Summary
At its meeting on September 17, 2007 the City CouncIl provided direction to staff and the applicant to
address concerns raised by adjacent property owners relative to the outdoor sandblasting, cutting, and
other processes. The applicant, Stonewoxks, requested four weeks to evaluate options and prepare a
response fox the Councils review, recognizing that there are concerns related to the sandblastuig
operation in addition to the akeady understood noise and hours of operation concerns. Their proposal
includes bexming and construction of a building. '1"hese two additions, they believe, will address the noise
and dust issues associated with the operation of the business, while not being too disruptive to their
business flow.

Stonewoxks originally requested a Conditional Use Permit to memorialize and confirm the operations of
their business. In 2005, a CUP was granted allowing the business to operate. Over the last several
months, staff has received a number of complaints from one property owner regarding noise and hours
of operation. The CUP does not specifically regulate the hours of operation, nor does it say whether or
not work can be performed outdoors. While discussion during the meetings did include the location of
outdoor functions, there was no condition imposed.
Public Comment
Public comment during both the PC and CC meetings in September noted concerns with the noise, hours
of operation, and dust that were all part of the business. There axe two property owners primarily
affected, both were in attendance at the meeting, in addition to a renter of one of the properties. One of
the pxopext5~ owners provided information that suggested that sandblasting operations be located in a
controlled environment A copy of this information is attached.
Other residents commented on the general noise that is a part of the sandblasting operation.

Subject: FW: Stoneworks Information
Jeremy,
Following is a description of the proposed changes to be made at the Stoneworks Architectural Precast
operation.
1. We will construct an 8' high berm, located along the North and East property lines of our site.
This berm will aide in limiting the noise associated with our operation, and will serve as a barrier
to limit visibility.
2. We will construct a 30' X 50' fabric covered building to enclose our sandblasting and cutting
operations. (similar to the structure at the City Maintenance site) This building will include a
dust collection system. The anticipated construction schedule would be 6 weeks to fmish this
project. We will continue to operate our power-washing finishing process (about 5% of our
business) outside. The power washing process is not a loud noise generating procedure.
3. We will propose the following hours of operation -
Inside Operations - 6 am - 6 pm - 7 days a week.
Outside Operations -lam - 6 pm -Monday thru Friday, Sam - 5 pm -Saturday, and 12pm - 5
pm -Sunday.
As suggested by the City of Elk River Environmental Administrator, Rebecca Haug, we
contacted Matt Ledvina with Natural Resource Group regarding noise and dust testing. He
stated enclosing the sandblasting and cutting operations would prohibit the need to do this
testing.
If any additional detail is needed regarding this matter, please contact me. I believe the proposed
changes will effectively address the noise and dust concerns of our neighbors, and allow us to
operate our business adequately.
Sincerely,
Kirt O'Konek

the sandblasting operation, in addition to the already understood noise and hours of operation concerns.
Stoneworks desires to fully understand Councils concerns before proceeding with plans to address those
recently raised. Stoneworks has requested the Council table formal action on the request after the public
hearing and Council discussion, with the intention of coming back to the Council in October.
Summary
Stoneworks is requesting a CUP to memorialize and confirm the operations of their business. In 2005, a
CUP was granted allowing the business to operate. Over the last several months, staff has received a
number of complaints from one property owner regarding noise and hours of operation. The CUP does
not specifically regulate the hours of operation, nor does it say whether ox not work can be performed
outdoors. While discussion during the meetings did include the location of outdoor functions, there was
no condition imposed.
The Planning Commission recommended approval for the Conditional Use Permit memorializing the
operations parameters fox Stoneworks:
Hours: general operation 6a to 6p, 7 days per week
Hours: outside operation 7a to 6p M-N, 8a to Sp S/S
Outside operation to uiclude cutting sandblasting, power washing. Outside operations shall
be completed in an enclosed area to meet ox exceed regulatory standards.

5. Downcast building lights only, no other site lighting is allowed.
Public Comment
Public comment was received noting concerns with the noise, hours of operation, and dust that were all
part of the busuiess. There are two property owners primarily affected, both were in attendance at the
meeting, in addition to a renter of one of the properties. One of the property owners provided
information that suggested that sandblasting operations be located in a controlled environment. A copy

Other residents commented on the general noise that is a patt of the sandblasting operation.
Plannina Commission Discussion
The Planni>a Commission received the public comments, and discussed appropriate conditions to
protect the adjacent residents. Although not a part of the recommendation, the Commission suggested
that the hours of operation be consistent with those hours recently imposed on Tiller (7-7 M-P, and 7-
Noon on Saturday) The Commission also discussed moving the operation to another location within the
site, but ultimately required an enclosure and necessary modiEcations to ensure the operation meets ox
exceeds regulatory standards.
OSHA publishes Minnesota Noise Standards fox residential areas, establishing allowable noise levels fox
residential areas. These levels are measured at the property line near residences, and are as follows:
Daytime (Minnesota standards define daytime as 7 a to 10 p) 65 decibels, and nighttime is 55 decibels.

