Primary RCRA regulations call for a DRE of at least 99.99% of all POHCs. The regulations also require 99% removal of HCl from the incinerator flue gas or a maximum of 41b/h (1.8kg/h). Federal regulations require a maximum particulate emission of 0.08 gr/dscf corrected to 7% oxygen in the flue gas. In addition, many states require BACT (best available control technology). Metals emissions are dealt with in the next problem. 

CO and Particulates. For CO and PM 10, Title I required oxygenated gasoline in the winter for areas where the ambient CO level exceeded 9.4 ppm. For areas where CO exceeded 12.7 ppm, enhanced I/M and predictions of vehicle miles travelled (VMT) were required. As in severe ozone areas, serious CO areas had to impose TCMs. Areas where PM 10 levels exceeded EPA limits had to reach compliance by December 1994, with possible extensions to 2001. Moderate PM 10 areas had to adopt RACT, and serious areas had to adopt BACT (best available control technology). 

In attainment areas, new large faciUties must be designed to incorporate the best available control technology (BACT). Generally, BACT is more stringent than RACT and equal to or less stringent than LAER. In addition, there are also rules that specify how much deterioration in baseline air quaUty a new facihty can cause. In no situation can the faciUty cause a new violation in the NAAQS. 

The effluent standards require two levels of treatment best practicable control technology (BPCT) and best available control technology (BACT). New standards covering additional industries are stiU being issued. Of special concern to the chemical industry are the following Hsted categories ... 

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. 

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. 

We should note that in a general sense, the objective of pollution abatement is compliance. Whether we apply conventional controls or P2, the intent is to develop corrective actions that largely focus on the lowest achievable emission rate (LAER) technologies, and only sometimes on best available control technologies (BACT),... 

Best Available Control Technology (BACT) the control level (or control measures) required for sources subject to the Prevention of Significant Deterioration program (see 40CFR 52.21(b)). 

Best Available Control Measures (BACM) see BACT. 

Facilities in NAAQS attainment areas must follow PSD requirements by demonstrating that the construction/modification project will not cause a violation of air quality limits and will implement the best available control technology (BACT). 

The facility is designed with the use of the best available control technology (BACT), e g., PLC/DCS, process management systems that are commensurate to the level of risk the facility represents.

Best Available Control Technology (BACT) - The most currently commercial optimum hardware and operating methodology applied to a process. 

Cracking (FCC) units have been established through consent decree between the EPA and the rehnery or by the application of new source review (NSR) provisions of the Clean Air Act when making rehnery modihcations that result in a signihcant emission increase. NSR standards require facilities to apply best available control technology (BACT) in ozone attainment areas and the lowest achievable emissions rate (LAER) in ozone nonattainment areas. In addition, in mid-2009, the U.S. EPA revised the Standards of Performance for Petroleum Rehneries (40 CFR 60 Subpart Ja) to include NO, standards for process heaters and FCCUs.
