I presented my credentials to Mr. Joaquin Murillo, City of Las Cruces' Deputy Director Wastewater/Utilities and informed him 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 Las Cruces' representatives, observations made by the EPA inspector, records and reports maintained by the permittee (Las Cruces), and the EPA. Before leaving the facility on May 5, 2025, an exit briefing was held with Mr. Murillo, to explain areas of concern noted at the time of the inspection and discuss the Capacity Management Operations and Maintenance (CMOM) checklist forwarded via electronic mail (email) earlier in our discussion (Appendix 1 Capacity Management Operations and Maintenance Self-Assessment). FACILITY DESCRIPTION The City of Las Cruces-East Mesa Wastewater Treatment Facility (East Mesa) (WWTF) is classified as a minor discharger with a design capacity of 1 million gallons per day (MGD) and an average daily flow of domestic wastewater of 0.3 MGD from the east mesa side of Las Cruces. The facility is located at 5150 E. Lohman Avenue, Las Cruces, Dona Ana County, New Mexico (denoted in Aerial Image #1 below). The collection system also allows for influent to be redirected to the Jacob Hands WWTF (NM0023311) in an emergency. The East Mesa treatment process is comprised of a gravity collection system, and 2 lift/pump stations (Identified in Table 1 below). Influent enters the facility to be treated by a mechanical drum screen and a spray wash. Screenings are collected at a compactor station for disposal. The facility has two identical treatment trains (east and west). Influent enters a selector tank followed by two (2) first stage aeration tanks. A "block out" in the aerator tank can be operated to allow wastewater to flow to the second stage aeration tank. Solids from the first stage of aeration tank can be sent to a digester tank (two digester tanks available). Thence wastewater flows through an inlet to a rectangular clarifier. Return Activated Sludge (RAS) is sent through a trough and gravity fed back into the aeration basin, thence flow is sent to disc filter. The backwash from the disc filter is pumped back to the headworks for reprocessing. After the filter drums, flow enters the UV (ultra-violet) system comprised of 4 banks for disinfection, which currently operate continuously, thence the disinfected effluent is split to either a 2 million gallon holding tank for reuse or discharges via the outfall via a closed conduit pipe at Outfall 001 into the Southfork Arroyo, thence to the Alameda Arroyo, thence to the Las Cruces Lateral, thence to the Rio Grande. Note: East Mesa maintains a discharge permit (DP-1536) issued by the New Mexico Environment Department (NMED), Groundwater Quality Bureau (GWQB) that allows a discharge up to 1.4 MGD. Additionally, the WWTF discharges intermittently (once or twice monthly between November to February) when reuse water is not needed. Las Cruces, through the Discharge Permit, is authorized to use reclaimed water for irrigation at the Sonoma Golf Course along with other city owned properties. 2 City of Las Cruces/ East Mesa WWTF Permit No. NM0030872 Inspection Date 05/05/2025 Bio-solids from the WWTF are also sent to the digester at Jacob Hands (NM0023311). Produced digester gases are sent to the co-generation (CoGen) System. The Jacob Hands bio-solid waste is small volume distributed to the public with excess transported to the West Mesa WWTF for composting.

A review of the City of Las Cruces-East Mesa completed CMOM Self-Assessment: Collection System Information (page 3)- indicates 2 lift or pump station (identified above), and approximately 500-miles of gravity sewer lines. The CDM (f/k/a Camp Dresser and McKee) Master Plan indicates that approximately one-third (1/3) of the total piping, equate to or are greater than 10-inches in diameter, are less than 20-years old and that greater than three-fourths (3/4) are less than 30-years old. The Plan further states most of the piping is constructed of vitrified clay pipe (VCP) and polyvinyl chloride pipe (PVC) with the VCP being more common in sewers with diameters less than 15 inches in diameter. Other pipeline materials in this system include cast iron, ductile iron, and reinforced concrete. Note: the WWTF commenced construction circa April 2008 as such some of the CDM Master Plan information might not be applicable. A review of the City of Las Cruces-East Mesa completed CMOM Self-Assessment: Engineering Design (ED) (page 5)- indicates their engineering group involves staff for any comments or concerns with design, surveys are completed prior to construction and taken into consideration during design and planning, and television camera reports are available for all new installation of gravity sewer lines.
