Dear Ms. Dunn:
We have reviewed the Sylmar MHP Site Application which you sent us and provide
the following comments:
1) The site application will be reviewed by our board for a recommendation to
the State WQCD after Weld County has completed its review and made its
recommendation.
2) At this time the treatment plant proposal appears acceptable and to be the
best option.
3) We will need some additional details on the design of safety features for the
plant and lift station before we will be able to make our recommendation to
the State. These features would be those necessary to prevent a discharge
of untreated wastewater to the river in the event of operational problems
occurring, such as a power failure.
Thank you for the opportunity to comment.
Sincerely,

This Department has reviewed the proposed design for. the Sylmar Manor Mobile Home.
Park Onsite Wastewater Treatment System and determined it to be generally
acceptable. However, the following areas are of concern to the Department and
we are requestingthat they be addressed:
l). The proposed location is on Parcel 3, which the applicant does not
own. This Department is aware that there is an easement agreement
for Parcel 3 and has seen a copy of the easement agreement.
Although the agreement appears to be complete. in providing for this
project and for an undefined length of time, this Department would
like assurances that the applicant will have access to the site for
repair, maintanence and operation of the sanitary sewer system -for
the expected life of the system.
2). The method of disinfection of the effluent proposed is an Ultra
Violet (UV) system. This Department is concerned that there is no
secondary monitoring proposed to ensure that the (UV) system is
functioning properly between weekly monitorings.
Should you have any further questions regarding this matter, please feel free to
call. Pam Smith at (303) 353-0635, extension 2238 or Jeff Stoll at (303) 353-0635,

SCOPE
This report presents the results of an evaluation of the existing
onsite wastewater treatment system and presents a proposal for upgrad-
ing the system for SYLMAR MOBILE HOME PARK (Sylmar), located in SW/4,
Section 31, Township 1 North, Range 66 West, of the 6th P.M., Weld
County, Colorado, as indicated on Figs. 1 and 2. The report is intend-
ed to address the requirements of the Application For Site Approval
for submittal to the COLORADO DEPARTMENT OF HEALTH AND ENVIRONMENT
(CDOHE), Water Quality Control Division. Upon approval of the Site
Application, the design for the treatment system will be finalized.
SITE DESCRIPTION
The site is an approximate 11.24 acre parcel consisting of 3 par-
cels located in southwestern Weld County, Colorado, as indicated on
Fig. 2. The property is owned by Sylmar Ltd., Robert M. Sasner,
General Partner. Parcels 1 and 2 are owned by Sylmar Ltd. and Sylmar
Ltd. has an easement for use of Parcel 3.
Sylmar is an existing 104 unit mobile home park which includes 96
permanent spaces, 7 RV spaces and 1 house. Sylmar is immediately west
of US Highway 85, east of the South Platte River, and north of Weld
County Road 2 (168th). The site is northwest of the City of Brighton.
The majority of the mobile home park, Parcel 1, is located on the
2nd topographic terrace above the South Platte River at an elevation
of approximately 4965 feet. Parcels 2 and are 3 located on a lower
terrace with an approximate elevation of 4950 feet. The upper level
was developed as a mobile home park in the late 1960's. There are
mature trees at Sylmar. The lower western portions have sparse to
moderate vegetation. The South Platte River forms the west border of
the property, which is along the easement.
ZONING - Zoning within a 1 mile radius of the site is agricultur-
al, industrial, or residential as indicated on Fig. 3. Adjacent
zoning is agricultural, commercial and industrial.

WATER AND SANITATION DISTRICTS WITHIN A 5 MILE RADIUS - There are
3 Sanitation Districts located within 5 miles of the site, as in-
dicated on Fig. 4. The City of Brighton Water and Sanitation Dis-
trict exists to the east of US Highway 85 and south of Baseline
Road. The other water and sanitation district is the Town of Fort
Lupton, 4.5 miles to the north. There is a water only district at
the Wattenberg Improvement Association 3 miles to the northwest.
