14.This Order establishes compliance schedules below that address anticipated future violations of final effluent limitations for enterococci and total coliform bacteria. In accordance with Water Code section 13385 (j)(3)(B) and the terms of this Order, MMPs will not be assessed for violations of the final effluent limitations for enterococci and total coliform bacteria during periods of treatment plant flows greater than 1.1 MGD as stipulated in Finding 11 above. Specifically, the Regional Water Board finds that:
a. This Order is being issued after July 1, 2000 and specifies the actions the Permittees are required to take to correct the violations of Order No. R1- 2023-0039.
b. The Permittee is unable to consistently comply with the new disinfection effluent limitations related to enterococci and total coliform bacteria because new or modified control measures are needed to achieve compliance, and the new or modified control measures are necessary and dependent on the completion of a series of studies, thus the new or modified control measures cannot be designed, installed, and put into operation within 30 calendar days.
c. This Order establishes interim effluent limitations for disinfection criteria and establishes a compliance schedule for bringing the Facility into compliance with final effluent limitations for enterococci and total coliform bacteria in the Permit that are as short as possible.
d. Provisions 6.3.2.1 of the Permit require the Permittees to develop and conduct a Pollution Minimization Program to identify and control pollutant sources including, but not limited to, enterococci and total coliform bacteria at the Facility.
15.Accordingly, the Regional Water Board finds that MMPs for violations of final effluent limitations when discharging to the Pacific Ocean at Discharge Point 001, as measured at Monitoring Location EFF-001 and as specified in Effluent Limitations sections 4.1.1.3.1 and 4.1.1.3.2 of the Permit do not apply for enterococci and total coliform bacteria during months when the Facility’s flow exceeds 1.1 MGD and requires operation of the rotating biological contactors.
This exception applies through April 1, 2030, provided the Permittee complies with the interim effluent limitations contained in this Order. If an interim effluent limitation contained in this Order is exceeded, then the Permittee is subject to MMPs for that particular exceedance, as it will no longer meet the exception in Water Code section 13385(j)(3)(B)(i)(ii).

16.The compliance schedule established in this Order is intended to be as short as possible. This Order provides a compliance schedule for the Permittee to investigate why they have been unable to comply with their effluent limitations for enterococci and total coliform bacteria and identify and implement corrective actions to come into compliance with the final effluent limitations for these parameters.
17.This Order requires the Permittee to comply with interim effluent limitations for disinfection. The SIP requires that interim effluent limitations for pollutants be based on past performance or limits in previous orders, whichever is more stringent. Interim effluent limitations for total coliform and Enterococci established in this Order were derived based on Facility performance using available effluent monitoring data at Monitoring Location EFF-001, the point of discharge to the Pacific Ocean. These performance-based interim effluent limitations were calculated using statistical methodology described in the U.S. EPA Technical Support Document for Water Quality-based Toxics Control (TSD) and a statistical tool, RPCalc, developed by State Water Resources Control Board staff to assist State and Regional Water Board staff in the development of interim effluent limitations. The 95th percentile concentrations of each pollutant were calculated at the 95 percent confidence level to determine interim Maximum Weekly Effluent Limitations. The calculated limitations were rounded to the nearest whole number:
Table 1: 95th Percentile Concentrations for Interim Effluent Limitations Parameter Units Maximum Weekly Effluent Limitation
Total Coliform Bacteria MPN/100 mL 939
Enterococci MPN/100 mL 610
The interim limitations in this Order are intended to ensure that the Permittee maintains at least its existing performance while investigating the necessary means and implementation of prevention measures to improve performance of their disinfection system to the extent possible and completing all tasks required by the compliance schedules. The Permittee remains subject to the permit’s final effluent limitation for fecal coliform, thereby ensuring that current performance for this parameter is maintained.
18.The Regional Water Board has notified the Permittee, interested agencies and persons, of its intent to issue a Time Schedule Order in accordance with Water Code section 13167.5.
19.Issuance of this Order is exempt from the provisions of the California Environmental Quality Act (Pub. Resources Code, § 21000 et seq.) (“CEQA”) pursuant to CWC section 13389, since the adoption or modification of a NPDES permit for an existing source is statutorily exempt and this Order only serves to Time Schedule Order - 7 - DRAFT

