6, or TR.1CA CITYF ■T 3 0 C AA c CY Utilities Division 3900 Holly Drive Telephone: (209)836-1650 "�oRPORP`�° Tracy, CA 95376 Fax: (209)836-0932 The attached schematic shows the sludge handling process. Operation Our permit requires that we track metals loadings, both annual and cumulative, to our fields. We can demonstrate from this data that we are meeting the Class B application requirements. Ongoing monitoring may show that we will consistently meet Class A requirements. I am enclosing annual and cumulative metals loadings for your review. In calendar year 1994, we applied sludge to fields that were used to grow beans and alfalfa. Since our program began in 1990, we have also applied to fields growing almonds and sugar beets. The almonds and beans are above ground food crops that are harvested prior to 14 months after application. We have confirmed, with you, however that almonds and beans, crops with hulls, were not intended to fall within this restriction. We will continue to consider it acceptable to apply to these crops, at agronomic rates, in the future. Certification Statement I certify, under penalty of law, that Class B pathogen requirements in paragraph 503.32(b) and the vector attraction reduction requirement in paragraph 503.33(b)(8) have been met. This determination has been made under my direction and supervision in accordance with the system designed to ensure that qualified personnel properly gather and evaluate the information used to determine that the pathogen and vector attraction reduction requirements have been met. I am aware that there are significant penalties for false certification including fine and imprisonment." Sincerely, C� Darrell D.
