SHAT OPEE TO: Mayor and City Council FROM: Kyle Sobota, Senior Planner DATE: 04/07/2015 SUBJECT: Appeal of Board decision regarding approval of Conditional Use Permit for Northwest Asphalt Caselog #15-021. (B) Action Sought Approve Resolution No. 7570, which upholds the Board's decision to approve Conditional Use Permit Resolution No. PC15-010. Site Address: 1451 Stagecoach Road Applicant: Northwest Asphalt Property Owner: Pfeiffer Properties LLP Current Zoning: I-1, Light Industry Land Use Guiding: Industrial Site Acreage: 10.45 acres Adjacent Land Use and Zoning: North: NuStar/Prairie Line (I-1) South: Multi-tenant Industrial building (I-1) East: Multi-tenant Industrial building (I-1) West: Stormwater Detention Pond (B-1) and NuStar/ Prairie Line (I-1) On March 5, 2015, the Board of Adjustment and appeals approved a Conditional Use Permit Amendment request for Northwest Asphalt by Resolution No. PC15-010. The amendment request involved increasing the amount of time Northwest Asphalt is permitted to crush concrete and asphalt material in a calendar year from 20 days to 60 days. No other conditions were requested to be amended. As stated, the Board approved the applicant's request with the addition of a condition regarding a water truck being on site during crushing to mitigate dust anywhere it is generated. A copy of the report and resolution presented to the Board is attached. The revised resolution from the Board's direction is also attached. On March 16, 2015, Chris Anderson and Robert Kimmel (appellants), who own property adjacent to Northwest Asphalt on Maras Street, filed an appeal application appealing the Board's approval of the amendment. The reason for appeal given by appellants is that they believe the crushing operation has damaged their building, reduced their property value, and reduced the enjoyment of their property. The letter provided by Mr. Anderson and Mr. Kimmel is attached for the Council's review. The appellant also submitted photographs of their building and Northwest Asphalt's building, as well as other adjacent buildings to show the construction types in the area. The photographs are attached. The appellants also contacted an engineer to review the condition of their building. An Engineer's report on the inspection of the appellant's building is attached. The Engineer's report states that "upon our initial investigation, the crushing operation would not be suspect as the prime factor for the observed stress, but does appear to be advancing the stages of the structural issues." The report also states that additional testing may be completed during the crushing operation. The appellant submitted photos of Northwest Asphalt's building and in conversations with planning staff has stated that they believe that the crushing operation has damaged Northwest's building as well. Northwest Asphalt provided an Engineer's Report on the condition of their own building, which the Engineer found that the damage to their building is most likely attributed to water damage from freeze-thaw cycles and the pervious concrete block used to construct the building. The Engineer's Report prepared for the Northwest Asphalt building is also attached. The appellant has also provided information by e-mail (attached) to planning staff regarding silica air emission regulations, which is governed by MPCA regulations. Intex Corporation,Northwest Asphalt's crushing contractor, has an emission permit from MPCA. Intex Corporation provided test information from tests completed in 2014 on Northwest Asphalt's site, which show that they meet MPCA requirements of at least 1.5% moisture content for crushed material, testing is required by their MPCA permit (attached). Intex Corporation also provided test results on two of their equipment operators regarding the employee's exposure to silica. The employee testing levels were found to be in compliance with exposure limits. The test results for moisture content in the crushed material and the employee exposure are attached for review. The City Council is charged with determining if the Board of Adjustment and Appeals made an error in approving the amendment request. From information provided by the appellants and Northwest Asphalt, staff believes that Board's findings meet the criteria for granting the amendment, allowing Northwest Asphalt to crush material for 60 days / calendar year. Staff has prepared Resolution No. 7570, with findings and conclusions for the City Council's review. If the City Council grants the appeal, Northwest Asphalt would revert to their approved Conditional Use Permit, Resolution PC07-007, which allows crushing for 20 days per calendar year.

