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.

Facilities for separating steam from brine and for power generation were designed by mechanical, chemical, and electrical engineers. Dissolved salts in the brine cause severe scaling and corrosion in wells and pipelines. Chemists and chemical engineers developed new production techniques to overcome these problems, as well as pollution control technology for the operation. 

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

In densely populated areas, a large cogeneration system may be required to comply with emission standards and install pollution control technology. There may also be noise pollution standards and water, air discharge and solid waste disposal permits. 

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. 

BPT, best practicabie control technology currently available BAT, best available technology economically available BCT, best conventional pollutant control technology NSPS, standards of performance for new sources. 

Identification of any necessary pollution control technology programs. 

Influent streams with contaminant concentrations greater than 0.01% generally cannot be treated by air stripping. Even at lower influent concentrations, air strippers may not be able to meet cleanup goals. Typically, some air pollution control technology is required to capture or destroy contaminants in the off-gas stream or the treated effluent.