The Regional Water Board’s Executive Officer has delegated their authority under Water Code section 13323 to issue this Complaint to the Assistant Executive Officer.
1. The City of Crescent City Wastewater Treatment Facility (Facility) is a publicly owned treatment works (POTW), located at 210 Battery Street in Crescent City, Del Norte County, California. The Facility is currently regulated under WDRs Order No. R1-2023-0039, replacing Order No. R1-2017-00021. The orders serve as both NPDES permits and as waste discharge requirements for discharges from the facility.
2. The Regional Water Board adopted WDRs Order No. R1-2017-0002 (2017 Order) on February 2, 2017, and it became effective on April 1, 2017. The Regional Water Board adopted WDRs Order No. R1-2023-0039 (2023 Order) on December 12, 2023, and it became effective on February 2, 2024. The 2017 Order and 2023 Order established, among other things, final effluent limitations for the discharges from the Discharger’s permitted discharge location, Discharge Point 001.
3. Section IV.A. of the 2017 Order and Section 4.1 of the 2023 Order contain, in part, the following effluent limitations for Total Coliform, Enterococci, Ammonia Nitrogen, Total (as N), and Chlorine, Total Residual with which the Discharger is required to maintain compliance at Discharge Point 001:

WAIVER FORM
FOR ADMINISTRATIVE CIVIL LIABILITY COMPLAINT
By signing this waiver, I affirm and acknowledge the following:
I am duly authorized to represent The City of Crescent City (Discharger) in connection with Administrative Civil Liability Complaint No. R1-2025-0034 (Complaint). I am informed that California Water Code section 13323, subdivision (b), states that, “a hearing before the regional board shall be conducted within 90 days after the party has been served [with the complaint]. The person who has been issued a complaint may waive the right to a hearing.”
OPTION 1: Check here if the Discharger waive the hearing requirement and will pay the liability in full.
a. I hereby waive any right the Discharger may have to a hearing before the North Coast Regional Water Quality Control Board (Regional Water Board). b. I certify that the Discharger will remit payment for the proposed civil liability in the full amount of two hundred twenty-eight thousand ($228,000) by submitting a check that references “ACL Complaint No. R1-2025-0034” made payable to the Accounting Office, Attn: ACL Payment Accounting Office, PO Box 1888, Sacramento, California, 95812-1888, and a copy of the check to the Regional Water Board within 30 days from the date on which this waiver is executed.
c. I understand the payment of the above amount constitutes a proposed settlement of the Complaint, and that any settlement will not become final until after a 30-day public notice and comment period. Should the Regional Water Board receive significant new information or comments from any source (excluding the Regional Water Board’s Prosecution Team) during this comment period, the Regional Water Board’s Assistant Executive Officer may withdraw the Complaint, return payment, and issue a new Complaint. I understand that this proposed settlement is subject to approval by the Regional Water Board, and that the Regional Water Board may consider this proposed settlement in a public meeting or hearing. I also understand that approval of the settlement will result in the Discharger having waived the right to contest the allegations in the Complaint and the imposition of civil liability.

Features & Benefits
Overview
In today’s modern wastewater treatment plants, meeting high standards in effluent quality, cost efficiency and odor control is a must. To meet these higher standards, JWC introduces the Bandscreen Monster, a member of the Monster Separation System line of high performance screens.
This system offers incredibly high capture rates and is able to remove a wider variety of solids, particularly small solids and trash, better than traditional screens. It is frequently specified to protect high-tech Membrane Bioreactors (MBR) so they can run more efficiently and with less maintenance.
The rotating panels are positioned parallel to the flow and as wastewater enters the screen it flows left or right through the perforated screening panels. Panels available with 5/64”, 1/8” or ¼” (2, 3 or 6mm) openings. The heavy-duty stainless steel roller chain passes around a UHMW guide track to eliminate the need for sprockets or bearings in the flow.
Unwanted solids are captured and lifted to the discharge level where a spray system washes solids into the Screenings Washer Monster® for washing, dewatering and compacting.
Flow passes through the left,
right and bottom panels.

1 Sanitaire® Silver Series II Diffusers
THE FINEST FINE BUBBLE DIFFUSER FOR BIOLOGICAL TREATMENT For a combination of high aeration efficiency and low operating costs, choose the Sanitaire Silver Series II membrane diffuser – the most widely used fine bubble diffused aeration system available today.
High oxygen transfer efficiency
The Sanitaire Silver Series II membrane design uses a unique slit pattern and slit shapes to provide fine, uniform air distribution across the whole membrane surface. This allows the diffusers to deliver optimal oxygen transfer efficiency across the diffuser operating range.
Long service life, low maintenance
The high elasticity and degradation-resistance of specially blended high-grade EPDM elastomer compounds contribute to a service life of 10 or more years.
Operating efficiency
The unique membrane shape with integrated O-ring creates a top seal with the threaded retainer ring to eliminate leakage.
This reduces energy consumption and raises
operating efficiencies.
Great application flexibility
A highly effective, integrated check valve
enables the aeration zones to easily be shut
down for air-on/air-off applications.
Sanitaire Silver Series II LP
This 9” low-pressure version of the
Sanitaire Silver Series II membrane features
a modified slit pattern to handle airflow
up to 20.4 Nm³/h (12 scfm) with minimal
pressure loss. It is an excellent choice for
sludge and other heavy-duty applications.

