Ashland Ski Area Sewage Plant Issues Submitted within this packet is correspondence between the Oregon Department of Environmemat Quality (DEQ) and the Mt. Ashland Ski Area (MASA), which indicates that: · DEQ has cited the Ski Area sewage plant as being out ofcomphance with its permit (December 16, 2002). · The sewage plant permit has expired (May 31, 2003). With regard to the citation, MASA has offered a corrective plan to DEQ and will, presumably, be institming its measures, with its effect still to be observed. Of interest is that this plan institutes "Feeding the plant with activated sludge obtained from the City of Ashland wastewater plant" (Page 2, Step 2). MASA has applied for renewal of its sewage permit and has requested an easing of the terms of the permit to eliminate the basis of the earlier citation. We believe that this information should be public knowledge, and that the City Council and the City's citizens should be directly involved with negotiations relating to both the permit and its proposed alteration.

Hanson: On October 9, 2002, Rick Bl'ake and I met with you to inspect your waste water treatment t;aci[ities and review the elevated levels of Total Nitrogen reported on your 2001 Discharge Monitoring Repor~ (DMR). Your DMR reported th.at your wasmwater discharges contained Total Nitrogen concentrations ranging from 73.9 raga to 104.7 rog/l, which are signiticantl, y higher than your permitted discharge effluent limit et'net more than 10 mg/l as requSred in Schedule A of your permit. These elevated Total Nitrogen discharge concentrations are a violation of Oregon Revised Statutes (ORS) 468B,050(I) (c) and in accordance with our Entbrcement Rules contained in Oregon Administrative Rules (OAR) 340-012-055(2)(g) are Class 2 violations. The Total Nitrogen limit of l0 rog/1 was estaNished to ensure the ground, waters down gradient of your subsurface disposal fields would not be Lmpacted to where their current and future use a.s a potable source of drinking water supplies would be threatened. Your subsurthce disposal fields are located in the City of Ash. land's watershed and the groundwater flows from this area eventually Become part of Ashland's potable drinking water supply. Fortunately, to date the ground water monitoring you have conducted down slope of the disposal fields have not yet shown any indications of elevated nitrogen contamination. Accordingly, in order to address the above violations, we are askihg dmt by not later than March l, 2003, that you subndt a plan and corrective implementation schedule on what steps you will take to lower your Total Nitrogen concentration discNtrges to ach/eve compliance with your permitted discharge concentration limitations. As part of this plan, we sugge'~t you contact the firm who designed your current Sequent Batch Reactor treatment unit and have them evaluate why this unit is not pertbnning in accordance with Page 2 WRGPNON-02-05 12-16~02 the projections they submitted when the permit was orlglnnlly issued. The plan also needs to include the continuation of groand water monitoring until it can be shown that the Total Nitrogen discharge concentration limit can be maintained within permit requirements. Please submit this plan to my attention at the Grams Pass DEQ Office using the ad&ess on the above letter head. Exceeding a permit established effluent limit i~ a Cia.ss 2 ¼olatiort. Oregon Administrati. ve Rule (OAR) 340-12-041 (2)(c) provides that a permittee shall not receive more than three NONs for Class li violations of the same permit within a thirty-six (36) month period without being issued a more formal enforcement action called a Notice of Permit Violation (NPV). The Department may, however, issue an NPV prior to the third NON. II'you have any questions, or ifI may be o£ a~sistance to help you meet the March date, please contact me at (541) 471-2850- e~. 24.

Costanzo, RS DEQ Western Region Grants pass Branch Office 510 NW 4a' Street Grants Pass OR 9'7526-2019 Re: WRGPNON-02-05 Dear Mr. Costanzo: As requested, we are submitting, within this letter, our plan and corrective implementation schedule on our steps to lower the Total Nitrogen concentration limitations to achieve compliance with our permitted discharge concentration limits. To assemble this plan we have utilized the expertise on our own staff' (Oregon licensed plant operators Robert J. Corbit and Chester Tesh), Oregon licensed plant operators from the City of Ashland, a representative from the plant manufacturer (Targie Mandt of Fluidyne Corporation), as well as professional literature. According to the manufacturer" It is apparent that the SBR system has not met effluent nitrogen requirements during the sinter ski season. The very nature of this application makes it difficult to obtain nitrification because the plant is essentially fed during the cold winter months and starved the remainder of the year. There are several variables, all of which are interrelated, that directly affect the rate of nitrification." The steps below have been designed by considering each variable and effecting appropriate correction toward positively affecting the rate of nitrification. Step One - Mixing Pump - implemented in November, 2002 Objective o Provide sufficient contact time along with proper dissolved oxygen concentrations, · Action o A mixing pump was added to the SBR tank to increase the contact time of the nitrifying bacteria, lower the DO concentrations during the long static cycles, and generate more energy and heat. o In operation we maintain the DO from 0.0 mg/1 to 3.5mg/1 through sufficient aeration periods.

