Page 1 Berven Industries LLC Weld Co Dust Abatement Plan Objective : The purpose of this dust abatement plan is to reduce to as much extent as possible the amount of airborne dust particles being generated at this project site during and after construction activities. Construction : During the construction phase of the project, Berven Industries LLC and its contractors will utilize water trucks to maintain dust suppression . Additionally, any haul trucks leaving the site will cover their loads prior to departure. The Storm Water Management Plan will be followed to mitigate soil erosion during the construction phase. Following Construction : At the conclusion of facility construction, all vehicle roads, vehicle parking and truck loading areas will be converted to hard surface asphalt or concrete pavement. This will provide sufficient dust control for all vehicle activities. The remainder of the disturbed construction and building site will be stabilized using native seed, shrubs, and trees. Grasses will not be allowed to grow over 12" high . Ongoing daily operational activities are not expected to create airborne dust particles; however, local activities will be continually monitored . If dust generation becomes a problem, additional measures will be taken to eliminate all sources of airborne dust. 441( 61,4 DEPARTMENT OF PLANNING SERVICES I1555 N 17th AVE GREELEY, CO 80631 C� PHONE: (970) 353-6100, Ext. 3540 COLORADO FAX: (970) 304-6498 AUTHORIZATION FORM 11/4--t \0._.0 represent for the property (Agent/Applicant) (Owner) located at No Add-aar, f - cam( ti " Gtr 1433 - Z7 - o -o0 -068 • LEGAL DESCRIPTION: SEC 7 TWN 1 !•1 RNG 65 Li SUBDIVISION NAME: 'VA LOT BLK I can be contacted at the following phone#'s: Home 9-17 - i3 ( - (a (4.2- Work 3 03 - `F5Q- 2- -0o Fax # 303 - 45. 7- LS-5-9, The property owner can be contacted at the following phone #'s Home 303 - 4OD - 19i0 Work 3 - 933 4-Ug9 Fax # 303 75b - S5 /1 Correspondence mailed to (only one): [I Agent/Applicant ❑ Property Owner DATE t /I 07/to OWNER'S SIGNATURE Y p axAmA.4- Chris Gathman From: Jeremy Berven <jeremy@newdealdeicing.com> Sent: Tuesday, April 12, 2016 5:14 PM To: Chris Gathman Cc: laura@newdealdeicing.com Subject: USR16-0008 Good Afternoon Chris, It was nice speaking with you today.