WATER SUPPLY INTAKES AND SEWAGE TREATMENT PLANTS WITHIN A 5 MILE
RADIUS - The public wells within 5 miles of Sylmar belong the
City of Brighton, as indicated on Fig. 5. Brighton has 6 wells
within 1 mile of the proposed discharge point. The Brighton sew-
age treatment plant is 2000 feet upgradient of the proposed Syl-
mar plant and is closer or equi-distant to 4 of the 6 Brighton
wells as the proposed Sylmar plant. The closest sewer connection
to Sylmar is located approximately 200 feet east of the southeast
corner of Sylmar at an 8 inch Brighton sewer line, or 200 feet
east of the northeast corner of Sylmar at an 8 inch Brighton
Sewer line. The existing sewer lines are 800 to 1000 feet up -
gradient and across US Highway 85 from the proposed plant.
WELLS WITHIN 1 MILE - There are 312 water wells registered with
the Colorado State Engineer in the 4 sections within 1 mile of
Sylmar. Because of the volume of paper, the State Engineer's
well records are not attached, but are available from our office
upon request. The closest wells are the onsite Sylmar wells
located approximately 130 feet east of the proposed treatment
facility. The closest offsite well is a residential well 860
feet to the north as indicated on Fig. 2. The listing of the
City of Brighton wells within a 1 mile radius registered with the
Colorado State Engineer is presented as Appendix A.
100 YEAR FLOOD PLAIN - The site is located adjacent to the South
Platte River and an application for a Flood Hazard Development
Permit has been applied for as presented on the application in
APPENDIX B, prepared by Tuttle/Applegate Inc.
GEOLOGIC SETTING - The site is underlain by near -surface alluvial
deposits underlain by claystone bedrock of Tertiary Denver Arapa-
hoe Formation. Basic geologic references for the area include:
Geologic Map of the Denver 1X2 Decree Ouadranale, UGSG Map I-
1163; and the Geologic Map of the Boulder -Fort Collins -Greeley
Area. Colorado, USGS Map I-855. The references indicate 18 to 40
feet of alluvial material underlain by claystone/sandstone bed-
rock. The maps indicate ground water at depths of 5 to 30 feet.
The impact of geologic conditions is minimal because disposal
does not include subsurface discharge and treatment.
EXISTING DISPOSAL SYSTEM
The existing wastewater treatment system was installed and was
upgraded at some time in the past. There has been surfacing of efflu-
ent, and upgrading of the system is required by the Weld County Health
Department and the CDOHE. The existing system consists of septic tanks
950693
3
and disposal fields as presented on Fig. 2 which includes 5 septic
tanks and at least 2 disposal fields. The remnants of a large concrete
tank near the northeast corner of Parcel 3 is believed to have been a
storage tank, but has floated out of the ground and is not in use.
At this time effluent is: a. partially accepted by fields, b.
intermittently surfacing at a manhole in the western portion of Parcel
2, and c. discharging on low ground in Parcel 3.
PROPOSED FACILITY AND ALTERNATIVES
In addition to the proposed Sequential Batch Reactor (SBR),
several wastewater treatment alternatives have been considered.
Options range from the installation of innovative systems such as con-
structed wetlands, to connecting to the City of Brighton. A brief
analysis of the plausible alternatives is presented below.
CONNECT TO AN EXISTING TREATMENT FACILITY - The closest waste-
water treatment facility is owned by the City of Brighton. The
closest service is located approximately 200 feet east of the
southeast corner of Sylmar at an 8 inch Brighton sewer line. The
cost to install a sewer line this distance is estimated at $40/
foot which is $8,000. Additional costs would be sewer lines in
Sylmar of $29,600, and a lift station at $40,000, which does not
include the purchase of right-of-way which would be required. The
sewer tap (Development) fee in Brighton is $2500 per unit, which
would result in a fee of $260,000. The total cost of sewer con-
nection is estimated at greater than $340,000.00. If both water
and sewer were connected to Brighton, the cost is estimated at
$587,000 and would require annexation to Brighton. The Sylmar
property in not located in the City. An additional $800 per site
Development fee is being considered by Brighton, which would add
additional cost. Discussion with Charles Kiepe, Director of
Operations at the City of Brighton, indicate the city is not able
to provide both sewer and water service.
