Lucas Kamat, New Mexico Environment Department- Program Manager, Point Source Regulation Section-Surface Water Quality Bureau (NMED) arrived at the City of Artesia (Artesia) Wastewater Treatment Plant (WWTP) approximately 9:00 AM on September 22, 2021 for an unannounced inspection. I presented my credentials to Ms. Patsy Hernandez, Wastewater Supervisor and informed her that this was an EPA inspection to determine the facility's compliance under the Clean Water Act (CWA) and the requirements of the National Pollutant Discharge Elimination System (NPDES) permit program, in accordance with the CWA. The generation of this report is based on information supplied by Artesia representatives, observations made by the EPA inspector, NMED and records and reports maintained by the permittee (Artesia), and the EPA. Before leaving the facility on September 22, 2021, an exit briefing was held with Ms. Hernandez, and Ms. Lucas-Kamat to explain areas of concern noted at the time of the inspection. FACILITY DESCRIPTION The WWTP is a major discharger with a design flow of 2.6 million gallons per day (MGD). The original WWTP was built to treat approximately 1.3 MGD of wastewater (Train #1 built in approximately 2003). A second treatment train, identical to the original was built in approximately 2007; thus, increasing the facility capacity to the current 2.6 MGD. The facility is located at the intersection of New Mexico State Road 229 and State Road 357, Artesia, Eddy County, New Mexico (depicted in Aerial Image #1 below). The WWTP facility serves a population of approximately 12,000 residents. The WWTP is operated by staff within the Public Works Department and consists of 5 full-time equivalent (FTE) positions (2certified and 3-operators-in-training (OIT)), inclusive of administrative support during the hours of 6:00 AM to 4:00 PM during the regular work week and 7:00 AM to 9:00 AM on the weekends. On-call staff is available on an as needed basis. The city maintains 7 lift stations (Identified in Table 1 below).

According to WWTP records approximately 4,700 gallons of septage on average is received on a weekly basis. The facility staff monitors incoming registered septage haulers for pH and grease to determine compatibility with the WWTP for acceptance or rejection. At the head of the treatment plant, the influent is pumped into the first of two (2) automatic bar screens for large solids removal. Installation of an additional bar screen was necessary due to pumps being damaged by large solids. Most of the treatment units are situated above land surface due to the areas high static water level (SWL). Treatment units at the WWTP are comprised of two (2) bar screens and grit removal system at the headworks, followed by four (4) race-track design oxidation ditches, and extended air treatment units. The WWTP's existing grit chamber was rehabilitated in mid-2020. Each day, each race- track rotates through periods of anoxic and aerobic mixing and settling. The racetracks discharge to two (2) secondary clarifiers which discharge effluent to a filtration system which then feeds into three (3) independent banks of an ultraviolet (UV) disinfection system prior to discharge to the Pecos River or to a reuse pond for application in city parks. The onsite clarifiers are cleaned on a weekly basis. The WWTP also maintains an emergency high test hypochlorite (HTH) Chlorine/Sodium Thiosulfate system should the UV disinfection fail. Solids removed from the racetracks and/or the final clarifiers are sent to a thickener followed by a sludge press. Following UV disinfection, a Parshall flume with a staff gauge and a differential pressure sensor records the totalized flow. Part of the calendar year (approximately 7months) the disinfected effluent is stored for reuse on city parks and other facilities within an onsite clay lined storage pond or lagoon measuring approximately 6M-gallons. This storage pond or lagoon is permitted by the New Mexico Environment Department (NMED) Groundwater Quality Bureau under permit number (DP-258). During the months of November through March the WWTP discharges the treated effluent to the Pecos River. During the months of discharge at the outfall the disinfected effluent traverses through a closed conduit pipe approximately 1-mile prior to discharging into the Pecos River, , though there were no discharges during calendar years 2020 or 2021. A riprap structure has been placed at the outfall to minimize embankment undermining, prevent erosion and to enhance aeration prior to discharge into the Pecos. Following the belt press, the sludge is placed in concrete drying beds (underdrains return excess liquid to the headworks) for composting into Class A sludge for land application and/or local agricultural purposes. A Supervisory Control and Data Acquisition (SCADA) system provides around the clock monitoring of WWTP operations and is manned during normal working hours with alarm notifications in the off hours. The WWTP maintains a backup diesel generator for power that is exercised weekly, typically every Friday. 3 City of Artesia/Artesia WWTP Permit No. NM0022268 Inspection Date 09/22/2021 Aerial Image #1: Overall view of the City of Artesia's Wastewater Treatment Plant. Aerial from Google Earth maps. Currently the only established Industrial User (IU) is the Holly Frontier (Navajo Refining Company, LLCArtesia Refinery) (Navajo). The City of Artesia (COA) and Navajo entered into a wastewater agreement for the disposal of Navajo's effluent into the City's WWTP in 2013, which was updated in May 2014 to include selenium removal technology. In accordance with conditions of this Agreement, a WWTP (access only) sampling point and totalizing meter was installed within a locked building situated at the approximate southwest corner of North Freeman and East Logan Streets (Latitude/Longitude 32 51' 11.305" North 104 23' 45.142" West). WWTP personnel collect samples daily via an automatic sampler (auto-sampler) for pH and chlorine (CL) analysis. Additionally, the in-line filters installed before refinery flows enter the auto-sampler are inspected on a weekly basis. The Agreement allowed a discharge of industrial wastewater not to exceed 21,600 gallons per day (GPD) and a non-domestic wastewater discharge of not to exceed 216,000 GDP or a total combined discharge of not to exceed 237,000 GPD. The observed Omega type C7.00 meter (serial number 56448/17) is scheduled for calibration/certification on an annual basis. The Navajo-Artesia facility is used for "cracking" (thermal & catalytic cracking) in accordance with Petroleum Refining Effluent Guidelines and Standards (40 CFR Part 419). This process breaks large, heavy hydrocarbons from topping process into smaller hydrocarbons Section II - OBSERVATIONS I observed the following and the following information was provided and/or stated: The WWTP's grit chamber was rehabilitated in mid-2020. 4 City of Artesia/Artesia WWTP Permit No. NM0022268 Inspection Date 09/22/2021 An update to the previous 2014 wastewater agreement between the COA and Navajo is currently awaiting signature (approval) due to the current Renewable Diesel Unit (RDU) and Pretreatment Unit (PTU) project. In accordance with conditions of the Navajo and COA Agreement, a WWTP (access only) sampling point and totalizing meter were installed within a locked building situated at the approximate southwest corner of North Freeman and East Logan Streets (Latitude/Longitude 32 51' 11.305" North 104 23' 45.142" West). WWTP personnel collect samples daily for pH and chlorine (CL) analysis. The observed Omega type C7.00 meter (serial number 56448/17) is scheduled for calibration/certification on an annual basis. The WWTP on-site laboratory maintains and updates its written SOP's as necessary, inclusive of appropriate annual equipment certifications and/or calibrations. The WWTP had secure perimeter fencing; thus, limiting access. The overall WWTP's operations and maintenance (O&M), and general facility housekeeping appeared to be in good order.
