'T 1'7ACILIT.' ESCAL ON, SAN JOA QUIN COUNTY Enclosed is a report summarizing my 14 August 2001 inspection of the City of Escalon wastewater treatment facility. In general, the wastewater treatment plant was clean and well maintained; however, violations of the waste discharge requirements (ADRs) were observed. A site inspection photograph log is enclosed with this letter. On 10 August 2001, a citizen complained of offensive odors that exist in the early morning and late evening in the nearby Del Rio residential development. As part of the facility inspection, the Del Rio residential neighborhood was visited at approximately 9:30 am prior to arriving at the wastewater treatment plant. On the date of the inspection, no offensive odors were noted in the Del Rio neighborhood. Upon arriving at the wastewater treatment plant, the Mosquito Abatement representative was leaving the site. Mosquito Abatement District representatives frequently monitor the site to determine if the wastewater facility is a source of mosquitoes. The representative was satisfied that mosquito fish placed in the wastewater ponds are controlling the mosquito larvae population. The City expanded the wastewater treatment facility in year 2000 to accommodate industrial wastewater generated by Escalon Packers and Eckert Cold Storage. On the date of the inspection, the facility had been receiving industrial wastewater for approximately six weeks, and many of the industrial wastewater ponds had not yet been used. The following observations were noted during the inspection: • Industrial wastewater was being delivered to the wastewater treatment plant. • Freeboard in the industrial treatment and disposal ponds was acceptable. • Objectionable odors were not noted during the site inspection, even adjacent to the industrial wastewater treatment ponds.
