Salinity Regulations
On March 7, 1978, the Colorado Water Quality Control:
Commission adopted the "Regulation for Implementation
of the Colorado River Salinity Standards Through the NPDES
Permit Program." The first step towards complying with
the regulation for this permit will be monitoring for
salinity on a monthly basis for the first six months.
Thereafter, monitoring will be on a quarterly basis.
Monitoring will be required at both the raw water intake and
at the wastewater discharge. Analysis for salinity may be
either as Total Dissolved Solids (TDS) or by electrical
conductivity where a satisfactory correlation with TDS has
been established. The correlation should be based on a
minimum of five (5) different samples.
If the salinity monitoring program indicates an incremental
increase of salinity over 400 mg/1 during the first six (6)
months, a study will be made to determine if the excess
increase is correctable. The permittee will have 180 days
to complete the study and make the necessary corrections or
submit the justification necessary for a waiver. Sections
3.10.4 II A, B, and E of the salinity regulations outline
the criteria and information necessary to implement a waiver.
PRETREATMENT The permittee should refer to pages 15 and 16 for a discussion
of pretreatment requirements.
The permit shall expire on March 31, 1986.

A. MANAGEMENT REQUIREMENTS
1. Change in Discharge
All discharges authorized herein shall be consistent with the terms
and conditions of this permit. The discharge of any pollutant
identified in this permit more frequently than or at a level in
excess of that authorized shall constitute a violation of the permit.
Any anticipated change in discharge location, facility expansions,
production increases, or process modifications which will result
in new, different, or increased discharges or pollutants must be
reported by submission of a new NPDES application or, if such changes
will not violate the effluent limitations specified in this permit,
by notice to the State Water Quality Control Division of such changes.
Process modifications include, but are not limited to, the introduction
of any new pollutant not previously identified in the permit, or any
other modifications which may result in a discharge of a quantity or
quality different from that which was applied for. Following such
notice, the permit may be modified to specify and limit any pollutants
not previously limited.
2. Noncompliance
(A) Definitions
(1)
Upset: An exceptional incident in which there is unintentional
and temporary noncompliance with technology-based permit
effluent limitations because of factors beyond the reasonable
control of the permittee.
(2) Bypass: The intentional diversion of waste streams from any
portion of a treatment facility.
(3)
Severe Property Damage: Substantial physical damage to property,
to the treatment facilities to cause them to become inoperable, or
substantial and permanent loss of natural resources which can
reasonably be expected to occur in the absence of a bypass. It
does not mean economic loss caused by delays in production.
(B) Notification
(1)
113
If, for any reason, the permittee does not comply with or will be
unable to comply with any maximum discharge limitations or
standards specified in this permit, the permittee shall, at a
minimum, provide the Water Quality Control Division and EPA with
the following information:
a) A description of the discharge and cause of noncompliance
b) The period of noncompliance, including exact dates and times
and/or the anticipated time when the discharge will return to
compliance; and
c) Steps being taken to reduce, eliminate, and prevent recurrence
of the noncomplying discharge.
PART II

OTHER REQUIREMENTS (Continued)
Percentage Removal Requirements (Applies to Sewage Treatment Plants only)
If not presently being complied with, effective as soon as reason-
able and practical, but no later than immediately, the arithmetic
mean of the total BOD5 concentration for effluent samples collected
in a period of 30 consecutive days shall not exceed 15 percent of
the arithmetic mean of the concentrations for influent samples

