• The Environmental Protection Agency (EPA) has finally promulgated its final rules for industries to pretreat toxic wastes before they are discharged into municipal wastewater treatment plants, and the amended rules appear to have quieted the complaints of a number of groups including the Chemical Manufacturers Association. Goals of the pretreatment program are unchanged: 1. to prevent industrial wastes from interfering with the treatment operation, and 2. to prevent sewage sludge from being contaminated. However, some EPA changes will make things easier for chemical companies, including: 1. EPA is allowing treatment plants to revise discharge limits on a conditional basis prior to approval of the entire pretreatment program. 2. Removal allowance authorizations can be requested every year. 3. Only pollutants that cause or contribute significantly to a violation of the plant's discharge permit are classed as interfering with operation of the treatment plant. Despite changes, some observers still feel the pretreatment program is totally inoperable.
