Respondents operate the Santa Teresa wasteater treatment plant. The plant is an old plant, built around 1979, that is hydraulically and organically overloaded. EPA inspected the facility on Nov. 11, 2003, and found the facility to be in serious violation of the NPDES program, including poorly operated equipment and the City failing to even have proper NPDES permit coverage. The facility is in New Mexico, but the discharge goes into a drainage ditch in Texas and flows through a residential subdivision on the way to the Rio Grande river. E. coli and many other pollutants have been found in this ditch and the Health Dept. has issued bans on human contact with the water in the ditch. This Order requires the City to obtain an NPDES permit and bring the facility into compliance with the NPDES program.