SFiz-kKOPEE TO: Shakopee Board of Adjustments and Appeals FROM: Kyle Sobota,Senior Planner DATE: 03/05/2015 SUBJECT:PUBLIC HEARING-Conditional Use Permit Amendment for Exterior Storage of Rock and Stone Products at 1451 Stagecoach Road. Caselog#15-010. Caselog No 15-010 Discussion Site Address: 1451 Stagecoach Road Applicant:Northwest Asphalt Property Owner: Pfeiffer Properties LLP Current Zoning: I-1,Light Industry F Land Use Guiding:Industrial Site Acreage: 10.45 acres Adjacent Land Use and Zoning: North:NuStar/Prairie Line(I-1) South:Multi-tenant Industrial building(I-1) East:Multi-tenant Industrial building(I-1) West:Stormwater Detention Pond(B-1)and NuStar/Prairie Line(I-1) Northwest Asphalt has made an application to amend their existing Conditional Use Permit for exterior storage of rock and stone products.This specific request relates to the amount of time that crushing of concrete and asphalt is permitted on the site.Currently,crushing of concrete and asphalt is permitted for 4-weeks annually.Northwest Asphalt is requesting a timeframe extension to 12-weeks annually.An extension of the approved crushing duration is the only requested modification to the conditions of approval. In 1988,Northwest Asphalt received a Conditional Use Permit for exterior storage of rock and stone products.As part of the request, crushing of concrete and asphalt was approved on the northern portion of the site for 4 weeks annually on weekdays from 7:00 am to 7:00 pm.In 2007,a Conditional Use Permit amendment was approved by the Board that that superseded the Conditional Use Permit from 1988 and increased the size of the permitted area for storage of crushed material to include the southern portion of the property,as well as an increase the permitted height of crushed material from 20'to 30'for a period of 48 hours during crushing.The permitted height of broken [' material piles is 20'. In 2006,staff received complaints about noise and dust generated on the site during crushing operations,which resulted in the applicant seeking an amendment to their Conditional Use Permit. Since 2007,staff has worked with the applicant to control the amount of dust that leaves the site by increased control of the crushed material conveyor height in relation to the crushed material pile,increased water usage,and not crushing on windy days. Some of the conditions of the 2007 amendment included the installation of a 10'tall berm on the north,west,and eastern areas of the site.91 Evergreen trees were planted on the berm to screen the material piles and since 2007 only one of the trees has not survived.From staffs observations the berm has greatly decreased off-site noise levels and the trees have grown significantly'fcantl since 2007 to screen the piles of material. There is also an existing condition that the applicant must notify the City and adjacent property owners at least two business days prior to crushing. p.. During crushing in the past few years staff has not received any complaints from adjacent property owners other than one complaint regarding an instance of equipment being tested prior to 7:00 a.m.. Current photographs of the site showing the berms and broken material pile are attached.There is no crushed/finished material on the site currently. Other Considerations: Staff has received comments from an adjacent property owner that is not in favor of this amendment request.The comments have been provided to the applicant and are attached for the Board's review and consideration.From staffs observations from being on site the during crushing activities,staff has not observed complaints similar to what Mr.Kimmel describes.Staff has also not received similar complaints from adjacent property owners that are in multi-tenant buildings.Any damage found that is found to be caused by the applicant's activities would be a civil issue between the applicant and Mr.Kimmel. Staff recommends that the Board approve the request based on the establishment of the berm,maturing trees on the berm,and efforts of the applicant to mitigate dust generation on the site.Staff has included a draft resolution of approval of the applicant's request for the Board to consider.The applicable conditions from the 2007 Conditional Use Permit have been carried forward in the attached draft Resolution No.PC15-010.The resolution from the amendment in 2007 is attached for the Board's reference. Staff Recommendation Staff recommends approval of the Conditional Use Permit amendment,subject to the conditions in the draft resolution. Action Requested Offer a motion to approve Resolution No.PC 15-010,and move its adoption.

