ADDITIONAL REGIONAL STAFF REVIEW ITEMS On May 7, 2020, WSRO staff made a site visit for review of the subject facility related to application for permit renewal. Jamie Cosson (YMCA), Chip White, ORC (Envirolink), and David Burton, BU-ORC (YMCA) accompanied staff on the site visit. Overall, the system appears to be maintained and in working order. However, there were several concerns noted during the site visit which warrant a WSRO follow-up inspection. Below is a summary of notes from observations made during the site visit. 1. The current permit has a schedule condition that required a freeboard gauge shall be installed within 60 days of permit issuance. However, no measurement gauge has been installed to date. Onsite representatives (including the primary and backup ORCs) offered to demonstrate the manual measurement method that is currently being used but were unable to do so. Recommend that this schedule condition be included in the renewed permit with a 60-day timeframe for installation. WSRO staff will conduct an onsite follow-up inspection to ensure this is completed. Average daily influent flows have exceeded the permitted max daily design flow during peak operations (mainly summer months). The remainder of the year the reported average daily flows are compliant. The facility is aware of the issue and has been working towards a solution. A flow equalization basin which would allow timed flow may address this issue. The facility has reportedly taken the following actions thus far: • Purchased neighboring property for potential expansion of the system, • Had a preliminary soils evaluation completed on the exiting property and the new neighboring property to evaluate potential permitting options. • Hired an Engineer to evaluate the potential for connection to public sewer, which reportedly is located within 1 mile of the facility. Facility representatives indicated that the sewer connection is their 1 It choice. They now are considering potentially expanding the camp with the new property that was purchased. FORM: WQROSSR 04-14 Page 2 of 3 DocuSign Envelope ID: ABA6B73A-7FDD-4879-8985-981D52780E7B 3. The reported 12-month loadings, and hourly loadings have exceeded the permitted limits for hourly and annual loading. Facility representatives indicated that this was the result of a computer dosing system error which resulted in overloading. This also resulted in some irrigation zones (e.g. zone #3) being used more heavily than others. Reportedly the issue has been corrected. The area adjacent and downslope of the irrigation zones was reviewed during the site visit. No evidence of runoff was observed, but irrigation was not being conducted at the time. WSRO staff to follow-up to ensure loading limits have returned to compliance. It should be noted: based on the past 12-months NDMR/AR reporting data the Plant Available Nitrogen (PAN) loading to the drip zones is greater than the agronomic limits for the irrigation areas. This data suggests PAN loadings in excess of 560 lbs. PAN/acre/year has occurred at times. If loading rates greater than agronomic limits continues, groundwater monitoring requirements should be considered and nutrient loading reporting on NDMLR forms should be required. 4. Review of the soil sampling results from the most recent 4 years (i.e. 2017 — 2020) suggests that there may be issues with Exchangeable Sodium Percentage (ESP) in the drip zones. ESP values reported in these results are elevated with values reported from 6% to as high as 47%. ESP values of 10 — 15% or higher can result in reduced infiltration and permeability of the soil. Recommend that WSRO staff request an effluent sampling event for Na, Mg, and Ca to evaluate the Sodium Adsorption Ratio (SAR) of the effluent. Also, a follow-up inspection with detailed review of drip should be conducted. Review soil sampling method & sampling depth should also be conducted to ensure proper samples are collected which are representative of the irrigation zones. A split sample event could be considered. FORM: WQROSSR 04-14 Page 3 of 3 Site Map WQ0019782 j L +' H 4 ZONE No.1ZONE 2 �� LAGOON ,.Fy 81 TA /F T .
