ATTACHMENT TO SITE APPLICATION
In accordance with C.R.S. 1981, 25-8-702 (2)(a), (b), and (c), and the "Regulations for Site
Applications for Domestic Wastewater Treatment Works•, the Water Quality Control Division mu
determine that each site location is consistent with the longrange, comprehensive planning f
the area in which it is to be located, that the plant on the proposed site will be managed t
minimize the potential adverse impacts on water quality, and must encourage the consolidatio
of wastewater treatment works whenever feasible.
In making this determination, the Division requires each applicant for a site approval for a
domestic wastewater treatment works to supply an engineering report describing the project a
showing the applicant's capabilities to manage and operate the faility over the life of the
project to determine the potential adverse impacts on water quality. The report shall be
considered the culmination of the planning process and as a minimum shall address the
following:
Service area definition including existing population and population projections,
flow/loading projections, and relationship to other water and wastewater treatment plant
in the area.
Proposed effluent limitations as developed in coordination with the Planning and Standar
Section of the Division. (Allow minimum four weeks processing time.)
•
Analysis of existing facilities including performance of those facilities.
Analysis of treatment alternatives considered.
Flood plain and natural hazard analysis.
Detailed description of selected alternatives including legal description of the site,
treatment system description, design capacities, and operational staffing needs.
Legal arrangements showing control of site for the project life.
Institutional arrangements such as contract and/or covenant terms for all users which wi
be finalized to accomplished acceptable waste treatment.
Management capabilities for controlling the wastewater throughout and treatment within t
capacity limitations of the proposed treatment works, i.e., user contracts, operating
agreements, pretreatment requirements.
Financial system which has been developed to provide for necessary capital and continued
operation, maintenance, and replacement through the life of the project. This would
include, for example, anticipated fee structure.
Implementation plan and schedule including estimated construction time and estimated
start-up date.
Depending on the proposed project, some of the above items may not be applicable to address.
In such cases, simply indicate on the application form the non applicability of those.

The Town of Carbondale is a municipality and provides wastewater management
services, including collection and treatment to its constituents. The Town owns the
property where the present and proposed wastewater treatment facilities are located.
The Town of Carbondale provides wastewater service to its constituents along with
other typical municipal services (i.e., domestic water, police protection, roads, streets,
parks, alleys, etc.
The management structure is typical for municipalities and includes as Board of
Trustees over a Town staff, which consists of a Town Manager and Water &
Wastewater Supervisor who supervises the day to day activity of the plant operators
for the wastewater treatment facility. The Town of Carbondale Municipal Code
governs the rules and regulations for users of the wastewater treatment facilities.
The Town operates the wastewater system through the enterprise fund accounting
method. Tap fees or system improvement fees area collected for new users tying onto
the system. Monthly service fees are assessed to all dischargers and property taxes
are paid through mill levy assessment. This project will be funded through cash
reserves within the wastewater enterprise fund and/or through bonds.
