Industrial General Permit Fact Sheet

would supersede this General Permit. To date, two Regional Water Board have
issued such permits:

i. The Lahontan Regional Water Board has adopted an NPDES permit and
general Waste Discharge Requirements to regulate discharges from marinas
and maintenance dredging (Regional Water Board Order R6T-2005-0015 -
NPDES Permit No. CAG616003) in the Lake Tahoe Hydrologic Unit.

ii. The Santa Ana Regional Water Board adopted the Sector Specific General
Permit for Stormwater Runoff Associated with Industrial Activities from Scrap
Metal Recycling Facilities within the Santa Ana Region, Order R8-2012-0012,
NPDES Permit No. CAG 618001 (Scrap Metal Recycling Permit). The Scrap
Metal Recycling Permit is applicable to facilities within the Santa Ana Region
that are listed under Standard Industrial Classification (SIC) Code 5093 and
engaged in the following types of activities: (1) automotive wrecking for scrap-
wholesale (this category does not include facilities engaged in automobile
dismantling for the primary purpose of selling second hard parts); (2) iron and
steel scrap - wholesale; (3) junk and scrap metal - wholesale; (4) metal waste
and scrap - wholesale; and (5) non-ferrous metals scrap - wholesale. Other
types of facilities listed under SIC Code 5093 and engaged in waste recycling
are not required to get coverage under the Scrap Metal Recycling Permit. A
list of covered facilities as of February 8, 2011 was included in Attachment A
of the Scrap Metal Recycling Permit.

c. Discharges that the Regional Water Boards determine to be ineligible for
coverage under this General Permit. In such cases, a Regional Water Board will
require the discharges be covered by another individual or general NPDES
permit. The applicability of this General Permit to such discharges is terminated
when the discharge is subject to another individual or general NPDES permit.

d. Discharges that do not enter waters of the United States. These include:

i. Discharges to municipal separate sanitary sewer systems;

ii. Discharges to evaporation ponds, discharges to percolation ponds, and/or
any other methods used to retain and prevent industrial storm water
discharges from entering waters of the United States;

iii. Discharges to combined sewer systems. In California, the only major
combined sewer systems are located in San Francisco and downtown
Sacramento. Dischargers who believe they discharge into a combined sewer
system should contact the local Regional Water Board to verify discharge
location; and,

iv. Dischargers Claiming the “No Discharge” Option in the Notice of Non-
Applicability (NONA) (Fact Sheet Section II.S).

e. Discharges from mining operations or oil and gas facilities composed entirely of
flows that are from conveyances or systems of conveyances used for collecting
and conveying precipitation runoff and do not come into contact with any
overburden, raw materials, intermediate products, finished products, by-products,
or waste products located at the facility. (33 U.S.C. § 1342(l)(2).)

f. Discharges from facilities on Tribal Lands regulated by U.S. EPA.