Powers Brown Architecture Name Attest: (Name of Responsible Party) Notary Public Authorized Signature II. GENERAL LOCATION AND DESCRIPTION A. Location 1 . The site for New Deal Deicing Facility is located in the Southeast 1/4 of the Southeast 'A of Section 27, Township 1 North, Range 65 West of the 6th P.M., Weld County, state of Colorado. 2. The site is bounded on the north and west by private property, on the south by County Road 4, and to the east by County Road 45. 3. There are no major channels, lakes, streams, irrigation and other water facilities within and adjacent to the proposed project site. 4. The site location is shown on the vicinity map in Appendix A. B. Description of Property 1 . The property is 34.61 acres. 2. The ground cover at the site consists of native grass, vegetation, and bare ground. The existing terrain is undeveloped agricultural land that drains south toward County Road 4. Soils as indicated in the NRCS soil survey are primarily vona loamy sand, with 0 to 5 percent slopes. These soils are in hydrologic soils group A. 3 . There are no major open channels on this property. 4. Proposed improvements include the construction of a potable water well, a full spectrum detention pond, and an access road from County Road 4 to the south side of the site. The first phase of construction is scheduled for fall 2016. The property is the future location of a new industrial deicing manufacturing facility. 5. There are no irrigation facilities within 200ft. of the property boundary that will be affected or impacted by the site drainage. 6. Geotechnical report is not yet complete and groundwater conditions are unknown. III. DRAINAGE BASINS AND SUB-BASINS A. Major Basin Description 1 . The site is located outside of any named major drainage basins. There are no previous drainage master plans or reports for this area. Historically, the surface drains to the south, across County Road 4 to an adjacent property through an existing X" culvert. 2. The property is located within zone C, areas of minimal flood outside the 100-yr floodplain, as indicated in Flood Insurance Rate Map No. 080266 1025C (see Appendix A). There are no major drainageways within or adjacent to the project boundary that will affect the development of the site. B. Minor Basin Description 1 . There three existing minor basins studied as part of this drainage report (Sub-basin A, Future, and OS- 1 ). Sub-basin A is the drainage area sub- basin bounded by the project property line and sub-basin Future is the drainage basin that is delineated for the study of the future deicing facility. Sub-basin OS-1 delineates offsite drainage area from adjacent properties of site. The three basins are described as follows: a) Sub-basin OS- 1 — The 33.93 acre basin currently consists of native grasses and agriculture land uses. The offsite runoff enters the site from the North and the West, entering sub-basin A and discharging through the same culvert on the south side of the site. The sub- basin has rational coefficients of 0.02 and 0. 17 for the 10-year and 100-year runoff events respectively. The historic runoff from Basin OS- 1 will generate a flow of Q i o = 2. 1 cfs and Q100 oo = 34.2 cfs. b) Sub-basin A — The 33.43 acre drainage basin currently consists of native grasses and undeveloped agricultural land. The rainwater runoff enters a culvert and crosses the County Road 4. The sub- basin has rational coefficients of 0.02 and 0. 17 for the 10-year and 100-year runoff events respectively. The historic runoff will generate a flow of Qio = 2.0 cfs and Qioo = 31 .7 cfs. c) Sub-basin Future — The 2.70 acre drainage basin currently consists of native grasses and undeveloped agricultural land. The sub-basin has rational coefficients of 0.02 and 0. 17 for the 10-year and 100- year runoff events respectively. The historic runoff will generate a flow of Qio = 2.0 cfs and Qioo = 31 .7 cfs. 2. All of the land within this 70.07-acre drainage study was analyzed for the phase 1 build out of the deicing facility. The future developed flows will be conveyed through the site and were not included in this analysis. IV. DRAINAGE DESIGN CRITERIA A. Development Criteria References and Constraints 1 . There are no previous drainage studies for the New Deal Deicing property. 2. There are no unusual on-site constraints such as streets, utilities, rapid transit or existing structures. B. Hydrologic Criteria 1 . The design rainfall for this project was determined using the NOAA ATLAS precipitation frequency estimates. 2. The design storm recurrence intervals are for a 10 year and a 100 year. The 10 year event has a one hour point rainfall depth of 1 .38 inches and the 100 year event has a one hour point rainfall depth of 2.60 inches. 3. The rational formula was used to calculate all site runoff. The rational formula was used in this report to evaluate peak runoff due to relative size of the basins (i.e., less than 130 acres) 4. The modified FAA method was used to determine the 100 year storm pond detention volume of 23,871 cubic feet to discharge at the historic 10 — year rate. 5. This project will be designed for a full-spectrum detention. Most of the stormwater will be directed around the developed impervious areas of the site to outlet through the existing culvert crossing County Road 4 to the South. The remaining flow will be directed into a full spectrum detention pond and the pond discharge for a 100 year —event will be controlled to the historic 10 year — event of 2. 1 cfs. C. Hydraulic Criteria 1 . Pipe and channel capacity was calculated using Manning's formula for the design. Hydraulic modeling is presented in this report using a conventional evaluation of system hydraulics using Bernoulli's equation for junction head loss and Manning's equation to evaluation friction slope losses through the piping system. 2. The conceptual detention outlet will be a two stage EURV outlet structure that will include water quality capture volume. V. DRAINAGE FACILITY DESIGN A. General Concept The general drainage design concept for this site is to maintain the historic drainage patterns for the proposed development and to accommodate future expansion of the deicing facility. The first phase of the project includes the access road and utility installation. A future phase will be the expansion of the deicing facility on the East and the West sides of the building. Drainage calculations take into account all future expansions. The Design Criteria outlined by Weld County as well as Urban Drainage and Flood Control District Criteria Manual was utilized for guidance. All proposed drainage conveyance elements is sized to handle developed runoff in the first phase. When and if there the facility expands, the storm pipe will need to be designed to convey the developed storm flows. B. Specific Details 1 . There four minor basins created for the developed drainage report (Sub- basin OS- 1 , A, B, and C). Sub-basin OS- 1 delineates offsite drainage area from adjacent properties of site. Sub-basins A and B are the undeveloped drainage area sub-basins bounded by the project property line. Sub-basin C is the developed portion of the site. The four basins are described as follows: a) Sub-basin OS-1 — The 33.93 acre basin has rational coefficients of 0.02 and 0. 17 for the 10-year and 100-year runoff events respectively and will generate a flow of Q i 0 = 2. 1 cfs and Q i oo = 34.2 cfs. b) Sub-basin A — The 26.30 acre basin has rational coefficients of 0.02 and 0. 17 for the 10-year and 100-year runoff events respectively and will generate a flow of Qio o = 2.0 cfs and Q i oo = 33.3 cfs. c) Sub-Basin B — The 7. 14 acre basin has rational coefficients of 0.02 and 0. 17 for the 10-year and 100-year runoff events respectively and will generate a flow of Q10 = 0.4 cfs and Q100 = 7.2 cfs. d) Basin C — The 2. 10 acre developed basin that makes up the deicing facility's building, roads, and parking. This basin includes a full spectrum detention pond and will discharge at the historic 10 year rate of Q100 = 0.2 cfs for a 100 year event. VI . CONCLUSIONS A. Compliance with Standards 1 . The drainage facilities for civil infrastructure for the New Deal Deicing Facility have been designed in accordance with the Urban Drainage and Flood Control District Criteria Manual and the Weld County Code. B. Drainage Concept 1 . The drainage design will not have any adverse impacts to any downstream drainage facilities. Runoff will be routed to the proposed full spectrum detention pond to control a 100 year hour event to historical 10 year event rates. VII. REFERENCES 1 .

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission . Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential , soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material . These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

estimates in this table are based on frequency analysis of partial duration series (PDS). Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
