Regulations/standards source

According to official regulations, solid standard sources are generally submitted to classical tests of non-contamination by wiping or by immersion, as required. However, in view of the meteorological quality required, some standards being brittle and of low level activity, these tests are not performed in order to avoid any alteration of the standards or of their accuracies. On the other hand, the sealed sources are submitted to strict tests. 

ABSTRACT The objective of this study was to use the CALPUFF modeling system to predict the concentrations of CO, NO, and COj released, due to the traffic, from the Sultan Qaboos University (SQU) facility at its location in Muscat, Sultanate of Oman. These pollutants were selected as the indicator since they were the most dominant products of vehicle emissions. The study focused on investigating the dispersion of CO, NO and COj by considering the SQU as an area source. The results from the CALPUFF model clearly demonstrated that the levels of the three targeted pollutants, emitted from the vehicles, were found to significantly exceed the allowable limits defined by regulated standards. 

Current compliance requirements for hoists are different from state to state and country to country. Compliance requirements can come from several sources including legislative, health and safety acts, regulations, standards and codes. The recent trend in these documents is to move away from the prescriptive to more risk based approach. This is where a standard like... 

Title V permits must assure compliance with all federal applicable requirements. Applicable requirements are essentially all the rules, regulations, standards and permit conditions for the control of air pollution to which a source is subject under the Clean Air Act. Applicable requirements are defined in 40 CFR Part 70 and corresponding state regulations, and include ... 

We see queries and views as a means to express, respectively, specific questions relevant for argument structure creation, review, or modification, and their responses. Potential sources of queries, besides the experience of the safety engineer or the assessor, includes domain knowledge, such as that contained in regulations, standards, guidance documents, artifact documentation, documentation for processes and procedures, etc. To illustrate, we give some scenarios ... 

States are required to teil the EPA how they plan to achieve compliance with the federal air quality standards (NAAQS) through a State Implementation Plan (SIP). The plans outline the strategy a state wiii use in regulating polluting sources. Each plan establishes enforceable schedules for installing needed pollution control equipment and instituting other control measures. These plans must be approved by the EPA (CAWG, 1989 Vernon, 1989).

Sources Subject to Prevention of Significant Deterioration (PSD) Sources subject to PSD regulations (40 CFR, Sec. 52.21, Aug. 7, 1980) are major stationary sources and major modifications located in attainment areas and unclassified areas. A major stationaiy source was defined as any source hsted in Table 25-4 with the potential to emit 100 tons per year or more of any pollutant regulated under the Clean Air Act (CAA) or any other source with the potential to emit 250 tons per year or more of any CAA pollutant. The potential to emit is defined as the maximum capacity to emit the pollutant under apphcable emission standards and permit conditions (after apphcation of any air pollution control equipment) excluding secondaiy emissions. A major modification is defined as any physical or operational change of a major stationaiy source producing a significant net emissions increase of any CAA pollutant (see Table 25-5). 

The pollutants, source categories, and affected facilities for which the United States has established New Source Performance Standards are listed in Table 25-1. Certain categories listed in Table 25-1 are subject to U.S. Prevention of Significant Deterioration (of air quality) (PSD) review if their emission potential of a regulated pollutant exceeds 100 tons per year. In... 

When owners wish to build a new source which will add a specific amount of a specific pollutant to an area that is innonattainment with respect to that pollutant, they must, under U.S. federal regulations, document a reduction of at least that amount of the pollutant from another source in the area. They can effect this reduction, or "offset," as it is called, in another plant they own in the area or can shut down that plant. However, if they do not own another such plant or do not wish to shut down or effect such reduction in a plant they own, they can seek the required reduction or offset from another owner. Thus, such offsets are marketable credits that can be bought, sold, traded, or stockpiled ("banked") as long as the state or local regulatory agency legitimizes, records, and certificates these transactions. The new source will still have to meet NSPS, BACT or MACT, and/or LAER standards, whichever are applicable. 

Select one source category and affected facility from Table 25-1 and determine the detailed performance standards for the pollutants regulated. 

Because mobile sources of air pollution are capable of moving from one local jurisdiction to another, they are usually regulated by the national government. In the United States, state or local agencies can have more restrictive standards, if they choose. Through 1990, only the state of California had established standards more restrictive than the U.S. federal standards, and these only for gasoline-powered automobiles. 

To determine compliance with regulations. If authorization is obtained to construct an incinerator and the permit states that the maximum allowable particulate emission is 230 mg per standard cubic meter corrected to 12% CO2, a source test must be made to determine compliance with the permit.
