Mr. Ritsen,
Thank you for your comprehensive response to the anonymous letter that we received. It appears that the concerns
brought forth have been addressed and will continue to be a priority for your company. Our Engineering Division has
verified that proper erosion control measures have been implemented on the site. We appreciate your continued efforts
to make this very conspicuous project safe and compliant.
If you would like to discuss this further do not hesitate to contact me.
Sincerely,
Dale

Mr. Schoeppner,
I received and reviewed the letter of concern you sent to our office. I can appreciate these concerns. Rest assured, we
want the city and your residents to be comfortable in regards to our operations. They are prudent and above and
1
beyond regulatory standards but that does not mean we will overlook a comment when it’s brought to our
attention. Our staff and workforce take pride in our work and our valued reputation.
The letter addressed a few different topics. I will address them each individually and you and I can discuss them from
there.
1. Asbestos Containing materials in the structure.
All regulated asbestos containing materials (RACM) have been removed from the structure prior to demolition
operations. ACM removal operations started in November of 2014 and operations completed in January of
2015. All asbestos containing materials were identified by Braun Intertec in a destructive asbestos and
hazardous materials survey. We have a copy of the document if you would like to review we also keep a copy at
the site for our workforce communication. Near the end of asbestos removal operations the site was visited and
inspected by the Minnesota Department of Health without any objections . All RACM material were disposed of
at SKB Landfill in Rosemount MN and we have all disposal manifests in a closeout document from the contractor
hired to perform the work.
The building also contains limited amounts of non-friable asbestos materials that will be removed during
continued demolition activities by means approved by the regulating agencies.
2.Dust from operations
As addressed above, we have laborers on the site wetting materials as they are being demolished. Since it has
been a dry spring, I believe some of the residual dust from vacant lots and surrounding open areas could be
causing the concerns. Rachel Contracting also has an oscillating water atomizer. This machine looks like a
snow machine you would see at a ski hill. It continually mists work operations with particulated water, which
we get from a hydrant on the site. If need be we will water down surrounding open areas and vacant lots until
we get our much needed spring rain.
3.Storm Water
The site has a SWPP and a NPDES permit number C00039766. I have verified that all storm water controls are in
place per the permit requirements. We have Inlet protection in 24 catch basins around the site and we will be
adding a fiber roll around the concrete that will be recycled on the site. We inspect our controls on a weekly
basis and after every ½” rainfall event. As described above, we will wet vacant lots and open areas if we
continue to see dust getting stirred up by prevailing winds.
I hope this addresses and alleviates each concern that was brought to your attention. We strive to bring communities
safe and compliant projects so I would like to keep an open door to you if any further concerns come up during the
process. My contact info below is current.
