As we discussed, some additional tnform·atfon fs required fn order for the· letter of intent (LOI) submitted by Aspen Consolidated 5ani.tation District and the User Plan ta Comply submitted by the City of Aspen to be considered mmplete. Specifically, for the letter af intent to be·«Dn51'dered complete, the followin1 infonnation is required: 1. Either a copy of the site application approva( letter and the approval letter for the reclaimed water treatment facility plans .and specifications; or evidence of ·sLibmittaC of ·a -site application and plans and spedffcatfons to the division (.Regulation 84.6.A.2); 2. The E. coli monthly geometric mean for January 2015; 3. E. coli and turbidity·data for February 2015 (data for February 2014 was mistakenly included); 4. E. coli and turbidity data for Au1ust 2015; 5. Effh.1ent turbidity d~ta. for mmparison to Ca~egory 2 standards; 6. Po1nt of compliance dar:i'ficatfon. As I mentionedy "point of compliance" is defined by 84.5(19) as a point Identified by the treater fn the reclaimed watcer treatment or transmission system after all treatment has been a>mpleted and prior to dtluttpn and blending. The LOI fndtcates that there may be·blendtng of raw wate..r and red.aimed watef in the impoundment, howewr, you stated on the phone that th~re may not be blendina. PleMe researdt this issue and let me know whether the facility plans to 'blend raw water with reclaimed Wi\t er in the golf oourw impoundment. Also, as I mentioned' on the phone, I wanted to diSQISS the proposed E.coli point of compliance with Liz Lemonds, who has compliance oversight for the reclaimed water proaram. Based on our discussion, since the E.coli limit is established for protection of human health, it must be met prior to potential human contact. Is the tmpoundment at the golf a>utse a water huard or are·there other instances where golfers or other members of the public may have contact with water in the impoundment? For the user Plan to mmply to be considered complete, please submit specifications for the liner for the impoundment located at the 1olf course and/or results of a seepaae rate study for the impoundment. Liz also menttoned that ~me· facilities that have SW1td'ted from raw Water to reclaimed Water have seen rtsh kills in the past because the change can be a Shock to the fish. She·recommended tha:t if this use is approved, that City of Aspen add reclaimed water to the pond gradually (e.g. 101 increase each day), to try to preserve the trout stocked in the impoundment. This is .not something that we would regulate but we wanted you to be aware of this infonnation. I have cc'd Liz on this email in case·you have questions for her related to this specific topic. Plea.se let me know if you have any questions or a>ncerns ~lated to any of the fnfOrmatton in this email.

We understand that Aspen Golf Club is a certified Audubon sanctuary. Reclaimed water, depending on nutrieht content, may contribute to growth of blue green algae, which may in ~me instances produce toxins. It is really difficult to predict what, if any, impact this could have on the bird population. However, we wanted you to share this thought with you for your evaluation. Thanks, Maureen [Quoted laxt hidden] Bruce Matherly To: "Egan - CDPHE, Maureen" Cc: Steve Altken Mon, Apr 11, 2016 at 10:23 AM Maureen, Thank-you for the feed back on our fetter of Intent and user plan to comply. Steve and I w'ill begin working on answering your questions right away. We appreciate your willingness to allow us to provide additional information as questions arise. We think reuse could be a great way to irrigate the golf course and it could be a great example of water reclamation (provided it makes economic sense). The only way we can determine if it is economically practical is probe along and see what concerns CDPHE has and then determine how we can address those concerns. We appreciate your patience.