A HISTORY OF THIS CUP The original CUP for crushing for this property, was adopted July 7, 1988, by the I. owners of the property and Northwest Asphalt Inc,. at that time. It held the same time frame parameters as the current CUP and the same criteria with the exception of no tree plantings were required on the berming in the original permit, and the height limit for both the chunk and recycled finished product pile was 20 feet. In the winter of 1998, ownership of the business and property at this location, was transitioned to Mike Pfeiffer and Debra Hendrickson, due to the failing health of their father, Donald Pfeiffer,who by that time was the sole owner of the business (Northwest Asphalt Inc. & Pfeiffer Properties LLP) and property. We continued operations of the business and occasional crushing based on what our father had done and told us. We admittedly, never sought out direction from the city or searched for the CUP permit to review it. Then in 2007, with the company having grown significantly, along with increases in the use and encouragement of recycled materials, Mike and Debra spoke with the city/board in hopes of increasing the crushing allowances. At that time it was brought to their attention that the existing CUP (CUP resolution no. 530 from 1988) was not being followed to the letter. Because of this, no extension of time was granted, however;the finished product pile height was increased from 20 feet,to 30 feet to allow for more crushed volume. In addition to this, repair and modifications to the berming was added with 90 evergreen variety trees to be planted and maintained, prior to any further crushing. Inspections followed, with verification of all criteria being met.This information was then provided to the board at the October 18, 2007 meeting. Northwest Asphalt Inc. has been functioning and adhering to that permit ever since. • • WHAT IS CRUSHING ALL ABOUT Over the past 20-30 years,the technology and use of various materials for recycling, has been encouraged and promoted in our industry and in our lives in general, in numerous applications. What we are doing under this CUP, and what numerous other aggregate suppliers are doing also, it converting or "recycling" asphalt and concrete chucks, coming from demolished roads, parking lots, • sidewalks, retaining walls, etc., and crushing them in specific ratios, to provide an end result product,that is an aggregate material similar in use as crushed limestone,which previously and is currently still used for construction of roads, sidewalks, back fill and drainage in a wide variety of erosion control and landscaping projects, etc.The use of this recycled product, not only makes good sense from an environmental and natural resources preservation stand point, but is also more cost efficient than use of natural stone materials such as crushed limestone, because these materials are increasing less available within our metropolitan area. There are already considerable volumes of materials being shipped and trucked into our area because of a diminished local supply. This Ii diminishing supply will of course eventually be gone completely. Use of recycled material for projects means decrease in costs to build the Y p 1 projects, such as street and road projects, as they are awarded by low bid. This directly benefits the municipalities, and in turn the tax payers. WHY DO WE NEED ADDITIONAL TIME FOR CRUSHING Over the past 7 years, we have continued to crush almost annually, and have adhered to all criteria listed on the CUP (PC07-007). We have developed methods • to reduce and eliminate any dust issues, by watering the area frequently, running a hose onto the crusher conveyors and keeping the height of the end of the conveyor always at the lowest possible point, preventing dust from taking flight. We have had just one noise complaint, which was due to an operator from the crushing company we hire to do the work, starting equipment prior to the 7 am start per CUP. This was corrected and has not happened since. The berming and all its plantings have been maintained and have grown significantly. So why the added time request? Over the past seven years, not only has our company continued to grow, but the acceptance and preferred use of recycled product has also grown significantly. For several years in a row now, we have both run out of room for accepting the asphalt and concrete chucks, and run out of time to completely finish crushing those chunks, due to the 4 week(20 day) limit. Both of these problems are the result of the limited time to crush.This past summer, due to scheduling problems with the crushing company, they crushed for us for 2 weeks,then left for several weeks and then returned to crush for the remaining 2 weeks. During the time they were gone, we ran out of our crushed pile. On their return, they ran out of time to complete the crushing of the chunk pile and we were once again unable to fully utilize the chunks we had acquired. By the end of the season we had again run out of recycled product, creating the need to use more expensive limestone products, and thus affecting cost to the projects and consumers. The additional time we are requesting, would still need to adhere to ALL of the other criteria of the CUP. It would simply allow for extended time, or several periods of crushing, which would more consistently provide continued availability of recycled product for all projects. Any concerns that this could turn into an on- going crushing operation, I would refer you to the layout plan of our yard. We lack the space to handle continuous crushing or stock piling of materials. This alone is a defining and limiting factor to our operations. The fact that over the past 7 years, we have fully complied with all CUP criteria with essentially no complaints,we feel testifies to our dedication to remain in compliance with all regulations and the well being of our neighborhood,and directed use of this zone . We respectfully request that you allow this additional time to our CUP. Thank you Mike Pfeiffer& Debra Hendrickson : ■ 1/14/2015 Northwest-Google Maps 4 Northwest,1451 Stagecoach Road (952)445-1003 a • 1 review . ,.,_;.- r - _ - lit:44.-. -,..._. , ., H y .I I IE t __ Ti11�l 1 , ,, �-IE .h j t J- P -�,.. ,; 7,_4,r n -- r21 ��yyc r .1 t at V 6 ' -e— k 1 4 Northwea, p mt ' �;. i •. fr '4.

