BEA is responsible for the Wastewater Treatment Plant operation and maintenance duties, and for maintaining compliance with permit requirements, including but not limited to, fulfilling sampling program requirements and monitoring groundwater quality. The following annual report has been prepared to summarize the overall treatment plant status and detail the 2023 sampling results, as well as any treatment operation issues experienced, and modifications made. During the 2023 operating period, the above referenced facility had no reportable exceedances. Total nitrogen concentrations were reported at or below 5.0 mg/L in 67% of the effluent samples collected, with an average total nitrogen concentration of 4.20 mg/L for the 2023 monitoring period. All other parameters subject to permit limitations under SE 746-1 were reported below their respective limitations throughout 2023. As such, it is evident the treatment plant continues to provide excellent treatment and operates to design specifications. Regularly scheduled and routine maintenance of the system, including pumping of tanks, maintenance of UV components, and inspections of blower components, and other electrical and mechanical components were performed during the 2023 operating period. Based on the results of the monthly effluent laboratory analysis, and the regularly scheduled and routine maintenance performed during the 2023 operating period, it is the opinion of BEA that the wastewater treatment system servicing Pleasant Bay Health and Living Centers continues to perform optimally.
