(a) Prohibited wastewater discharges and
certain notifications to water board.
(1) No
person shall discharge, allow to be discharged, or otherwise allow to enter any
of the following proscribed waters or wastes to the water board POTW or MS4,
any sanitary sewer, combined sewer, or to the diversion sewer:
(i) Any pollutant which creates a fire or
explosion hazard, including but not limited to, waste streams with a closed cup
flashpoint of less than 140° F (60° C) as determined by using the test
methods specified in 40 CFR part 262.21.
(ii) Any waters or wastes containing solids,
liquids or gases in sufficient quantity, acting either singly or by interaction
with other properly shredded wastes, which may create damage, cause pass
through or interference, be a hazard to the water board personnel, create a
public nuisance, create a hazard to life, or after treatment cause a violation
of the water board's SPDES discharge permit.
(iii) Any water or wastes which will cause
corrosive structural damage, but in no case those discharged with the following
properties:
(a) having a pH less than
5.0;
(b) having a pH greater than
12.0 for any period exceeding 30 minutes;
(c) having a pH greater than 10.0 for more
than five hours daily or 70 hours monthly;
(d) having by itself or by interaction with a
discharge or discharges from other sources, properties which would cause the pH
of the effluent of the water board POTW or MS4 to be outside the range of
6.0-9.0 for greater than 60 minutes;
(e) having by itself or by interaction with a
discharge or discharges from other sources, any other aggressive property in a
quantity or quality capable of causing damage or hazard to any structure or
equipment;
(iv) any
solid or viscous substance, including but not limited to fats, waxes, greases,
petroleum oil, non-biodegradable cutting oils, or products of mineral oil
origin, of such quantity or size discharged, or by interaction with other
substances, which cause obstruction of flow in the POTW, interference of the
POTW, or pass through;
(v) any
liquid or vapor having a temperature higher than 150° F (65° C) at the
discharge to the water board POTW or MS4. In addition, any liquid or vapor
which causes, either singly or in combination with other wastewater discharges,
the combined influent to the water board POTW to exceed 104° F (40° C)
is also prohibited;
(vi) any
materials containing radioactivity of such half-life, concentration or other
property as may exceed limits established by applicable State or Federal laws,
regulations, guidelines or limitations, or that may cause the water board
POTW's or MS4's effluent or sludge to exceed such laws, regulations, guidelines
or limitations, or to be classified as a hazardous substance under the Federal
Comprehensive Environmental Response, Compensation and Liability Act;
(vii) slug or batch discharges which, in the
opinion of the director, could cause or substantially contribute to an upset of
the POTW treatment process, or result in a violation of the water board's SPDES
discharge permit;
(viii) any waters
or wastes containing substances which, either singly or in combination with
other properly shredded wastes, are not amenable to treatment or reduction by
the wastewater treatment processes employed, or are amenable to treatment only
at excessive cost or amenable to treatment only to such degree that the water
board's POTW effluent cannot meet the requirements of the water board's SPDES
discharge permit;
(ix) any waters
or wastes from a motor vehicle, tank truck or any other mobile conveyance
without prior written authorization by the director, specifying the nature,
volume, manner, time and place of discharge except for such mobile conveyance
discharges from within an SIU facility to sewers carrying water through a
monitoring station;
(x) any
substance which may cause the water board's POTW or MS4 effluent or any other
product of the water board POTW or MS4 such as residues, sludge, furnace
solids, or scum, to be unsuitable for discharge, disposal, reclamation or
reuse. In no case shall a substance discharged to the water board's POTW or MS4
cause the water board POTW or MS4 to be in non-compliance with sludge use or
disposal criteria, air emissions permit, guidelines or regulations affecting
sludge use or disposal pursuant to the Solid Waste Disposal Act (including
title II, more commonly referred to as the Resource Conservation and Recovery
Act), the Clean Air Act, the Clean Water Act, the Toxic Substance Control Act,
the Marine Protection, Research and Sanctuaries Act or State criteria
applicable to the sludge management method being used;
(xi) any pollutant, including oxygen
demanding pollutants, released in a discharge at a flow rate and/or pollutant
concentration which will cause interference with the water board's
POTW;
(xii) any discharge of
pollutants which result in the presence of toxic gases, vapors or fumes within
the water board POTW or MS4 in a quantity that may cause acute worker health
and safety problems.
(2)
The occurrence of discharge of wastewater under emergency conditions and the
spillage of wastewaters in quantity or quality not in accord with the
provisions of this section shall be reported by telephone to the water board
POTW treatment plant duty operator immediately. Such occurrence or spillage
shall be confirmed by letter to the director within five working days when
requested by the director at the time of the telephone report or later by
written request (SIUs must report according to section
1960.6
of this Part). Persons responsible for the discharge shall take all available
means to reduce the volume and rate of discharge and shall cooperate with water
board personnel to reduce potential damaging effects.