OTHER REQUIREMENTS (Continued)
Within three (3) months after the effective date of this permit, a flow -measuring
device shall be installed to give representative values of effluent volume
at some point in the plant circuit, if not already a part of the wastewater
plant.
The following locations of flow -measuring devices are required:
1. Facilities with detention times within the treatment system of 24
hours or less: on the influent or effluent line, or within the system.
2. Facilities with detention times within the treatment system of 24
hours or more: on the effluent line.
If permittee desires to locate a flow -measuring device in a location other than
in 1 or 2 above, then permittee shall submit a request to the Division giving
the specific location (by map). The request shall include a justification that
the location will give accurate measurements within ten (10) percent of the
actual flow being discharged. Installation shall be subject to approval by the
Division prior to installation.
At the request of the Regional Administrator of the Environmental Protection
Agency or the Director of the State Water Quality Control Division, the permittee
must be able to show proof of the accuracy of any flow -measuring device used in
obtaining data submitted in the monitoring report. The flow -measuring device
must indicate values within ten (10) percent of the actual flow being discharged
from the facility.
The limitations stated in PART I, Section A, are calculated on the basis of
gross measurements of each parameter in the designated discharge regardless
of the quantity and quality of these parameters in the plant flow unless
otherwise specified.
If the permittee desires to continue to discharge, he shall re -apply at least
one hundred -eighty (180) days before this permit expires.
Within sixty (60) days of the effective date of this permit, the permittee shall file
a statement with the Environmental Protection Agency and the State Water Quality
Control Division which shall contain the names of the person or persons who are
designated to report conditions as noted in PART II, Section A, Paragraph 2a
(Noncompliance Notification), and as noted in PART II, Section B, Paragraph 7
(Oil and Hazardous Substance Liability). The permittee shall continually update
this list as changes occur at the facility.
The permittee is required to submit an annual fee as set forth in Section 25-8-502
C.R.S. 1973 as amended. Failure to submit the required fee is a violation of this
permit and will result in the suspension of said permit and enforcement action
pursuant to Section 25-8-601 et. seq., 1973 as amended.
Discharge Point(s)
Discharge points shall be so designed or modified that a sample of the
effluent can be obtained at a point after the final treatment process and
prior to discharge to State waters.

in toxic amounts as defined under Section 307(a) of the Clean Water
Act of 1977 (Federal Register dated January 31, 1978)or is found by
the permit issuing authority to have a significant impact on the
treatment works or the quality of effluent from the municipal treatment
works. The permittee shall monitor and analyze these industrial inputs
on a routine basis, and shall submit the results to the Division of
this ongoing monitoring effort at six (6) month intervals on June 30th
or December 31st of each calendar year.
B. The permittee must notify the Division of
by new or existing sources or any substantial
from any industrial source. Such notice must
described in "A" above and be forwarded no
following the introduction or change.
C. Pollutants introduced into the treatment facility by any source of
a nondomestic discharge shall not inhibit or interfere with the operation
or performance of the facility. The following pollutants may not be
introduced into the facility:
any new introductions
change in pollutants
contain the information
later than sixty (60) days
1. Pollutants which create a fire or explosion hazard in the facility;
2. Pollutants which will cause corrosive structural damage to the
facility, but in no case discharges with pH lower than 5.0, unless
the facility is specifically designed to accommodate such discharges:
3 Solid or viscous pollutants in amounts which will cause obstruction
to the flow in sewers, or other interference with the operation of
the facility;
4. Any pollutant, including oxygen demanding pollutants (BOD, etc.)
released in a discharge of such volume or strength as to .cause
interference in the facility;
5. Heat in amounts which will inhibit biolocical activity in the facility
resulting in interference, but in no case heat in such quantities
that the temperature at the treatment facility influent exceeds 40°C
(104°F) unless the facility is designed to accommodate such heat.
D. In addition to the general limitations expressed above, more specific
pretreatment limitations have been and will be promulgated for specific
industrial categories under Section 307 of the Act, including but not
limited to, those listed below. Compliance with these regulations is
required no later than three (3) years following the date of promulgation:
(See 40 CFR, Subchapter D, Parts 400 through 500, for specific information).

E. At such time as a specific pretreatment limitations become applicable to
an industrial contributor, the permit issuing authority may, as appropriate,
do the following:
(1) Amend the NPDES discharge permit to specify the additional
pollutant(s) and corresponding effluent limitations(s) consistent
with the applicable national pretreatment standards;
(2) Require the permittee to specify, by ordinance, contract, or
other enforceable means, the type of pollutant(s) and the maximum
amount which may be discharged to the permittee's facility for
treatment;
(3)
Require the permittee to monitor its discharge for any pollutant
which may likely be discharged from the permittee's facility,
should the industrial contributor fail to properly pretreat its waste.
The permit issuing authority retains, at all times, the right to take legal
action against the industrial contributor or the treatment works, in those
cases where a permit violation has occurred because of the failure of an
industrial contributor to discharge at an acceptable level. If the permittee
has failed to properly deilneate maximum acceptable industrial contributor
levels, the permitting authority will look primarily to the permittee as the
responsible party unless the contributor's discharge is obviously unaccceptable
under 40 CFR, Subchapter D - Water Programs.