INSTALL NEW SUBSURFACE DISPOSAL FIELDS - Any system involving
subsurface infiltration of effluent is not possible due to set-
back requirements to wells and river based on the property owned
by Sylmar or which Sylmar has easements.
RECIRCULATING SAND FILTER TREATMENT (RSF) AND CONSTRUCTED WETLAND
SYSTEMS - RSF and Constructed Wetland technology were considered,
but were not selected based on the land area requirements which
are not available at Sylmar.

EXTENDED AERATION PACKAGE TREATMENT PLANT - Extended aeration
plants evaluated included: the NORWECO, INC. Modulair and SANTEC
wastewater treatment plants. We believe the treatment capabili-
ties of the extended aeration plants are comparable to the pro-
posed SBR system, however the aeration systems would require an
equalization basin and we believe would be more operation and
mailarl,tbutnwould have vmuch greater e. The inital cost is believed to be simi-
lar, maintenance costs.
PROPOSED SEQUENTIAL BATCH REACTOR TREATMENT SYSTEM
We are proposing the installation of a Sequential Batch Reactor
(SBR) as a new onsite treatment system to be located at Parcel 3 in
the western portion of the site as indicted on Fig. 6. A SBR manu-
factured by Case/Cotter is proposed as indicated at APPENDIX C. A
cost estimate for the SBR and maintenance is presented as TABLE III.
From the collection manhole indicated on Fig. 7, sewage will
gravity flow to a lift station to be pumped to the SBR plant. After
treatment at the SBR, an Ultra Violet (UV) trench will disinfect the
effluent. The effluent will discharged at a point source between the
plant and the South Platte River. Final design will be submitted upon
approval of the Site Application. As a part of construction existing
septic tanks will be bypassed, with the tanks abandoned inplace.
The effluent sampling and quality requirements will be set by the
Permits and Enforcement Section of the Water Quality Control Division
of the CDOHE. Anticipated quality requirements are presented in a
letter of March 15, 1994 from the Water Quality Control Division
attached as Appendix D. The effluent quality will be monitored.
ESTIMATED WASTEWATER FLOW RATES - The current population of the
mobile home park is 104 units which includes 96 permanent spaces,
7 RV spaces and 1 house. Water use records which have record main-
main-
tained since March 1994 as presented on TABLE I, ranged from
supplied the to facility. Monthly average
use
has r
eow o
36000 to 45717 gallons per day with average ran
f
41929 GPD. The peak day for each month is presented with the
peak day being in January of 1995 at ak 49400loGPD.
g oSyumarnwas sudin-
if-
ferent than anticipated, with the p to minimize foccurring
gzdug of
the winter when faucets are left open pipes at the mobile homes. There is also a high use in the spring
950698
for an unknown reason. A summary of daily use is presented as
TABLE II, which monitored five 3 hour periods plus overnight
flow. Actual sewage flow will be monitored at the new facility.
ESTIMATED COST - The estimated cost of the SBR is $125,000. The
installation of the treatment system will commence upon approval
of the Site Application and approval of the final design of the
SBR by the CDOHE.
OPERATION AND MAINTENANCE
A primary feature in selecting the SBR system is its relative low
operation and maintenance requirements. -An operator with a Class C
License is required.
Annual Maintenance Costs: Annual sampling and testing of efflu-
ent, permit fees, and pump replacement costs are estimated at
$8500 per year. It is anticipated operation and maintenance will
be provided through a contract operator until onsite personnel
have obtained their Class C License or a Class C License holder
is hired by Sylmar.
LIMITATIONS
Our investigation, layout, design, and recommendations are based
on information contained herein. If conditions considerably different
from those described in this report are encountered, we should be not-
ified to evaluate the effect of the conditions on the proposed treat-
ment system. We should be notified to review and approve any site
changes made during construction of the treatment system.
The long term effectiveness of the wastewater treatment system
depends not only on the design, but on the operation and maintenance
of the system. There should be continued professional involvement
with the operation and maintenance of the system.
If there are any questions, please call.
