and most-often-occurriag conditions), populations that could be exposed, and environmental damage that could be expected.

Did not compile PSI on hazards of regulated substances, technology of process and equipment in process prior to conducting the PHA. 

Catastrophic release Under OS HA PSM and EPA RMP, it means a major uncontrolled emission, fire, or explosion, involving one or more highly hazardous chemical substances (per OSHA) or regulated substances (per EPA) that presents serious danger to employees in the workplace (per OSHA) or imminent and substantial endangerment to public health and the environment (per EPA). 

Under these provisions, EPA must list ail regulated substances along with their ozone-depleHon potenhal, atmospheric lifetimes and global warming potentials within 60 days of enactment. 

Developed under tlie Clean Air Acts (CAA s) Section 112(r), tlie Risk Management Program (RMP) rule is designed to reduce tlie risk of accidental releases of acutely toxic, flanunable and explosive substances. USEPA finalized its list of regulated substances (138 chemicals) and defined tlireshold quantities for these chemicals.

Subtitle I of RCRA was enacted to control and prevent leaks from underground storage tanks.16 It regulates substances, including petroleum products and hazardous material. Tanks storing hazardous wastes, however, are regulated under Subtitle C, and are not the concern of this chapter. 

Further containing the regulated substance to prevent continued release... 

Unless permanently closed, all systems containing regulated substances must continue to comply with all the normal regulatory requirements. USTs closed for less than three months have no special requirements. USTs closed for between three and twelve months must leave vent lines open and cap all other lines. After 12 months out of service, USTs must be closed permanently. Before closing the UST system, the site must be assessed to ensure that no further release has occurred. 

A five-year history of certain accidental releases of regulated substances from covered processes... 

The washed solvent is collected in drums for disposal. The aqueous stream, after analysis, can be sent directly to the publicly owned treatment works (POTW). Limits have not yet been set for dumping versus waste disposal in drums. If the solvent being used is a regulated substance (such as toluene), drum disposal of the HLO may be the only acceptable way. 

Members to regulate substances (within their own territories) when other countries (and the EEC itself) do not concur with such regulations. 

RMP requires covered processes to have a hazard assessment, a prevention program, and an emergency response program. The hazard assessment must evaluate the accidental release of regulated substances, including the worst case scenario. RMP contains requirements for prevention of accidental releases, which include the same basic elements as the OSHA PSM Standard. Therefore, the limitations described in Section 5.1.2.2 with respect to process safety information and process hazard analysis also apply to RMP. 

GDC applies to all stationary sources (fixed facilities) that handle, produce, process, or store regulated substances or extremely hazardous substances (EHS)47. It obligates facilities to identify and safely manage all hazards, including reactive hazards. Similar to OSHA, EPA can use its GDC enforcement authority to create legally binding requirements or enforce actions for hazards that have not been properly identified or managed. 

Acidity regulator Substance which alters or controls the acidity or alkalinity of a foodstuff... 

There are other complementary or similar elements shared by the two regulations. For example, both regulations share goals (1) to prevent the accidental releases of regulated substances and (2) to minimize the consequences of releases that do occur.

Significant accidental release. Any release of a regulated substance that has caused or has the potential to cause off-site consequences such as death, injury, or adverse effects to human health or the environment, or to cause the public to shelter in place or be evacuated to avoid such consequences. 

Stationary source. USEPA defined source to include the entire facility. Sources are still required to submit one RMP and one registration as part of that RMP for all processes at the source with more than a threshold quantity of a regulated substance. 

The owner or operator of a stationary source that has more than a threshold quantity (TQ) of a regulated substance in a process must... 

In the past twenty years many legal provisions have been created to regulate substance flows (recycling management systems, waste management, electrical and automotive recycling). In many instances these laws exphcitly contain threshold values for certain substances or even ban certain substances. They are thus very effective on the use of these substances in production processes. This is also tme for threshold values of chlorinated compounds in industrial waste, the ban on certain heavy metals in the automotive industry and substance-related requirements for waste water from the textile industry (Annexe 38 of Waste Water Ordinance ). 

This is also accounted for in the planned EU chemicals regulation. Substances that are very persistent and very bioaccumulative can be introduced subject to authorisation, even when there are no scientifically based indications of (eco)toxicological effects.
