New Source Performance Standards NSPS

Emission Standards. In order to have a nationwide basis for air pollution emission controls and to set a minimum emission limit, the EPA developed New Source Performance Standards (NSPS). The NSPS set specific poUutant emission limits or describe the best available control technology (BACT) that should be appUed at that source. The EPA has issued NSPS, which apply to new constmction as weU as to large modifications, for many different sources. Sources in the chemical industry include the foUowing. 

In 1971, EPA estabhshed New Source Performance Standards (NSPS), which required coal-fired utihty boilers built after August 17, 1971 to emit no...

New Source Performance Standards (NSPS) were promulgated under Sections 111(b) and 129 of the CAA Amendments of 1990. The NSPS apphes to new municipal sohd-waste combustors (MWCs) with... 

EPA must issue New Source Performance Standards (NSPS) for any solid waste incineration unit not covered by another deadline lor issuance of such standards. 

Some variants of best practicable means are spelled out in the U.S. Clean Air Act of 1977. One is the requirement that best available control technology (BACT) for a specific pollutant be employed on new "major sources" that are to be located in an area that has attained the National Ambient Air Quality Standard (NAAQS) for that pollutant. BACT is also required for pollutants for which there is no NAAQS [e.g., total reduced sulfur (TRS), for which emission limits are specified by a Federal New Source Performance Standard (NSPS)]. BACT must be at least as stringent as NSPS but is determined on a case-by-case basis. 

New Source Performance Standards (NSPS) - Uniform national EPA air emission and water effluent standards which limit the amount of pollution allowed from new sources or from modified existing sources. 

The environmental impact of SOj emissions has gained much attention over the past ten years. The United States Environmental Protection Agency (EPA) New Source Performance Standards (NSPS) went into effect in 1989. The ruling covers new, modified, and reconstructed FCC units since January 1994. It should be noted that the Southern California Air Quality Management District (SCAQMD) board has established a limit of 60 kilograms of SO per 1,000 barrels of feed for the existing FCC units. 

The gaseous emissions from the FCC unit are CO, NOj, particulates, and SOj. All are either locally or nationally regulated. Table 10-7 shows the current allowable limits of the EPA New Source Performance Standards (NSPS) for the emissions of these airborne pollutants. NSPS levels can be triggered by one of the following conditions ...

Table 8.20 presents the new source performance standards (NSPS) of the steel basis material subcategory. Any new source must achieve the NSPS. 

While medical waste is not subject to federal RCRA regulation, air emissions from new and existing hospital, infectious, and medical waste incinerators are subject to New Source Performance Standards (NSPS) and emission guidelines under CAA. 

In addition to the PSD/NSR preconstruction obligations, there are process-specific operational standards New Source Performance Standards (NSPS). 40 CFR 60 lists these standards, which serve as minimum requirements in states SIPs. Individual states may impose requirements that are stricter. The following NSPSs are particularly relevant to the pulp and paper industry.

The EPA has established four different control technologies for the petroleum refining industry best practicable control technology (BPT), best available technology economically achievable (BAT), best conventional pollutant control technology (BCT), and new source performance standards (NSPS). Table 13 shows the BPT and NSPS standards that must be met by the various subcategories (40 CFR Part 419). The limitations for BPT actually incorporate those of both BAT and BCT for this industry. 

In order to illustrate the typical performance of this system, the EDV system installed at a U.S. refinery is utilized. At this refinery, an EDV wet scrubbing system was installed to bring a new small RCC in compliance with New Source Performance Standards (NSPS) for particulate and SO2 emissions. 

New source performance standards (NSPS) for particulate matter from FCCUs will require refiners to reduce particulate matter in their stacks to below 80 mg/Nm in most areas of the world. Even more stringent standards may follow in coming years including limits on the amount of less than 2.5 micron material. Options for reducing PM emissions from FCCUs are listed in Table 18.1. 

The present sulfur standards (0.97 percent sulfur in SRC) are being met by conventional SRC processing. New Source Performance Standards (NSPS) recently proposed by the Environmental Protection Agency (EPA) would require a sulfur content of 0.5 to 0.6 percent in SRC for most coals. The proposed NSPS could be met using the conventional SRC process with the application of severe operating conditions (e.g., a reaction temperature of 450°C, a pressure of 2,000 psig or 13.9 MPa and a long reaction time of 30 to 60 minutes). 

It 1s Interesting to note that N0X emissions from the synthetic fuels could be lowered to the same level as the N0X emissions from optimized No. 6 fuel oil combustion. From another perspective, optimized synthetic fuel combustion (LEA, BOOS) resulted 1n considerably less NOv than unoptimized No. 6 fuel oil operation (HEA, no BOOS). In terms of regulatory compliance, the BOOS technique was successful 1n lowering N0X emissions to levels below the New Source Performance Standard (NSPS) for coal...