During this time we have been subjected to the Crushing Operation for one month a year.While the crusher is operating,it shakes the ground,and our building to the point where the light fixtures are constantly swaying,the suspended furnace is constantly rattling.When the bulldozer is on top of the pile(frequently)the constant back and forth is so loud,that we cannot have a conversation,or talk on the phone without shutting all the doors. Given the fact that the crusher vibrates our block wall building,we feel that it is causing damage.We are seeing cracks on the building walls,in the concrete,and problems with the roof that is likely being caused by the constant vibration. I have spoken with the other owners in the area,and we don't understand why a crushing operation is so close to other commercial buildings.Whenever I see other crushing operations,it is out in a field away from everything.We believe it is time for Northwest Asphalt to move their crushing to a more appropriate Off Site location. From the information I have received,it appears that they want to expand Crushing from One month,to Three months per year.This is completely unacceptable. Who is going to pay for the damage that is caused,and/or business lost because the neighboring businesses will become completely uninhabitable and worthless? We will be also coming to this meeting Robert Kimmel • • I RESOLUTION NO.PC07-007 A RESOLUTION OF'1HE CITY OF SHAKOPEE • APPROVING A CONDITIONAL USE PERMIT FOR EXTERIOR STORAGE ROCK AND STONE PRODUCTS AT 1451 STAGECOACH ROAD WHEREAS,the City of Shakopee received an application,from Michael Pfeiffer, representing Northwest Asphalt and Pfeiffer Properties LLP,property owner,for a Conditional Use Permit to allow exterior storage;and • � I WHEREAS,the property for which the application was made is legally described as follows: Lot 2, Block 1, and the East 419.76 feet of Lot 1, Block 1, all in Patch 1st Addition, Scott County, MN.

I am writing to you concerning the Public hearing on March 5(Northwest Asphalt extended crushing)I know my neighbor Robert Kimmel has contacted you about this matter and I just want to say that I completely agree with everything he has mentioned especially about the continuing damage to our building. I would also like to add that being that I have an body shop,the dust and dirt that is created from the 20 days of crushing is quite extensive,to the point of having to close all the doors in the shop just to get a half way clean paint job in the booth and when the vehicles are done and waiting to be picked up,it's a constant battle to keep them clean until they are. And that's in the front of the shop.

Michael Leek, Community Development Director PREPARED BY: City of Shakopee 129 South Holmes Street Shakopee,MN 55379 PC15-010 We would like to Appeal: Criteria#1 The use will not be injurious to the use and enjoyment of other property in the immediate vicinity for the purposes already permitted,nor substantially diminish and impair property values within the immediate vicinity. There has not been any testing during the crushing operation to see the effects of surrounding buildings,and there has been no one from the city or planning commission checking on how the crushing is affecting surrounding properties. We had an inspector come out from ITCO(see attached letter)lend an opinion for the damage to the buildings(attached letter),but cannot get a ground measurement without the crushing equipment operating. So,we would like to postpone the Boards decision until proper testing can take place. We would like to have Braun Intertec (see attached) Do the testing when the crusher is running. Also Item 12 on the resolution states that all equipment on site shall be in compliance with MPCA noise standards.We would like to have testing done on this when the Bulldozers are running. We have included several photo's of damage to the building. • 5 � �a € ;,» ,IJ # i Y ' , .

