4. This question has similarities to a sample problem on hydrofluoric acid in an earlier narrative and a sample problem on glass production earlier in the course. Quality Rice proposes to construct a NEW facility along the Texas Guif Coast will process rice into parboiled rice. This facility will discharge pollutants via its wastewater. Answer the following questions based on the technology standards for the applicable industry subcategory, which is within the Grain Mills point source categow. Note that there are several subcategories within this category, so watch that you are using the correct one. Also, if the answer does not clearly match the questions asked, you likely are not in the correct iocation. Searching by the contaminant is NOT the way to approach this question. (27% totai, 4% each, except 3% on g.) These standards are found in the federal regulations in Title 40 of the Code of Federal Regulations (CFR). Note that existing facilities should be using BAT or BCT technology by now, and new facilities need to use the New Source Performance Standards (NSPS) values. For some specific industries, BCT is defined as the same as BPT, the earlier standard, and sometimes it is different. Hints: The technology based, industry specific wastewater standards for all industries are located close together in two volumes of the CFR. Once you find where these standards are located, look for the industry group that applies. If you do not find CLEAR answers, you probably are looking in the wrong place. The sample problem in Unit 3 should provide some guidance on where to look and how to address this type of problem. Note that for wastewater, standards often are stated in grams, kilograms, or pounds of pollutant per unit of production or amount processed (kkg of product, 1000 square feet of product, or 1000 pounds of product} rather than a concentration. If only a concentration is used, there might be an incentive to meet the standard by diluting with more water. Dilution is not consistent with the intent to minimize the amount of pollutants entering water bodies. How is the term "rice" dened in this regulation? . For the New Source Performance Standards [NSPS], what is the maximum amount of TSS that is allowed in the wastewater, as a maximum for any one (13 day? kg per 1,000 kg of rice For the NSPS, what is the maximum amount of TSS that is allowed in the wastewater, as an average of daily values for 30 consecutive days? kg per 1,000 kg of rice Note that the regulations consider that the level of pollutants will tianir somewhat from day to day. The max value for 1 day is more than the average allowed over 30 days. . State where this information responding to a. above is found in the regulations, being as specic as possible.