Notes:
i. Exposure to chloramines is not recommended in feeds below 6.5 pH. ii. Maximum available filtration TMP is based on a number of variables including atmospheric pressure, module submergence depth and filtrate pump NPSH requirement. The actual value may vary slightly from that shown. iii. The recommendation for maximum chlorine cleaning solution concentration is to account for an initial rapid consumption of chlorine at the start of a MW or CIP cleaning cycle. The targeted chlorine cleaning solution concentration is then typically 200 to 1000 ppm for the remainder of the cycle. iv. Please consult DuPont Water Solutions for additional guidance on exposure limits and for operation at different temperatures. v. Parameters are subject to change without notice.

ASSEMBLY DETAILS
Notes:
i. When Membrane Filtration Modules are fitted to the MemRACK® Assemblies, the transport, storage and operating limits of the membranes determine allowable limits of exposure. Please refer to the relevant Module specification sheet for further details. ii. Mass estimates are for MemRACK® Assemblies loaded with Modules and filtrate side substantially filled with water. The mass will be greater if the Modules are heavily soiled.
iii. Some alternative materials of construction may be recommended for seawater or other high TDS applications.

2. About WavTexTM
WavTex is a second generation moving media system using Entex’s patent pending EnTextile™ media for use in Integrated Fixed-film Activated Sludge (IFAS) and Submerged Fixed-Film (SFF) systems. Independently moving EnTextile media sheets continually wave in the aeration basin in a random motion, ensuring excellent oxygen and substrate transfer.
WavTex is a cost-effective solution for existing activated sludge plants that need more advanced treatment. Because little or no additional tankage is required, WavTex is ideal for plants with limited room for expansion. It is also an excellent choice for space efficient, high performance new plant designs.
WavTex moving flex media provides extensive surface area for biomass growth. The attached biomass population can more than double the effective MLSS concentration. The vigorous motion of the EnTextile media in the aeration basin provides a high shear on the surface of the EnTextile media, maintaining a thin biological film. The thin film provides for high rate biological kinetics.

VAREC BIOGAS 231 Series
GAS/ FOAM SEPARATOR
The 231 Series Gas/Foam Separator is designed for use in piping systems to remove foam typically caused by agitation from the digester discharge gas.
Design Features
• All stainless steel construction
• Continuous spray wash system
• Removes foam and particulates
• Alarms for high and low water levels
• Large reservoir with baffle
GAS CONTROL
Introduction
The Varec Biogas 231 Series Gas/Foam
Separator is designed for use in piping
systems to remove foam typically caused by
agitation from the digester discharge gas.
The foam must be dispersed and collected in
order to protect downstream equipment from
corrosion or clogging. The Gas/ Foam
Separator is typically installed in the gas
piping as it exits the digester.
Construction
The main vessel is welded 316L stainless
steel construction and is available in either 2
foot or 3 foot diameter vessels.
The inlet and outlet gas connections are
ANSI 150 FF flanges. The size is determined
by the actual pipe size of the digester gas
line. The water inlet connection is a 3/4” NPT
connection. Drain connections are 4”, ANSI
150lb flat face flanges.
The unit is equipped with a NEMA 7 level
switch for high and low water level alarms.
High level alarm is connected to a NEMA 7
solenoid valve located on the water supply
line.
The water spray manifold is stainless steel
pipe and fittings, welded at all joints.
Maximum working pressure is 1 psig (27.7”
WC). Consult factory for special dimensional
requirements.
Operation
Entrained foam and solids are removed from
the gas as it flows through the device. This is
accomplished by subjecting the gas/foam
mixture to a direct spray of water inside the
chamber. The gas must then rise vertically
past an internal baffle in order to flow from
the tank.
Foam and solids are heavier than gas, and
the combination of the large vertical rise the
gas has to travel, and the continuous spray of
water will knock the foam out of the gas and
direct it to the bottom of the chamber. The
foam is removed via a drain connection.
Liquid level switches allow for high and
low-level alarms to be connected to the plant
system. At low water condition, source power
is routed through the low-level switch to
terminals for plant connection of a low water
alarm. If for any reason the water level in the
tank rises above the high water float switch,
source power is routed to terminals for plant
connection of a high water alarm and the
spray water solenoid valve is de-energized
which stops the water flow into the unit.