Supporting documentation conveyed to us during the inspection included a copy of: City of Shakopee Conditional use permit, Resolution No. PC15-010. Stress within the buildings was observed primarily as cracks within the perimeter CMU walls. The most evident was the south wall of the (1444) building where a crack radiated down from the top of wall adjacent to a bearing beam wall pocket&the upper bond beam. The crack stepped down through mortar joints & masonry block approximately 4 courses. The stress was also visible at the out-side wall, as a differential shift on the vertical axis approaching 1/2". Also, some embed bolts securing the south wall angle plate for roof panel attachment, are loose & backing out from the blocks. Stress within the west wall of the adjacent north building, was observed as a vertical stepped crack adjacent to a pilaster, or series of jam blocks placed for an optional future 12' door opening. We were also advised that during operation of the crushing facility, there is rattling & movement of the elements associated with overhead radiant heating system,for which some repairs have been made. It is our understanding that the crushing operation also requires the use of large earth moving equipment in the form of a "D9 Cat Dozer". This steel cleated track equipment can often weigh in the range of 107,550 pounds & produce a ground borne vibration level of(94-95 Vdb) as measured 50 feet from the source. As a reference, blasting from construction projects measured @ the same distance can produce a velocity level of 100 Vdb. Relative to site geology, soil & subsurface conditions can have a strong influence on the levels of ground-borne vibration. Among the most important factors are the stiffness & internal damping of the soil, ground water levels, and the depth to bedrock. Based upon our initial investigation,the neighboring crushing operation would not be suspect as the prime factor for the observed stress, but does appear to be advancing the stages of the structural issues. Future site investigation may include a subsurface geotechnical investigation and seismic monitoring during crushing operations.

This is known to cause health problems, and a respiratory disease called silicosis.

The building condition assessment was prepared to get a professional opinion to the cause for cracking in our concrete block in the exterior of the shop, which had been present for many years. We have had concrete contractors look at the building in the past and give their opinion, but wanted to make sure a structural engineer held the same opinion, which they do. Recently we completed a major remodel to the interior of our building, and now plan to fix up and re-paint the exterior, so it was time to assess the issues. As you will see by the report, it is felt that this cracking is due to water intrusion over the years. This is very repairable by a concrete contractor who does this type of work, which we plan to do this summer. We had specifically asked the engineer to factor in her assessment, if vibration from a crusher working in our yard could be a factor to the block issue. Her determination as you will see, was that it is weather related. The 2014 gradation Report, is included here to show not only proof of the extent we water the crushing/conveyor, but also to show the extend of silica exposure due to crushing, which is evidenced by 2 employee silica testing reports (attached at the end of the crushing gradations) . The employees are workers stationed on the crusher/conveyor, the other a loader operator dumping the chunks into the crusher. As you can see, the results are well below acceptable standards (with 1 being the threshold standard, one employee at .119, the other at .628) AN EQUAL OPPORTUNITY EMPLOYER Regarding watering during crushing, and the moisture content: The MPCA minimum acceptable level of moisture content is 1.5%. As you can see from the reports, we far exceed that with averages of 3.9% and4.4% . Watering is done not only to decrease dust, but also reduce any exposure to silica (a substance in concrete) which could be in the dust. Therefore; we are confident with the extent of watering we do during crushing, is adequate to handle any potential hazards of the dust exposure. If you have any questions regarding any of this, please let us know. Thank you Mike Pfeiffer Debby Hendrickson AMERICAN CONSULTANTS •ENVIRONMENTAL ENGINEERING •GEOTECHNICAL TESTING,INC.

