RE.: I. S. D. S. Evaluation 987 U. S. Highway 85
To Whom It May Concern:
The following is our report for the evaluation of subject I. S. D. S.
1. The latest pumping receipt is attached. The tank is reported to be
1,000 gallon. This is meets the requirements for this application..
2. We have found no record of any permit for subject system. The
firm that pumped the system recorded the information used to
•
evaluate the system. The owner at the time of the installation is
now deceased.
3. We have performed percolation tests in the vicinity of the field to
evaluate the system. We stayed approximately 10' from the field to
obtain, what we feel, are more representative data. The percolation
rate for this area is 17.2" per inch.
4. The following criteria was used to evaluate this system:
The facility consists of an office only.
There are 5 employees working at this site.
There are no public facilities at this site.
Potable water,is brought into this facility. The well is used only for
washing and flushing the toilet.
Q = 5 employees X 20 gallon per day = 100 G. P. D.
10 Visitors X 6 gallon per day = 60 G. P. D.
Design Q = 1.5 X calculated Q = 1.5 X 160 = 240 G. P. D.
Required Area =
A = QX1/T'/ 3.5 = 240XY:17.213.5 = 120X4.16 /3.5 = 285 S. F.
•
P.O. BOX 552 e ERIE.COLOR__DO 80516 e 255 KA1_t ELL ST= (30_)288-x168
• Existing field is 2 - 50' long legs. 100 L. F. trench at 3' wide = 300
S. F of percolation field. This is adequate for the required field.
5. I have inspected the septic system and found no evidence of any
malfunction in the system at this time.
6. See number 4 for a description of the system. A site plan is
attached.
7. A statement of Existing For Septic System form is attached.
8. We are willing to pay the required fees at this time.
Based on my evaluation I hereby certify that the existing system is
adequate for the anticipated loading in the foreseeable future. If the number of
employees is increased to greater than 8 then we might need to reevaluate the
system. I have recommended to the operator that he continues to monitor the
system and perform regular maintenance (tank pumping etc.) on a regular basis.

I. GENERAL LOCATION AND DESCRIPTION
The parcel is located at the Southwest corner of U. S. Highway # 85 and
W. C. R. #4. It is in the N. W. '/<, of Section 31, T. 1 N., R. 66 W. of the 6th P.
M. The full legal description is included as Appendix 1 of this report.
There are no major drainage ways in or near to this property. The South Platte
river is approximately %2 mile West of the west line of this property.
The property is located in Weld County and is not adjacent to any named
developments. To the South of the property is a small lake that appears to be the
remains of a gravel mining operation. To the East is Highway It 85, To the West
is a warehouse development and a Ready Mix Concrete Plant. To the North is
more small warehouses and offices for small businesses.
DESCRIPTION OF IMPROVEMENTS
The proposed use for this parcel is as an Auto Salvage Yard. The parcel is
• currently covered with gravel and two buildings. We are not proposing any
additional improvements at this time.
DESCRIPTION OF THE PROPERTY
The property consists of 197,264.65 S. F. (4.53 Acres).
The drainage on the property is generally to the Northwest. We are proposing to
provide a pond, as required, in the vicinity of the Northwest corner of the
property. The water from the pond will be released onto the property to the West
at the allowable rates in accordance with Weld County Regulations. There are no
irrigation facilities located on or adjacent to the property. This parcel is located at
the peak of the drainage for this area. The lake at the south of the property is
approximately 7 feet below this property so there appears to be no groundwater
concerns for the proposed use of this property.
H. DRAINAGE BASINS AND SURBASINS
Major Drainage way, this parcel is located in the South Platte drainage basin.
This parcel falls in Zone C floodplain per FIRM, Flood Insurance Rate Map,map
number 080266 0995 C, map revised date September 28, 1982). An 8 %2"X 11"
• portion of this map showing the property is included in appendix 2 of this report.
•
Local Drainage, this property is configured such that most of the property is
draining to the Northwest and discharging in a sheet manner onto the property to
the West. A small portion of this parcel drains into the U. S. Highway 11 85 on the
Easterly side of the parcel. We have included the total parcel area in our
calculations for detention requirements at the Northwest corner of the parcel.
III. DRAINAGE DESIGN CRITERIA
This drainage report was prepared in accordance with the Urban Drainage and
Flood Control District, Drainage Criteria Manuals as amended by Weld County.
The rational Method was used to determine the peak runoff for both the 10 and
100 year storm recurrence interval. Detention volume requirements were
determined using the equation:
V= KA (SO-1)
Where:V = Required Volume, Acre Feet.
• • K=coefficient, function of the design storm.
A = Drainage Area in Acres.
Detention Release rates are based on analysis of the historical runoff of the 5 year storm
using the formula Q=C IA
IV DRAINAGE FACILITY DESIGN
General Concepts: The design concept for this site is to provide a detention
pond to accommodate the required detention volumes. The storm flow will be
collected into the pond via surface flow. The outfall is controlled to provide
for the allowable release rates. This release will be to the property to the West at
a location mutually agreeable to both owners.
Due to the nature of the proposed use of this property we are proposing to install a
sand trap and an oil separator to assure that the water discharged to the neighbor
will be clean. We are proposing that this installation will replace the need for
Water Quality Control Volume for the detention pond.
•
2.
• SPECIFIC DETAILS:
Drainage swales and Inlet/Pipe System; Runoff is conveyed through the
property as shown on the Grading and Drainage Plan. Swales are formed at
required locations by onsite grading to direct flows to the detention pond.
Detention: Based on developed impervious area of 48% for the developed
property the required detention volumes are 8,623 cu. ft. for the 10 year storm
and 16,755 cu. 11. for the 100 year storm. There is little, if any,offsite flow into
the site so no provision is necessary to accommodate offsite flows.

