PART 129--TOXIC POLLUTANT EFFLUENT STANDARDS--Table of Contents
 
     Subpart A--Toxic Pollutant Effluent Standards and Prohibitions
 
Sec. 129.102  Endrin.

    (a) Specialized definitions. (1) Endrin Manufacturer means a 
manufacturer, excluding any source which is exclusively an endrin 
formulator, who produces, prepares or processes technical endrin or who 
uses endrin as a material in the production, preparation or processing 
of another synthetic organic substance.
    (2) Endrin Formulator means a person who produces, prepares or 
processes a formulated product comprising a mixture of endrin and inert 
materials or other diluents into a product intended for application in 
any use registered under the Federal Insecticide, Fungicide and 
Rodenticide Act, as amended (7 U.S.C. 135 et seq.).
    (3) The ambient water criterion for endrin in navigable waters is 
0.004 [mu] g/l.
    (b) Endrin manufacturer--(1) Applicability. (i) These standards or 
prohibitions apply to:

[[Page 349]]

    (A) All discharges of process wastes; and
    (B) All discharges from the manufacturing areas, loading and 
unloading areas, storage areas and other areas which are subject to 
direct contamination by endrin as a result of the manufacturing process, 
including but not limited to:
    (1) Stormwater and other runoff except as hereinafter provided in 
paragraph (b)(1)(ii) of this section; and
    (2) Water used for routine cleanup or cleanup of spills.
    (ii) These standards do not apply to stormwater runoff or other 
discharges from areas subject to contamination solely by fallout from 
air emissions of endrin; or to stormwater runoff that exceeds that from 
the ten year 24-hour rainfall event.
    (2) Analytical method acceptable-- Environmental Protection Agency 
method specified in 40 CFR part 136.
    (3) Effluent standard--(i) Existing sources. Discharges from an 
endrin manufacturer shall not contain endrin concentrations exceeding an 
average per working day of 1.5 [mu] g/l calculated over any calendar 
month; and shall not exceed a monthly average daily loading of 0.0006 
kg/kkg of endrin produced; and shall not exceed 7.5 [mu] g/l in a 
sample(s) representing any working day.
    (ii) New sources. Discharges from an endrin manufacturer shall not 
contain endrin concentrations exceeding an average per working day of 
0.1 [mu] g/l calculated over any calendar month; and shall not exceed a 
monthly average daily loading of 0.00004 kg/kkg of endrin produced; and 
shall not exceed 0.5 [mu] g/l in a sample(s) representing any working 
day.
    (iii) Mass emission standard during shutdown of production. In 
computing the allowable monthly average daily loading figure required 
under the preceding paragraphs (b)(3) (i) and (ii) of this section, for 
any calendar month for which there is no endrin being manufactured at 
any plant or facility which normally contributes to the discharge which 
is subject to these standards, the applicable production value shall be 
deemed to be the average monthly production level for the most recent 
preceding 360 days of actual operation of the plant or facility.
    (c) Endrin formulator--(1) Applicability. (i) These standards or 
prohibitions apply to:
    (A) All discharges of process wastes; and
    (B) All discharges from the formulating areas, loading and unloading 
areas, storage areas and other areas which are subject to direct 
contamination by endrin as a result of the formulating process, 
including but not limited to: (1) Stormwater and other runoff except as 
hereinafter provided in paragraph (c)(1)(ii) of this section; and (2) 
water used for routine cleanup or cleanup of spills.
    (ii) These standards do not apply to stormwater runoff or other 
discharges from areas subject to contamination solely by fallout from 
air emissions of endrin; or to storm-water runoff that exceeds that from 
the ten year 24-hour rainfall event.
    (2) Analytical method acceptable-- Environmental Protection Agency 
method specified in 40 CFR part 136, except that a 1-liter sample size 
is required to increase the analytical sensitivity.
    (3) Effluent standard--(i) Existing sources. Endrin is prohibited in 
any discharge from any endrin formulator.
    (ii) New sources--Endrin is prohibited in any discharge from any 
endrin formulator.
    (d) The standards set forth in this section shall apply to the total 
combined weight or concentration of endrin, excluding any associated 
element or compound.