Dangers of Sandblasting
Protect your health from the dangers of sandbtasttngt Sandblasting with silica sand
makes a lot of dust. The realty dangerous st tff is so fine you can't see it. (3reathing air
containing this fine dust can damage your lungs. You must always wear a helmet when
sandblasting and there is only one type of helmet that will protect You. The type of
helmet you must use is a helmet that rs supplied with dear air. The helmet must be a
goad fit and in good worlvng condition.
r A damaged helmet fs dangerous. ^o not use equipment that has parts mtssing
or damaged.
• The helmet must also fit well so that dangerous dusty afr does not teak Into the
helmet while you are working,
. The air supplied fn your helmet must be dean and free of dangerous dust. To ha
sure that the air is clean a filter must be fitted in the tine between the compressor
supplying the air and the helmet_
. Your employer is required, by law, to prove you with the forced air full face
helmet and the clean air supply to go with it He is also required to Bain you how
to use it and tww m maintain it and keep it clean.
. Your employer must check the dust tevels in the area where sandblasting is
being lane.
. Af least once every three years, your employer 3s required to provide you with a
medical check-up, tncludtng an x-ray, to make sure that your lungs are not
damaged.
If you are working in a sandblasting area, even if you are only cleaning up, you must
also wear a respirator. Remember, THE QgNGEROUS ~ttST f5 FNYI518LE. Cleaning
up can make the dangerous dust airborne and breathable again. If the job site can be
wet down you should we down before starting clean up. The dangerous dust can get
into your clothes and can wntinue to get airborne as you move. Don't try to blow it off
with compressed air, this only stirs it up worse. tf you can, change Into clean clothes
before going home,
Do Not Forget!
tnvislble dangerous dust fs made when sand blasting with silica sand.
You must wear an air supplied helmet when sandblasting.
Your emptoyer knaves the equipment and training you require. If you have any
doubts or questions ask your boss.
When you use the right equipment and are properly trained in its use and maintenance
there will be very little danger to your health tram sikca dust.

What is Sitirasis?
SHlcosis is a pneumoconiosis, or Yung disease, that is causer! by the
inhalation of lode, carcinogenic crystalline silo dual panicles.
Silicosis is incurable and irceversklle. SifNx 's a naturally ocaening
minaret that ie found 'm quark, granite, and other rocks. it is one of
the mast wmmon minerals in lire earth's crust, but k is only harmful
when small particles bl R are released krto the air and inhaled.
Unforiunatety, many Jabs require workers is use klols and
equlpmentthat introduce dangerous kevels of crystalline si€rca clue!
iota the air. Once sbica dust is airborne, silica exposwe is difictllt to
avoid, especially when working in tlght areas with high levels of
silica dust for prolonged periods.
Slllcosis has affected miners and !base who work around silica dust
fa' hurl reds of years. Once the crystalline silica tlust is inhales, it
wodcs fts way ktW the lungs, where it leaves scarring that experts
think may be caused by sharp edges of the tiny particles
themselves. Silica exposure artd saw disease Often lead to ether
lung diseases as vreU. Sorne of 1tlese resp'vatory dseases and
wmplications include: lung center, tubercubs~, fibroses, bronchitis,
and emphysema.
to cases of silicosis pneumoconiosis, the panicles of crystalline
slllga dust aritate the tiny alvedl ak sacs in the lungs. White blood
cells then aUack and surround the foreign particles, and then they
die. The Irritated area condnues tG cause white blood aces bo further
inFlame the area. C-ventualty, fibrous, scar-like tissue sunaunds ttre
area and can cease the problem. Untwlunately, this fituous tissue
destroys dIe ability cl the affected area to process oxygen. Often,
the development of flhrous tissue doesn't stop and can spread
throughwt the lungs. Silica disease often continues b progress
even after exposure to crystatllne slllra tli15t ceases. Often

Dangerous Oecupadons
There are nearly two rtiillion workers in the United States with
occupations that lead m crystalline silica dust exposure. silicosis, or
silica disease, is especle~y common among the workers whose
occupations expose themto extremely high levels of crystalline
silica dust far long durations. Some of the oorrxnon occupations or
types of workers at risk of sJca disease due th cystallinesilica dust
exposure tndude:
» Sandblasfirw r Sand6ksters
» Shlm~ard Workers
a Mining !Miners
. Foundry Workers
a SEonecukers

The fnllowirg ocarpations ere discussed in furtherdetail bepuse
lney pose the greatest rtsks of the pneumoconiosis silicosis, or
slice disease. These occupations pose the highest crystalline sBip
dust exposure kevels, are pertonnetl In goody ventilated areas, and
surnound ttta worker In a cloud of silica dust for prdonged pedods.
Sandbiasling -Sandblasting Disease
There is a reason chat silVeosis is wmmonty refened to as
sandblasting disease. Sandblasting is one of the highest risk
occupations when it mores W silicosis and crystalline silica dust
exposure. One of the main reasons is the high concentration of
quartz or other high crystalline slice wrAent minerals in the
abrasive sands used in sandblasting operations. Roughly 5 percent,
or 100,000, of the warkers in the United States that are exposed tc
crystalline silica dust on the job are employed as sandblasters.
Many other acaepaUons irtvotve sandblastng on a partdma heels.
Sandblasting is typic~ly used la dean ar remove anything from
automobfie paint to sand from famdry castings. Sand (often
containing high rystalline slice concentration} is forced inm a high-
pressure stream with compressed air or steam and used as an
abrasive agent for many types dcleaning snd surface preparation
jobs. Silica sand can break tlown to very small partides during
sandblasting operations. This freshly ground silica tlust lands to
lead Oo the quicker-to-progress acute and accelerated forms of
sliicosis or sandbtasistg disease.
SNdfes have shown that many sandblasters Fnve already died of
silicosis or silica disease. Unfodunataly, these studies also project
that many more will likely die of sandblasting disease caused by
inhalation of extremely dangerous levels of erystalltre silica dust
Others will likely die of some of the complications related io
silicosis, Tike lung cancer and tuherculos's.
