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
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):
- To prevent the introduction of pollutants to the WPCF that will
interfere with the operation of the WPCF, including interference with
its use or disposal of municipal sludge;
- To prevent the introduction of pollutants to the WPCF that will pass
through the treatment work or otherwise be incompatible with such work;
- To improve opportunities to recycle and reclaim municipal and
industrial wastewaters and sludge; and
- To enable the City of Kendallville to comply with its NPDES permit
conditions, sludge and disposal requirements and any other federal or
state laws to which the WPCF is subject.
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.