The plan, as submitted,provides for 31,308 C. F. of detention. There is
also a 1 foot of freeboard included in the final grading elevation.
Allowable Release Rates: Based on the historical 5 year storm event falling on
the historic, undeveloped site with 2% impervious for the entire site.
Q =C IA C =0.16 from Table RO—5
A =4.53 Acres
I = 1.9iph
Q= 0.16 X 1.9 X 4.53 = 1.377 cfs.
We are proposing to control the release rate for this project with the use of a sand
trap and an oil separator. The separator will be sized to release the water from the
pond at the allowable rate for the historic 5 year storm ( 1.38 c. f. s.). As shown
on the plan the pump will be sized to pump the 1.38 c. f. s. (620 G.P. M.)and
• discharge it onto the property to the West. We will meet with the owner to the
4.
• West to determine the exact location and geometry of the discharge facility prior
to preparing the final drainage plan.
The 24 hour 100 year flow into the pond area is 78,931 C. F. This was derived as
follows: 4.8"= 0.40' 0.40 X 4.53 acres X 43,560 C. F. =78,931.
The pump pumping at 1.377 c. f. s. is equal to 118,972 C. F. in 24 hours
calculated as follows:
1.377 X 60 seconds X 60 minutes X 24 hours= 118,972 C. F. This will give us
adequate storage for the 100 year 24 hour storm.
We are providing enough storage in the pond to accommodate the high initial
runoff that will occur in the event of a 100 year storm and still provide 1' of
freeboard.
Erosion Control: Erosion shall be controlled by use of resurfacing for all areas
that are disturbed. Either with gravel or recycled material. The resurfacing
will take place as soon as practical to alleviate any erosion problems.
During construction erosion control Best Management Practices consisting of silt
fences, straw or hay bale barriers shall be utilized on an as needed basis.
• Maintenance Costs: We have reviewed the annual maintenance of the submitted
plan and determined that this design will require no more than cleaning the sand
trap and the separator,as required, and annual checks of the system and possibly
some minor maintenance of the discharge facility. We have estimated that,at to-
days costs,the annual maintenance cost to the owner will be approximately
$ 1,000.00 per year. The oil cleaned from the separator will be disposed of as
required through a recycling company.
V. CONCLUSIONS:
This proposed drainage plan meets the minimum requirements of the Weld
County Amendments to the UDFCD Manuals and the UDFCD Manuals.
Onsite detention and the sand/oil separator system will reduce the developed
runoff rate to allowable rates established by the criteria and state law.
Permanent erosion control measures consist of recycled material or gravel in
disturbed areas.

. Introduction
It has been and my goal to be a positive influence in the world's ecology.
Recycling is the best way to save natural resources and energy. It is our intention to
comply with all Weld County requirements as well as state and local standards in my
vocation of recycling of automotive parts, fuels, metals, and chemicals.
Recycling is my chosen profession,my passion, and is my livelihood. I obtain
complete satisfaction in contributing proactively to the preservation of the earth.
I have always stressed cleanliness, no waste, and environmental concerns. All
people who are employed at Import Line Auto, are proud of our business and of our
• positive influence on the environment.
Recent attention focused on auto recyclers has aroused more questions about my
positive influence and contribution to the planet earth. With more care and
understanding, I shall strive to continue my recycling vocation, make a profit, and
employ citizens in a positive environment.
Sincerely,
Andy Le, President &Founder

A. Facility Description
•
Import Line Auto is located at 987 Hwy 85, Brighton, Colorado, 80603.
The phone number is 303-659-6645. Email address:
importlineauto@yahoo.com. The owner is Andy Chau Le.
The position of the facility in legal terms is as follows: Located at the
southwest corner of U.S. Highway# 85 and W. C. R. #4. It is in the N. W. '/,
of Section 31, T. 1 N., R. 66 W. of the 6th P. M.
The approximate center of Import Line Auto in longitude and latitude is:
Longitude 40 degrees, 1 minute, 18 seconds West and Latitude 104 degrees,
49 minutes, 5 seconds North.
• Import Line Auto compromises of approximately five acres of land. The
facility has an inventory of approximately 200 vehicles and processes about
200 units each year. About one half of the facility is devoted to processed or
staged vehicles and one half is devoted to the storage of reusable parts. 100 of
the total of 200 vehicles are trucks and the rest are cars. The current
warehouse facility keeps parts out of the weather and provides a fence around
the perimeter of the facility. No battery reconditioning is done at this facility.
In order to run the organization effectively, we believe that it must fully
comply with ordinances of Weld County. Therefore, Import Line Auto has
planned to apply in the state of Colorado for a Storm Water Permit.