Additional procedures planned for November/December 2003. · Objectives o Provide improved conditions for initial plant operation © Provide a 'start np supply" of nitrifying bacteria · Action o Cleaning of the plant's "trash trap" © Feeding the plant with activated sludge obtained from the City of Ashland wastewater plant. © Additional procednre planned for Nov/Dec, '03: Supplementing bacteria with a commercial product containing nitrifying bacteria designed to assist nitrification in lower temperatures. Step Three - Increase water temperature in the treatment tanks - planned for implementation prior to start of November/December 2003 plant start up. · Objective o Increase water temperature, ideally to 50-55°F to activate nitrifying processes in the plant Actions o Enclose the area over the SBR and SAM tanks with an insulated metal building. This will require approval by the U.S. Forest Service. We will submit this action as part of our annual "Summer Work Plan". © Alter the aeration pump intake pipes to draw warmer air froln the top of the building. © Provide re-circulating fans in the building to keep warmer air in contact with the solution in the treatment tanks. o Installation of a new water heating system in the Lodge (the primary source of influent). The current tank type heater will be replaced with an instantaneons system capable of maintaining consistently higher hot water temperatures. © Monitor effects of the actions taken, and make corrections as needed, which may include direct heating in the tanks. Step Four - Utilize the City of Ashland lab capabilities for interim effluent diagnosis, · Objective o Use "mid-month" lab test results to make adjustments (to pH, nitrifying bacteria, etc.) to improve nitrification process prior to certified lab tests. · Aclion o Have effluent samples analyzed mid month and take appropriate action to improve nitrification. Step Five - Monitor pH and total alkalinity and maintain a higher range Objective © Provide sufficient alkalinity in the plant to oxidize the concentration of NH2 ammonia present in the treatment tanks. · Action © Monitor pH and total alkalinity daily and maintain recommended levels. Mt. Ashland Association Response to WRGNON-02-05 We plan to continue semi-annual groundwater monitoring until it can be shown that the Total Nitrogen discharge can be maintained within permit requirements. The monitoring is planned for the middle of the operating season (February) and after the operating season (May). Please contact us with any questions or comments you may have regarding this course of action. Sincerely, Encl. 2/12/03 Letter from Fluidyne Corporation 2~a Copy of this original letter Mt. Ashland Association Response to WRGNON-02-05 March 30, 2003 Chuck Costanza Department of IEnvironmental Quality 510 NW 4~h Room 76 Grants Pass OR 97526 Dear Chuck: Enclosed is our completed application and permitting fees for the renewal of WPCF-OS Permit No. 101662 at the Mt. Ashland SM Area on the Rogue River National Forest. As we discussed on the phone on Thursday, March 20, Ski Ashland is formally reqnesting changes to the permit, outlined below. PLEASE TAKE NOTE THAT SKI ASHLAND WILL FOLLOW UP THIS LETTER WITH A MORE SPECIFIC REQUEST WITH SUPPORT FROM OUR WASTEWATER ENGINEER. Change in groundwater monitoring requirements. We request that the permit reflects the gronndwater monitoring regimen proposed in our Februury 23, 2003 response to your notice WRGPNON-02-05. We proposed continuing semi-annual groundwater monitoring until it can be shown that tile Total Nitrogen discharge can be maintained within permit requirements, and proposed that monitoring schedule to be once in the middle of tile operaling season (February) and once after the operating season (May). Change the Total Nitrogen concentration limit to more accurately reflect the treatment capacity o1' tile Sequenciug Batch Reactor plant. We request that the Total Nitrogeu concentration limit be expressed in weight (kilograms or potmds)/month, and be based on the capacity of the plant, rather the current mg/L expression. Rationale: a. This Sequencing Batch Reactor is cun-ently permitted for the treatment of 15,750 gallons per day (peuk), The plant's actual average daily influent for treatmeut is approximately 1750 gpd with rare peak flows of approximately 5000 gallons, and operation with these flows for only 5 months per year. b. At the concentration limit ol' 10rog/L, the daily limit, expressed as weight of Total Nitrogen, at plant capacity, is approximutely [000% of that delivered at our average flow. c. As described on the groundwater monitoring report submitted to your agency itl December, 2002, the reqnired 27 months of groundwater monitoring indicated ubso[utely no groundwater contamination, despite tile over-limit Total Nitrogen conceutnltions at tile current below capacity flows.

