    The Environmental Protection Agency proposed changes to its analysis and sampling test procedures in its wastewater regulations. Municipal wastewater treatment plants and companies required to monitor their wastewater discharges under the Clean Water Act permits will have more flexibility in how they test for pollutants. The Sept. 23 proposal affects provisions in 40 CFR 126, 260, 423, 430, and 435. The proposal would expand the list of new approved methods for testing pollutants under the National Pollutant Discharge Elimination System program. The pollutants include, among others, ammonia, arsenic, phosphorus, potassium, selenium, and volatile residues. The proposal also would add analytical methods developed by EPA and voluntary standards development organizations, and clarify the process for EPA approval for use of alternate procedures for nationwide and regional use.
