The Federal Water Pollution Act of 1972, amended in 1977 and 1987, gives the U.S. Environmental Protection Agency (US EPA) the authority to establish and enforce pretreatment standards of the indirect discharge of industrial wastewaters.
The intent of these regulations is to prohibit the discharges of wastes that are incompatible with the Water Pollution Control Facility (WPCF) processes. To be specific, the pretreatment program has four objectives (40 CFR Part 403.2):
Kendallville is one of 45 municipalities in Indiana that have approved pretreatment programs. Approved pretreatment programs issue wastewater discharge permits, authorizes monitoring, compliance and enforcement activities, establishes administrative review procedures, requires industrial user reporting and provides for the setting of fees for the equitable distribution of cost resulting from the program.
Kendallville has two "Biosolids" permits approved through the IDEM. One is an Non-Site Specific land application permit and the other is a Marketing and Distribution (Give-Away).
Kendallville's "Biosolids" have been designated as Class A, thus allowing Kendallville WPCF to make solids available to the public.
