      Part 52 – Approval and Promulgation of implementation Plans Part 52.21 – Prevention of Significant Deterioration (PSD) For any source or a major modification to an existing source, located in an attainment area, where ambient air standards are met, a PSD permit must be granted. Once an area is in attainment, it is possible that the construction of a new source or modification of an existing source could lead to “significant” emissions that bring the area into nonattainment. To avoid this possibility a permit must be obtained by the source prior to the construction or modification. It must be shown whether a significant increase of emissions will occur, through a technical analysis and an air quality modeling, as specified in Part 52.21. One of the requirements of Part 52.21 is that the after construction or modification, the source must monitor mass emissions in tons per year of any pollutant designated under the New Source Review program for at least five years.

      States issue operating permits for both existing and new stationary sources.

      An operating permit may include conditions that require the installation of CEM systems. States may prepare rules for existing sources that are more stringent than those promulgated by the federal agency (Kerstetter 1985). As a result, the stringency of state CEM rules may extend beyond those established for similar sources regulated under NSPS. Monitoring of gases such as HCl or volatile organic compounds may be required, or process cutoffs for excess emissions or real‐time telemetry may be required in the permit. Sources often agree to very stringent CEM requirements to expedite approval of the operating permit.

       Federal Programs Delegated to the States

      Most states have received delegation by the U.S. EPA to regulate the emission sources affected by the following federal rules:

       Part 60 New Source Performance Standards

       Part 64 Compliance Assurance Monitoring.

       Parts 266 and 503 Hazardous and Municipal Waste Incineration

      In implementing these programs, states have developed regulations to assure that affected sources have installed required CEM systems, to see that they are properly certified, and to receive and process excess emission reports and compliance data as required by the applicable rule.

       Part 96 Cross‐State Air Pollution Rule (CSAPR)

      The Cross‐State Air Pollution Rule, of 40 CFR 96, evolved from the Clean Air Interstate Rule (CAIR) and the NOx Budget Program (NBP). After the promulgation of Part 75 and the implementation of the acid rain program, significant progress was made in reducing SO2 and NOx emissions. However, even with 50% reductions in SO2 and NOx emissions, critical load was not being reached. “Critical load” is the level of emissions below which harmful effects to the environment do not occur. Studies indicated that reductions on the order of 75% on top of the previous 50% reductions would be necessary for SO2 and NOx to meet ambient air standards for ozone and particulate matter, as well as
