SECTION C. APPLICABILITY
This permit is applicable to the following types of discharges defined below:
1. Non-contact cooling water and open recirculation cooling water systems used in industrial processes for the
sole purpose of cooling machinery and other equipment. Non-contact cooling water is defined as water used
for cooling which does not come into direct contact with any raw material, intermediate product, waste
product or finished product. Contact cooling water is defined as cooling water that comes into contact with
raw material,intermediate product,finished product,byproduct or waste product.Open recirculating cooling
water systems,continuously terms the cooling water which passes through the heat transfer equipment.Open
recirculating cooling water system discharges to a Water Supply water body may require an individual
NPDES permit. Contact cooling water discharges require an individual NPDES permit.
2. Condensate wastewater from atmospheric cooling systems,
3. Blowdown wastewaters. Blowdown is defined as the minimum discharge of recirculating water for the
purpose of discharging materials contained in the water, the further buildup of which would cause
concentration in amounts exceeding limits established by best engineering practice.
4. Exempt stormwater, which is defined as discharges of stormwater which do not require permits under the
state or Federal NPDES programs. Exempt stonnwater includes stormwater which accumulates in outdoor
basins or ponds designed for cooling water or other waters covered by this permit,
5. Water associated with hydroelectric power facilities,including cooling waters,waters from sumps and drains,
dam seepage and exempt stormwater.
6. Other similar wastewaters which may qualify for coverage under this General Permit. �-
