Copper, Total Daily Maximum limit is 9 ug/L and reported value was 13.4 ug/L at EFF-001. |
Elevated total dissolved solids, total organic carbon, and chemical oxygen demand in the CMU wastewater have generated sludge through the pretreatment process faster than the ATS can process it. The excess sludge has resulted in the ATS operating at reduced throughput or in batch mode, backing up water, and has allowed solids to carry over from the inclined plate settler, blinding the filters and reducing UV transmittance, and degrading treated effluent quality. While treatment was paused, wastewater was periodically routed back into the ADF as percolate makeup water. Corrective actions were initiated in March 2026 and are anticipated to be completed by July 31, 2026:
-Sludge management: deploying dewatering bins and mobilizing geotubes to the site to remove sludge handling as a bottleneck. The County is currently finalizing the dewatering plan so that treatment of the stored CMU wastewater can resume.
-Settling tank upgrades: upgrading the primary and secondary settling tanks to better handle the high volume of solids.
-Piping modifications: adding a skimmer in the settling tanks to reduce solids carryover to the media filters, and relocating chemical dosing further upstream at the ATS for additional settling time.
-Pretreatment coagulant dosing: implementing coagulant dosing at Tank 2 to increase settling time and improve pretreatment before water enters the ATS.
-UV system repair and filter maintenance: replacing the malfunctioning instruments within the control panel to restore UV disinfection and performing maintenance on the UV system and the sand and carbon filters.
-CMU Capital Improvement Project: a longer-term project kicking off in July 2026 will address CMU deck drainage inlet improvements and repair the valve between the CMU deck and the CMU lift station.

Order Conditions |
Facility feedstocks listed in the notice of intent and Technical Report are green material and anaerobic digestate. The Compost General Order requires that anerobic digestate be derived from allowable Tier 2 feedstocks. Additionally, the Compost General Order defines anerobic digestate as, “the solid portion of the material remaining after the anaerobic digestion of any combination of agricultural materials, biosolids, sewage sludge, food materials, green materials, manure, paper materials, or vegetative food materials. Dewatered digestate contains organic matter that may need to be further treated to stabilize it, usually through aerated composting.” The Compost General Order prohibits any feedstock, additive, or amendment other than those specifically described in the Compost General Order, unless approved by the Regional Water Board. Based on information provided by the Discharger via email on March 15, 2023, and presented in the March 13, 2023, inspection report including the March 15, 2023, email as attachment 1 and inspection photos, feedstock at the site contain significant amounts of inorganic contaminates including glass and plastics, which are not approved feedstocks, additives, or amendments, nor are these materials compostable. This is a violation of Compost General Order Prohibition 3 and 4 and Specification 7. The Discharger must comply with the Compost General Order and ensure that only approved feedstocks are stored and/or composted at the Facility. For a full list of approved Tier 1 and 2 feedstocks allowed in anerobic digestate, please see Compost General Order Table 2.” |
The Discharger must address the alleged violations described above immediately and must submit by April 3, 2023, a written response describing the actions taken or planned to address the above alleged violations and prevent future violations. For violations that the Discharger has not addressed immediately, the response must include a time schedule for corrective actions to bring the compost Facility into compliance with the requirements of the Compost General Order. |

Order Conditions |
The Discharger discharged feedstock and compost outside of the designated composting operation areas that are specified in the technical report. This is a violation of Compost General Order Prohibition 1 and Specification 4. This includes compost found under the conveyer system that connects the anerobic digestion facility (ADF) to the compost Facility, as documented in the March 13, 2023, inspection report. This includes compost found on the densitometer table working surface area, which according to the approved technical report, was designed to include a berm surrounding the working surface to prevent compost impacted wastewater from discharging from the Facility. The lack of berm installation was documented by the Discharger in a February 8, 2023, report. Central Coast Water Board staff did not approve this report as an official technical report addendum and responded to the Discharger via email on February 8, 2023, indicating concerns about wastewater potentially discharging from this area. This correspondence as well as documentation of compost/waste on the densitometer table working surface, is included in the March 13, 2023, inspection report. |

Order Conditions |
The Discharger has not managed wastewater in accordance with the Facility’s approved Water and Wastewater Management Plan, which is a violation of Compost General Order Specification 6. These violations include not implementing the following procedures included in the approved Water and Wastewater Management Plan:
a.
The Water and Wastewater Management Plan indicates that before bypassing runoff from the compost working surface as clean stormwater, operators would first fully cover the compost with waterproof tarpaulins, place wattles between compost rows, and sweep the isles between windrows. During recent runoff diversion, the compost windrows and piles were not fully covered, the aisles were not fully swept to remove compost/waste from the exposed working surface areas, and wattles were not placed between all windrows. Thus, working surface runoff from the March 10, 2023, storm contacted compost/waste, which discharged from the Facility as wastewater. Mustang Renewable Power Ventures, LLC staff and County staff indicated that this water was diverted during the March 10, 2023, storm to the north sedimentation basin, which ultimately discharged to Pila Creek.
b.
The approved Water and Wastewater Management Plan indicates that wattles would be placed at the stormwater drainage inlets at all times. During the March 13, 2023, inspection there were no wattles surrounding the northern drainage inlet.
c.
The approved Water and Wastewater Management Plan includes requirements to sample and test each time runoff is bypassed to the Landfill north sedimentation basin instead of being captured as wastewater within the onsite tanks. Based on conversations with Mustang Renewable Power Ventures, LLC staff and County staff, samples were not taken during previous diversion events where water was discharged to the Landfill north sedimentation basin as required by the approved Water and Wastewater Management Plan, such as diversion during the January 9, 2023, storm event. Another diversion event, where samples were not collected, occurred during the December 27-29, 2021 storm event, which was documented in the March 2022 Annual Report. Conversations with the Mustang Renewable Power Ventures, LLC staff and County staff indicate that there may be additional bypass/discharges after work hours because there are no sensors, flow meters, or other triggers to alert operators of an overflow or bypass. |
The Discharger must address the alleged violations described above immediately and must submit by April 3, 2023, a written response describing the actions taken or planned to address the above alleged violations and prevent future violations. For violations that the Discharger has not addressed immediately, the response must include a time schedule for corrective actions to bring the compost Facility into compliance with the requirements of the Compost General Order. |