C. Measures and Controls
• 1. Explanation of Topographical Map
The topographical map is part of Section 20, Township 1 North, Range 66
West of the 6th principle Meridian located in Weld County, Colorado.
2. Comprehensive inspections of all discharge sites and all storm water
related improvements shall be conducted. These inspections shall be
dated and all findings shall be documented on an inspection form. The
inspections shall take place during our quarterly inspections of population
sources.
3. Hazardous Materials and How They are Handled
a. Gasoline and Diesel Fuel
Fuels are pumped out of all vehicles in the shop whrn they are
• staged. Diesel fuel is recycled in our tractors and gasoline is
recycled in our other yard equipment. Demand is greater than
the supply, hence fuel storage is never more than 50 (fifty)
gallons.
b. Used Motor Oil and Transmission Lubricants
Used motor oil and transmission fluid from and engines and
transmissions is drained inside of the shop and deposited in a
waste oil heater tank. The waste oil heater is EPA approved.
Excess fuel is stored in sealed and labeled 55-gallon drums. The
drums are placed in a concrete building with six-inch concrete
beams on each open end.
•
6
c. Antifreeze
• All antifreeze is drained inside of the shop, stores in sealed and
labeled 55 gallon drums, and resold after all the foreign materials
have settled or separated.
d. Batteries
Used batteries are stored inside of the shop and resold.
Discharged batteries are sold to a licensed battery manufacturer.
Discharged batteries are stored in a plastic container with a lid.
e. Brake Fluid
Brake fluid is drained in the shop and deposited in the waste oil
heater, which is capable of burning brake fluid in small amounts.
f. Freon
• All auto air conditioning systems are discharged with an
approved evacuation and cleaning system. Used Freon is sold to
Air Conditioning Certified shops.
g. Parts Washer Solvents and Residues
Our parts washer uses a biodegradable solvent. The filters are
deposited in a landfill.
h. Herbicides
We use approximately two gallons of Roundup per year. We
apply with a hand sprayer to individual thistles and a few other
obnoxious weeds. All the recommendations on the label are
•
7
followed and all handling utensils as well as the Roundup are
• stored inside.
i. Windshield washer fluid is siphoned out of all vehicles and used
in our vehicles.
4. Solutions to Materials Exposed to Storm Water.
a. Over two hundred vehicles are stored on the site. During the
stage process, engines and transmissions are removed and
drained. The stage process also includes the removal of fuel,
antifreeze, batteries,brake fluid, Freon, and wish shield washer
fluid.
b. Reusable auto parts stored outside create harmful pollution
problems. All loose auto parts are stored in racks or on pallets in
• the warehouse facility.
c. Suspension components stored outside may be greasy but storms
have little effect in washing off the grease. All loose suspension
components are stored on racks or on pallets.

5. Spill Prevention and Response Program
All pills, no matter how insignificant are cleaned up immediately. All
bays are swept daily and heavily used concrete slabs are swept at least once a
week.
Vehicles are kept in good working order. Faulty seals and hoses are
repaired immediately. Vehicles are maintained inside the shop to further
reduce possible storm water contamination.
We have a permanent home for shovels near the shop. Fifty-five
gallon drums as well as five gallon buckets are readily accessible. 3M oil
• absorbent pads are stored inside the shop. Professional clean-up personnel use
this same material in major oil spills. The used pads are deposited in a sealed
drum to be picked for recycling.
In case of a spill which needs professional services or advice we have chosen:
Safety Kleen

Colorado Department of Health:
In the case of a reportable spill, the Colorado Dept. of Health number to call
is: 303-692-2000.
Local Fire Department:
In case of a hazardous spill the local fire departments hazardous material team
may be helpful.

6. Employee Training
• All new employees are given a full written job description when
they are hired. The Pollution Prevention Plan has become an integral part
of our policy and is addressed to them on their first day of employment at
Import Line Auto.
An employee who is familiar with all company policies trains new
employees. This training lasts from one to two weeks. The new employee
works one on one with a fully trained employee. All members of the
pollution prevention team are full time employees and keep a watchful eye
on new employees, giving environmental housekeeping pointers to new as
well as established personnel.
Frequent company meetings held allow our pollution prevention
• team to give helpful hints, and "pats on the back," when all employees are
present. We have two or three meeting a year.
•
11
7. Storm Water Controls
• During all storm events, 3M oil absorbent pads are placed in the
ditch near the southeast corner of the shop. This concrete ditch drains the
work area on the south side of the shop. The pads are placed in the ditch
in such way that they float on the surface of the escaping water. A wire
grate is placed over them so that they don't blow away. These pads are an
effective method of stripping off the oil and grease that is floating on the
surface of the wastewater. The pads are frequently replaced, usually after
every storm event.
Near the southeast corner of the shop, two/one thousand gallon holding
tanks are located conveniently.
