APPLICATION FOR SITE APPROVAL FOR CONSTRUCTION OF:
A NEW DOMESTIC WASTEWATER TREATMENT PLANT
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 must determine that each site location is consistent
with the long range, comprehensive planning for the area in which it is to be located, that the plant on the proposed site
will be managed to minimize the potential adverse impacts on water quality, and must encourage the consolidation 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 and showing the applicant's capabilities to
manage and operate the facility 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 and projected population, site location, staging or phasing, flow/loading
projections, and relationship to other water and wastewater treatment plants in the area.
Proposed site location, evaluation of altemative sites, and evaluation of treatment alternatives.
Proposed effluent limitations as developed in coordination with the Division.
Analysis of existing facilities within the service area(s).
Analysis of opportunities for consolidation of treatment works in accordance with the provisions of 22.3(1)(c),
including those recommended in the water quality management plan, unless the approved water quality management
plan recommends no consolidation.
Evidence that the proposed site and facility operations will not be adversely effected by floodplain or other natural
hazards. Where such hazards are identified at the selected site, the report shall describe means of mitigating the hazard.
Evidence shall be presented in the form of a report, containing soils testing results and design recommendations and
prepared by a Professional Geologist and a Geotechnical Engineer, or by a professional meeting the qualifications of
both Professional Geologist and Geotechnical Engineer, with an appropriate level of experience investigating geologic
hazards, stating that the site will support the proposed facility.
Detailed description of selected alternatives including legal description of the site, treatment system description, design
capacities, and operational staffmg needs.
Legal arrangements showing control of site for the project life or showing the ability of the entity to acquire the site and
use it for the project life. Approval by the Division of an application for site approval shall not be deemed to be a
determination that the proposed treatment works is or is not necessary, that the proposed site is or is not the best or only
site upon which to locate such a treatment works, or that location of a treatment works on the site is or is not a
reasonable public use justifying condemnation of the site. Approval by the Division shall only be deemed to be a
determination that the site application meets the requirement of this regulation 22 (5 CCR 1002-22).
Institutional arrangements such as contract and/ or covenant terms which will be finalized to pay for acceptable waste
treatment.
Management capabilities for controlling the wastewater loadings within the capacity limitations of the proposed
treatment works, i.e., user contracts, operating agreements, pretreatment requirements and or the management
capabilities to expand the facilities as needed (subject to the appropriate, future review and approval procedures).
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.

Proposed Wastewater Treatment Facility
CDOT, Bair Ranch Rest Area
Garfield County, Colorado
Job No. 12090
Mr. Bair,

APR 2 : 71e3
GARFIELD COUNTY
BUILDING a PLANNING
As requested by the Colorado Department of Public Health and Environment (CDPHE), Grand Junction
office, CHURCH & Associates, Inc. (CHURCH) has prepared this Addendum to the subject report. The
Engineering Report for Site Approval, Proposed Wastewater Treatment Facility at the CDOT Bair
Ranch Rest Area (Rest Area) was prepared under CHURCH Job No. 12090, dated December 15, 2002.
This Addendum was prepared to provide additional information requested by CDPHE.
Existing and Proposed Wastewater Treatment: Additional commentary regarding the justification for the
proposed wastewater treatment facility (WTF) installation was requested. The existing waste handling
devices at the Rest Area consist of composting toilets for the solid wastes, and a septic system to handle
wastewater generated from sinks and the composting toilets. The composting toilets are located in the
basement of the Rest Area restroom building. Due to the operating and maintenance demands of the
composting toilets and anticipated increase in use of the Rest Area in the future, replacement of these
toilets with standard flush toilets is preferred by CDOT. The flush toilets will be connected to the
proposed WTF as outlined in the Site Application report. The composting toilets will be dismantled and
removed from the Rest Area and the existing septic system absorption bed will be abandoned. A similar
conversion from composting toilets to flush toilets and a similar WTF has already been completed at the
Grizzly Creek Rest Area.
Preliminary Effluent Limits (PELs): CHURCH received PELs prepared by Ms. Karen Young, Permits
Unit, Water Quality Protection Section, WQCD at CDPHE, a letter dated January 29, 2002. A copy of
the letter is provided with the Site Application Report. CHURCH was informed by Ms. Young, that the
PELs for the proposed WTF presented in the letter are still applicable.
Other items requested from CDPHE (Grand Junction):
1. Attached is a Revised Figure 6 that presents revised locations of the proposed WTF components and
the minimum setback distance (100 feet) from occupied buildings at the Rest Area for the proposed
WTF. The revised locations of the WTF components vary from those locations presented in the
DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033
303.463.9317 Fax: 303.463.9321
original Site Application report. The new WTF component locations are in the vicinity of those
locations originally proposed. The changes are a result of the design process.
2. Attached is a photograph of the public notice sign that is currently installed at the Rest Area
regarding the proposed WTF.
3. Attached are the signed Application for Site Approval for Construction of: A New Domestic
Wastewater Treatment Plant forms from: CDOT, Garfield County, and the Two Rivers Water and
Sanitation District.
