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. |

The Discharger has discharged waste (wastewater) to surface water (Pila Creek) without authorization from an NPDES permit. This is a violation of Compost General Order Prohibition 6. The Industrial General Permit (IGP) is a stormwater permit and does not authorize the discharge of wastewater, which is defined above. IGP requirements and potential violations are not discussed in this letter. |

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.? |

Order Conditions |
The Discharger has not adequately reported events of noncompliance or notified Central Coast Water Board of all Compost General Order violations, such as notification and reporting of wastewater discharges from the Facility, including the wastewater discharge resulting from the January 9, 2023, storm event. The Compost General Order includes reporting requirements including estimating the volume of wastewater when there is a discharge, which must be submitted in a report to Central Coast Water Board staff within 10 working days of noncompliance. This is a violation of Compost General Order Monitoring and Reporting section B.3 and Compost General Order Notification Requirement 4. |

Order Conditions |
The cover damage and slope failure on the Phase 1 final cover failed during a storm event that was less than the 100-year, 24-hour storm event and therefore violates General Order Specification C.11. The Discharger must make repairs to address the underlying issue that caused the slope failures and cover damage in a timely manner to come into compliance with the General Order conditions. The Discharger must also take steps to prevent additional cover damage and limit potential water quality impacts from percolation into the unlined waste footprint, prevent waste exposure, and prevent stormwater impacts from mobilized sediment. |

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. |