SHAKOPEE,MINNESOTA SHAKOPEE,MN 55379 ATTN: DEBRA HENDRICKSON AET PROJECT NO: 05-06417 DATE:MARCH 25,2015 INTRODUCTION This report presents the results of our condition assessment work performed on the exterior concrete masonry (CMU) of the Northwest Asphalt shop and office building in Shakopee, MN. - The scope of our work was limited to: 1. Performing observations to document the cracks and distress in the CMU walls. 2. Preparing a written report of our findings, including our opinion on the cause of the distress. Our work was authorized by Debra Hendrickson of Northwest Asphalt on March 23,2015. CONCLUSIONS Based on the results of our service and experience on similar projects, we offer the following opinions: 1. The CMU blocks appear to be lightweight pervious concrete. The grouted cells appear to have trapped water in the cores. The trapped water will freeze and expand causing hairline cracking on the face shell of the CMU blocks. This type of cracking was observed in multiple locations of the building exterior. 2. The most severe cracks were located at the west corners of the shop area (reference note 1 and 2 in the results section). These cracks were initiated by the water and made worse from the stress of the structural members connecting at that point. 3. No expansion joints were observed in the CMU walls and vertical cracks from thermal stresses have occurred at regular intervals along the length of the wall. 550 Cleveland Avenue North I Saint Paul,MN 55114 Phone(651)659-9001 I(800)972-6364 I Fax(651)659-1379 l www.amengtest.com I AA/EEO AET Project No. 05-06417 -Page 2 of 3 BACKGROUND INFORMATION The following information was furnished for our work by Debra Hendrickson of Northwest Asphalt on March 23,2015. 1. The building was built in the late 1970's. The building is approximately 140'x 180' with a height of 20'. 2. Multiple times a year, Northwest Asphalt brings a mobile crusher on the property to create recycled asphalt material. This piece of equipment usually is located in the parking lot on the North East portion of the property, approximately 50 yards from the closest corner of their building. 3. The building is made up of structural steel members, CMU walls (16 x 8 for the infills and 16 x 12 for the structural wall) and metal panels. The shop area is supported by structural steel beams and columns on the North, East and South walls. A CMU wall spans the entire west elevation,with each end being exterior and the lower middle portion being interior at the office area. AET relied on this information in performing our assessment and developing our opinions. Unless we are notified otherwise,we believe this information to be true and correct. PROCEDURES The condition assessment was performed on the exterior CMU walls to document the location, extent and severity of significant visual distress in the requested locations. Observations were made to document cracking, bowing, spalling, scaling, localized buckling, failed connections, distortion, obvious movement and evidence of alterations to the structure. Photographs were taken during our work to document conditions present. RESULTS Our condition assessment was performed on March 23, 2015. The results are as follows. Reference the attached sketch and photos: 1. Cracks along the entire length of the corner with it being more prevalent at the top. The crack is visible from the interior. Hairline cracking in face shell consistent with trapped water being present in the block. (Photographs 1-3) 2. Cracks along the entire length of the corner including hairline cracking in face shell consistent with trapped water being present in the block. (Photographs(4-6) 3. Water staining along the face shell and joints. Crack expansion at joints and typical settlement cracks observed. (Photographs 7-8) 4. A chipped portion of the block at a side access door. Large air voids observed in the exposed surface. (Photograph 9) AET Project No.05-06417 -Page 3 of 3 5. Hairline cracking consistent with water trapped in the block and expanding at low temperatures. This is observed in multiple locations throughout the entire exterior of the building. (Photograph 10) 6. Vertical crack in the CMU infill between two garage door bays. 7. Vertical crack observed in the interior at the midspan of the CMU wall. LIMITATIONS Our work was limited to documenting the condition of the exterior wall and should not be construed as review of the overall design, construction and code compliance of the building. It should be noted that a reasonable effort was made to observe the exterior wall in the requested locations. Since our work scope was limited to visual observations, some hidden conditions may not have been discovered during our assessment. Further, should conditions differing from those documented by AET at the time of our work be found in the future, AET reserves the right to review our conclusions and recommendations and modify them accordingly. STANDARD OF CARE The work performed by American Engineering Testing, Inc. has been conducted in a manner consistent with that level of skill and care ordinarily exercised by other members of the profession currently practicing in this area under similar time and budgetary constraints.

These pages are part of a long report we received from the independent testing company. I can send the full report if you would like. As far as measures to control the dust emitted,we apply water to the material. Our MPCA permit require that we have a minimum of 1.5%moisture content and that we monitor the moisture content throughout production. So every time we run a gradation,we also calculate the moisture content. I attached the gradations from your site last year. As you can see,we never dipped below that minimum threshold and averaged 3.9%and 4.4%moisture content respectively. If you would like us to attend the meeting on April 7th in case any questions come up,we would be more than happy to do so.

