INSPECTION SUMMARY A Compliance Evaluation Inspection was conducted on August 10, 2011, by Herschel Biasing of the MPCA to determine the facility's compliance with the terms and conditions of its NPDES/SDS Permit. The following is a summary of the findings and comments resulting from that inspection. Areas of Concern or General Comments: • Overall Physical Condition of the plant appears to be in excellent working condition. The operators keep things in good working order and strive in day to day operations and maintenance trying to achieve full compliance. • Sampling Methods/Lab Certification -compliant • All required reports have been submitted complete and on time for the review period. • At the time of the inspection the city of Elk River (City) was in the process of installation of new collection tine coming into the main headworks of the treatment facility. The duration of this project may result in problems this fall if biosolids land application is necessary. The City may need to work with the road contractor on truck traffic during this time. • The facility is designed to handle an influent average wet weather flow of 2.2 million gallons per day (mgd). For the review period of January 2010 through June 2011 the facilities average flow has been 1.2 mgd. • Enforcement Actions over the review period -none. • Compliance Schedule progress-The current permit includes a chapter for the required submittals for the facility upgrade. • Biosolids/Land Application Sites-compliant. • General Maintenance Schedule Reviewed -Daily, Weekly and Monthly O&M -compliant. • Record Keeping -compliant. • As part of the inspection, MPCA staff met with Mr. Leirmoe and Mr. Femrite to discuss the possibility of the City expanding their collection line north to several cluster system developments. Most of these cluster systems are within current City limits, located adjacent to each other, and are currently contributing high nitrates to groundwater. These systems were not designed to adequately wastewater for nitrates. Many of these cluster systems that have NPDES/SDS Permits with the MPCA are coming up for reissuance, once these are reissued, the permits may contain compliance schedules that will require nitrate limits. Because the cost for these cluster systems to upgrade to advanced wastewater treatment to meet nitrate levels will be extremely costly, it may be in the best interest of all parties, to hookup to City treatment. • If the City would be interested in extending collection to the cluster systems, the MPCA would like to set up a meeting with all parties to discuss the future of potential collection and treatment at the City's wastewater treatment facility. • For the review period of January 2010 through June 2011 the City had one effluent violation. For the monitoring period of August, 2010 the City reported a Maximum Calendar Week Average CBOD of 307.50 kg/day with a limit of 157 kg/day. No effluent violations have taken place since this time. • Please be aware that the City's current NPDES/SDS Permit expires on November 30, 2012. This current permit requires the City to submit to the MPCA on or before 180 days of permit expiration a • Pollutant Minimization Plan • Phosphorus Management Plan • Results of third or final acute test battery • Results of the third and final sampling event for priority pollutants (no later than one year prior to the expiration date of the current permit). • Application for permit reissuance 3
