Subject: West Hill n Park 5th Filing - S449
Dear Ms. Daniels-Mika
In April Case S449 was scheduled before the Planning Commission for hearing on the
Preliminary Plat. At that time we requested a continuance to allows us to address issues
concerning Hill n Park Sanitation District. The issues have been addressed as follows:
• The City of Evans has taken over the Sanitation District
• Issues regarding Manhole overflow - any sanitation district will have an occasional plug-
up and overflow,that appears to be the case here. When problems have been identified
they are promptly handled. We do not have a record of a recant overflow. There was a
case of an accidental discharge related to some construction at a manhole and that has
been taken care of. Several instances over the past 3 years have involved an individual
homeowner with a personal lift station. These back-ups were a result of the homeowner
not paying attention or maintaining the lift station. We have contacted the homeowner
and he understands and agrees that part of the connection from the Main to his home is
his responsibility,this includes the lift station.
• Hill n Park Sanitation and the City of Evans met with the State of Colorado Department
of Health concerning issues related to the facility. As a result of this meeting a number of
things have been done; increased aeration, upgraded chlorine facility,new flow meter,
removed trees, other compliance issues addressed, and general maintenance.
• City of Evans has determined that the system has the capacity to accept these lots and has
issued taps for them. Should the subdivision not proceed these taps can be transferred to
other locations.
Since these issues appear to have been addressed, we feel we are in a position to proceed with the
review of the preliminary plat.

Re: Hill N' Park Wastewater Treatment Capacity
Dear Mike:
As requested, I would like to respond to your request for confirmation that adequate capacity
exists within the Hill N' Park Wastewater Treatment Plant to provide service to twenty proposed
single family lots in West Hill N' Park, Fifth Filing.
As described in the attached letter from the Colorado Department of Public Health and
Environment, it is up to District officials, in this case the City, to determine If additional taps can
be connected. By virtue of adopting the enclosed Supplemental intergovernmental Agreement,
the City confirms that adequate capacity exists.
The current plant capacity of the Hill N' Park wastewater treatment plant is 0,336 million gallons
per day(MOD) and the present average flow is 0.26 MGD, thus there Is sufficient capacity to
accommodate near term development Proposed Improvements within the next two to three
years are planned to Increase the capacity to 0.4 MOD. Long term plans are to increase the
ultimate capacity to 0.9 MOO, which is sufficient to handle a majority of the development west of
the current City. It is the City's intent to undertake long tens improvements as soon as
Practicable.
Hopefully this information meets your needs. If you have any questions, please coil me at 339-
5344 (110).

Dear Mr,Pickett:
This is in response to your Ismer of May 4, 1998 regarding the Hill-N-Park Sanitation District operations. In your letter you
request that the Water Quality Control Division (the Division) approve the connection of an additional 20 taps.
Pursuant to Colorado Law, C.R.S. 25-8-501 (Sd &e), the permiltee(in this case HW-N-Petit Sanitation District) is requited
to initiate engineering and Onastelal planning for expansion of the wastewater Revetment facilities whenever throughput and
treatment reaches eighty(g0)percent of design capacity. Whenever throughput and treatment reaches ninety-five(95)percent
of the design capacity,the pemtlmsa shall commence construction of the necusuy treatment expansion.
According to your analysis.it appears that the District's facilities have not reached the 50 percent capacity,therogere,it is up
to the District oMaids to decide if they want to approve the connection of an additional 20 taps. In addition, its the owner's
responsibility,or its agent.to meet discharge permit limits.
As we discussed during out recent telephone conversation, I have scheduled an inspection for June 2, 1998 to evaluate the
District's compliance with its discharge permit limits. At this point I would appreciate it if you would provide the following
information regarding this system's permk compliance: a)Your design owluatien for Tsui detention,b)detention time for each
cell, c) aeration capabilities for the total system, d) influent waste load,a) effluent quality, C chlorine chamber contact time,
g)independent sampling you mentioned during our phone conversation,and any other information that may help me to perform
a detailed evaluation of this system's ability to meet its discharge permit limits.
If you have any questions or comments,please call me at(303)692-3564