Using the data listed above the following values have been determined: PEL Exposure Severity SAE* LCL** UCL*** (mg/m3) (mg/m3) (Exposure/PEL) 0.769 0.483 0.628 0.3 0.328 0.928 * Sampling and Analytical Error ** Lower Control Limit *** Upper Control Limit I I Based on the severity calculation the marked action is recommended. [X] A severity less than or equal to 1 means that you are under the Permissible Exposure Limit (PEL). If the sampling and analytical error upper control limit is greater than 0.5, it is recommended that you examine your workplace for possible 1/2 6/2/2014 ' ''actions you may be able to take to further lower your exposre. [ ] A severity less than or equal to 1 means that you are under the Permissible °!'xposure Limit (PEL). However, the sampling and analytical error upper control limit indicates that you may be above the PEL. You should continue to monitor your exposure to confirm that you are below the PEL, and it is recommended that you take appropriate actions to reduce your exposure. [ ] A severity greater than 1 means that you are over the Permissible Exposure Limit (PEL). However, the sampling and analytical error lower control limit indicates that you may be below the PEL.

FACILITY DESCRIPTION: The Intex Corporation- Portable facility processes crushed stone and sand for use in various construction applications.The facility processes include crushing,screening,and transport of crushed stone and sand. Diesel generators are used to power the equipment. Emissions are primarily dust from the processing and hauling of the material,and combustion byproducts from the generators. Pollution control measures include monitoring of material moisture content and the addition of water sprays to reduce the occurrence of fugitive dust. AMENDMENT DESCRIPTION: This permitting action is a major amendment to allow additional equipment and increased production capacity,to revise permit language to establish procedures for equipment replacement, and to eliminate the requirement for computer dispersion modeling through fulfillment of the modeling requirement. This permitting action defines the term Crushing Spread,which is the group of units that are used for nonmetallic mineral processing(and subject to 40 CFR pt. 60,subp. 000).The permit further limits the types and maximum quantities of each type of emission unit contained within a Crushing Spread, based on the results of the modeling. This permitting action also corrects the annual throughput limits for the facility and increases the number of Crushing Spreads allowed;the original permit incorrectly limited the throughput and hours of operation of the facility by not having those limits apply separately to each spread.

In previous discussion with the MPCA,it was decided that the fenceline was to be located no more than 3.05 meters(10 feet)from the process equipment. In our protocol,the size of the site was incorrectly assumed to equal 64.3 meters. The actual dimension of the site must remove the distance from the equipment to the fenceline(i.e.64.3 m-3.05 m). The incorrect initial lateral dimension caused problems, because if any receptor is located within 1 meter of the effective radius of a volume source a warning message is printed to the AERMOD output file and no concentrations are calculated for the source-receptor combination. This was the case during initial model runs. Six of the receptors did not calculate modeled impacts. The fenceline was modeled in the correct location, but the calculation of the initial lateral dimension was incorrect, and since has been corrected.

R. 7007.0850,subp. 1).The purpose of this document is to provide the legal and factual justification for each applicable requirement or policy decision considered in the preliminary determination to issue the draft permit. 1. General Information 1.1 Applicant and Stationary Source Location Table 1.Applicant and Source Address Applicant/Address Stationary Source/Address (SIC Code: 1442) Intex Corporation—Portable Box 260 Albertville, MN 55301 Contact:Wade VanVooren Phone: 763-428-8222 1.2 Facility Description The Intex Corporation-Portable facility processes crushed stone and sand for use in various construction applications.The facility processes include crushing,screening,and transport of crushed stone and sand. Diesel generators are used to power the equipment. Emissions are primarily dust from the processing and hauling of the material, and combustion byproducts from the generators. Pollution control measures include monitoring of material moisture content and the addition of water sprays to reduce the occurrence of fugitive dust. 1.3 Description of the Activities Allowed by this Permit Action This permitting action is a major amendment to allow additional equipment and increased production capacity,to revise permit language to establish procedures for equipment replacement, and to eliminate the requirement for computer dispersion as it has been completed. This permitting action defines the term Crushing Spread,which is the group of units that are used for nonmetallic mineral processing(and subject to 40 CFR part 60,subpart 000).The permit further limits the types and maximum quantities of each type of emission unit contained within a Crushing Spread, based on the results of the modeling. This permitting action also corrects the annual throughput limits for the facility and increases the number of Crushing Spreads allowed;the original permit incorrectly limited the throughput and hours of operation of the facility by not having those limits apply separately to each spread.