The ongoing and planned chauges presented in the February 24 response to the WRGPNON-02 05 are anticipated to result in effluent with a lower total nitrogen concentration. See the respouse for details. 5. Review each condition of your current permit and attach a brief report that indicates your progress in meeting the requirements, limitations and compliance schedules of the permit. Schedule A 1. Waste Disposal Limitations a. The maxi[num flows are well below those permitted. Permitted peak folw is 15,750 gpd. The average daiJy flows have been between 1,200 gallons and 2,300 gallons (expressed as the average daily flows per month). The peak daily flows have generally been about 5,000 gallons. b. The plant has consistently (over 90% of the time) met the concentration limits for BOD~ and TSS. c. The plant has consistently not met the concentration limits for Total Nitrogen. This was discnssed in detail in our Febrnary 24, 2003 response to Notice of Non~ Compliance WRGPNON-02-05. Due primarily to seasonal operation and cold treatment temperatures, total nitrogen concentrations have averaged 78 rog/l, but approach the 10mg/l concentration limit at the end of the operating season when the plant chemistry has "matured". We are confident that the measures taken and planned, as described in tile responses to the NON, will improve this. Our groundwater monitoring regimen, taken over 27 months, showed no effect from the treatment system, We will separately be requesting a change in the total nitrogen limit on the new permit. d. Native plants and grasses have been planted, and have naturally regenerated, in the drainfie/d areas, although disposal is primarily in the winter season when there is snow cover. 2. N/A 3. The existing Phase I large on site system has not been nsed dnring flows over 2000 gpd. Schedule B 1. (a, b,c) All requirements, paramenters and lkequencies have been inet. (d) All preventative maintenance activities have been consistent with the operations manual 2. Monitoring reporting has been completed in accordance with this reqnirement. 3. Gronndwater monitoring was performed in accordauce with the Groundwater Monitoring Plan. 4. Monitoring did not indicate a significanl increase in value for a monitored parameter, so ilo action was required trader this requirement.

June 24, 2003 Chuck Costanza Department et' Environmental Quality 5[0 NW 4tl~ Room 76 Grants Pass OR 97526 Dear Chuck: JUN 2 ? 2003 St~le of Or~oc~ - D.E.O. We~iern Reg~o~. Grarits Pas~ This is an addendum to our application fbr the renewal of WPCF-OS Permit No. 101662 at the Nit. Ashland Ski Area on the Rogue River National Forest. As noted within the original application of March 30, and discussed with you on the phone, we're fbllowing up with a more specific permitting change request regarding the Total Nitrogen level based on consultations with your staff and our wastewater plant engineer. For Schedule A - Disposal [.imitations - I b. We request that thc renewed WPCF petTnit set an annual Total Nitrogen limit of 480 pounds per year in the effluent to the disposal field. This would replace the maximum concentration requirement of 10mg/I Total Nitrogen. Rationale: 1. The maximum permitted daily flow from the treatment facility is presently 15,750 gallons per day. On an annual basis, thc Total Nitrogen discharge at full capacity, at 10 rog/L, calculates to be 480 pounds. 2. This limit is consistent with the allowable maximum daily flow from the plant. 3. At the actual discharge levels fbr the past operating year, the Total Nitrogen sent to the disposal fields was approximately 151 pounds for the year of June 1, 2002-May 30, 2003. 4. The required 27 months of groundwater testing (which is continuing now on a twice per annum basis) has consistently shown no groundwater effects from treatment system, despite some effluent Total Nitrogen concentrations above our present pcrmitted level of 10 mg/I. This confirms that effective nitrogen removal is occutTing in the drainfield portion of the treatment system in addition to within the treatment plant. 5. The closest perennial surfhce water downstream from the drainfield is approximately 1.5 miles in distance, assuring further and complete treatment (should it even be necessary) long belbre any potential contamination of any water supply. 6.
