Best conventional control technology

Best practicable control technology currently available (BPT) and best conventional control technology (BCT) guidelines for the control of conventional pollutants (biological oxygen demand, total suspended solids, and pH)... 

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),... 

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. 

Note pH (within the range of 6.0 to 9.0) BPT incorporates BAT and BCT BPT, best practicable control technology NS, new source performance standards BOD, biochemical oxygen demand TSS, total suspended solids COD, chemical oxygen demand O G, oil and grease BAT, best available technology economically achievable BCT, best conventional pollutant control technology.

CWA to establish the minimum level of control to be required by a permit. They are the Best Practicable Control Technology (BPT), Best Available Technology Economically Achievable (BAT), Best Conventional Pollutant Control Technology (BCT), Best Available Demonstrated Technology (BDT), and Best Management Practices (BMPs). Industries that do not discharge directly into surface waters but into publicly operated treatment works (POTWs) are subject to pretreatment standards under Section 307(b) of the CWA. 19.3.1.3 Permit Program... 

Best practicable control technology crurently available for conventional, toxic, and nonconventional pollutants ... 

On August 23, 1978 (43 FR 37570), the EPA proposed a new approach to the control of conventional pollutants by effluent guideline hmitations. The new guidelines were known as best conventional pollutants control technology (BCT). These guidelines replaced the existing BAT limitations, which were determined to be unreasonable for certain categories of pollutants. 

BCT means the best conventional pollutant control technology under U.S. Federal Act Section 304(b)(4).

Best conventional technology (BCT) for control of conventional pollutants and applicable to existing dischargers... 

All pollutants are classified as either conventional, toxic, or nonconventional. Conventional pollutants include BOD5,TSS (total suspended sohds), and pH.There are 129 priority pollutants that appear on the toxics hst in the Federal Register 43(164)4108 (February 1978). Nonconventional poUutants are those that are neither toxic nor conventional, such as nitrogen, oil, and grease. Best conventional pollutant control technology was required for conventional pollutants by July 1,1984. Best available technology economically achievable was also required for toxic and nonconventional pollutants by the same date.
