National Plant Standard

When the objective of water treatment is to provide drinking water, then we need to select technologies that are not only the best available, but those that will meet local and national quality standards. The primary goals of a water treatment plant... 

A National Emission Standard for Hazardous Air Pollutants (NESHAP) for new and existing hydrochloric acid process steel pickling lines and HC1 regeneration plants pursuant to Section 112 of the Clean Air Act as amended in November 1990 has been proposed (62 FR 49051, September 18,1997). The purpose of this rulemaking is to reduce emissions of HC1 by about 8360 megagrams per year.

EPA Vinyl Chloride Standard. On October 21, 1976, the Environmental Protection Agency (EPA) promulgated the National Emission Standard for Vinyl Chloride (35) under the provisions of Section 112 of the Clean Air Act (42 U.S.C., Section 7412) which provides for national emission standards for hazardous air pollutants (NESHAP) that present a threat of increased mortality or serious irreversible illness. This standard provides emission standards applicable to ethylene dichloride, vinyl chloride, and PVC plants. In the case of PVC plants, this requires the following ...

There should be complete agreement on the requirements against which the piant is to be audited. For example Will the plant be audited against corporate standards/requirements, piant standards/requirements, or national/internationai standards The standards or requirements used to conduct the audit should be written and published so that everyone is in agreement on expectations. 

The Clean Water Act also establishes a framework whereby states and Indian tribes survey their waters, determine an appropriate use (such as recreation or water supply), then set specific water quality criteria for various pollutants to protect those uses. These criteria, together with the national industry standards, are the basis for permits that limit the amount of pollution that can be discharged to a water body. Under the National Pollutant Discharge Elimination System, sewage treatment plants and industries that discharge wastewater are required to obtain permits and to meet the specified limits in those permits. 

Yom local OHS legislation may include specific controls to be applied to certain types of plant, tools or equipment. These controls may specifically include the need for a person operating plant to be competent. There may be national certification standards for competency to operate, for example, cranes and hoists, and pressure vessels. Scaffolding and rigging may also be covered. Certain types of plant may need to be registered with a goverrunent authority.

Permitting is based on assessment of potential degradation of the environment, and thus both the level of emissions from the plant and the present level of contamination in the local environment are considered. There are National Ambient Air Quality Standards (NAAQS) for a few materials and National Emissions Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS) for these and others. Major sources (defined as those plants that emit more than some annual threshold quantity such as 25 tons of hazardous air pollutants) must meet the most stringent emissions criteria and require more permits. Similar standards are applied for water quality and for discharges into the water. Many of these regulations are based on the Clean Air Act and Clean Water Act, among others.