Part 70 Permit Program The facility is a synthetic minor source under the Part 70 permit program. New Source Performance Standards(NSPS) The facility is subject to NSPS,Subpart 000,Standards of Performance for Nonmetallic Mineral Processing Plants. Although the facility has diesel generators,they are not subject to 40 CFR pt.63,subp.ZZZZ because the generators are non-road (portable)engines and therefore,don't qualify as stationary engines under the NESHAP definition of 40 CFR Section 63.6675. National Emission Standards for Hazardous Air Pollutants(NESHAP) There are no National Emission Standards for Hazardous Air Pollutants applicable to the operations at this facility. Minnesota State Rules Portions of the facility are subject to the following Minnesota Standards of Performance: • Minn. R. 7011.2300 Standards of Performance for Stationary Internal Combustion Engines (While the generators are defined as non-road engines under federal rule, MN rules do not define stationary vs. non-road generators,therefore this rule applies in lieu of an applicable MN standard for non-road engines.) • Minn.

Technical Information 3.1 Calculations of Potential to Emit Detailed calculations were completed in support of permit limits and for the determination of PTE.The detailed spreadsheets are stored in the MPCA's Delta database.The permit contains annual throughput limits on material handling and fuel use to avoid permitting thresholds for Part 70 and/or PSD. 3.2 NAAQS This facility was identified as a facility that had the potential to violate National Ambient Air Quality Standards (NAAQS),and PER 001 contained a requirement to model to demonstrate compliance prior to receiving a permit amendment.The modeling was completed using AERMOD during the process for this permit.The results of the modeling included an hourly process throughput limit and a daily hours of operation limit.There is also a limit of 1 Crushing Spread at any location,and a separation distance of at least 0.5 km to avoid impacts that would affect the modeling.The summary report is included as Attachment 1 to this TSD. 3.3 Periodic Monitoring In accordance with the Clean Air Act, it is the responsibility of the owner or operator of a facility to have sufficient knowledge of the facility to certify that the facility is in compliance with all applicable requirements. In evaluating the monitoring included in the permit,the MPCA considers the following: • The likelihood of violating the applicable requirements; • Whether add-on controls are necessary to meet the emission limits; • The variability of emissions over time; • The type of monitoring, process, maintenance,or control equipment data already available for the emission unit; • The technical and economic feasibility of possible periodic monitoring methods;and • The kind of monitoring found on similar units elsewhere. The table below summarizes the periodic monitoring requirements for those emission units for which the monitoring required by the applicable requirement is nonexistent or inadequate.

R.7007.1300,Subp.3(H)(4). 3.5 Permit Organization In general,the permit meets the MPCA Delta Guidance for ordering and grouping of requirements,with the exception of GP 001 that has no units listed in the associated items because of the nature of the facility,subpart 000, and the extensive list of units which are stored in Appendix C of the permit. 3.5 Comments Received Public Notice Period:April 6, 2013—May 6, 2013 EPA 30-day Review Period:April 6, 2013—May 6,2013 No comments were received during the review period. 4. Permit Fee Assessment There are no additional points for this amendment.The modeling performed is for screening purposes only and therefore is not subject to additional points fees. 5. Conclusion Based on the information provided by Intex,the MPCA has reasonable assurance that the operation of the emission facility,as described in the Air Emission Permit No.99000208-002 and this TSD,will not cause or contribute to a violation of applicable federal regulations and Minnesota Rules.
