Evaluate requirements for <br /> compliance with tlie proposed Disinfectants/Disinfection By-Products Rule (D/UBPR), <br /> including 1) the need for and the ability to implement enl�anced coagulation treatment <br /> to remove disinfection by-product precursor compounds prior to disinfection, and 2) <br /> compliance with probable Stage 1 and Stage 2 Maximum Contaminate Levels (MCLs) <br /> for total trihalometllanes and haloacetic acids. Identify potential changes in <br /> disinfection practices which may be required under the impending Long Term <br /> Enhanced Surface Water Treatment Rule (LTESWTR). <br /> Engineer will provide analytical services to test S samples from the distribution system <br /> for total haloacetic acids in order to assess compliance with the D/DBPR. <br /> 'I'aslc 320 - �valuate riltration <br /> Engineer will review the turbidity removal capabilities of tl�e existing filters, witl� <br /> emphasis on operating characteristics at maximum plant rates. Using available data, <br /> the Engineer will evaluate turbidity changes during backwaslling, filter productivity <br /> (gallons produced per square foot of inedia per filter run), backwashing procedures a�id <br /> systems, and backwash disposal practices. The ability to comply with potential future <br /> reductions in allowable filtered water turbidities will be assessed. <br /> Taslc 400 - �valuate Yotential for Co�upliance with 1'ending Regulations <br /> Engineer will assess Owner's current ability to comply witli conclitions ancl limits for <br /> future regulations that are likely to affect Owner's water treatment facility. These <br /> regulations include: <br /> • Interim Enhanced Surface Water Treatment Rule <br /> • Long Term Enl�anced Surface Water Treatment Rule <br /> • Stage 1 of the Disinfectants/Disinfection Byproducts Rule <br /> • Stage 2 of the Disinfectants/Disinfection Byproducts Rule <br /> • Consumer Confidence Reports Rule <br /> • Source Water Protection <br /> • Filter Backwash Water Rule <br /> A-2 <br /> SLW2J:INIJ <br /> 42RNH I <br />
