City Council Agenda Report
City of Scandia
14727 209`h St. North
Scandia, MN 55073 (651) 433-2274
Action Requested: Consider the application for an Annual Operator's Permit (AOP) for
the Tiller Corporation sand and gravel mining operation located at
22303 Manning Trail.
Deadline/Timeline: 120-day review period ends June 8, 2011. The AOP will cover the
mining season through December 31, 2011.
Background: • The mining operation received a Conditional Use Permit(CUP)
under the city's Mining Ordinance in May, 2008. The CUP and
the ordinance require issuance of an AOP.
• The Tiller application includes the adjacent site formerly operated
by Dresel Contracting, Inc. on 218�' Street, west of Lofton
Avenue. The AOP must also comply with the CUP issued for the
former Dresel site.
• The Council considered the application at its March 15, 2011
meeting and postponed action to the April 19 meeting. Staff was
directed revise the conditions of approval to clarify that the
proportionality of mining and reclamation activities must occur
over time, not year by year. After that meeting, Tiller Corp.
submitted the attached letter describing what they explained
verbally at the March meeting. Condition#4 in the draft
resolution approving the AOP has been revised to read as follows:
"The applicant shall maintain proportionality of mining and
reclamation areas over time, as described in the letter from Tiller
Corporation dated April 13, 2011."
• Also at the March 15 meeting, the Council was addressed by Mr.
John Lindell who requested that a statement in the AOP
application concerning expansion of the asphalt plant be removed,
or that language should be included in the approval indicating that
the city does not agree with the statement. He submitted a similar
comment in an e-mail dated April 8, 2011. The specific language
he objects to reads as follows: "the site operates a permanent hot-
mix asphalt plant and the plant was in operation at the time the
City adopted its mining ordinance. Therefore the plant may
expand in the future subject to the setbacks set forth in Section
7.1(1) of Ordinance No. 103. "

• Staff has reviewed this comment and continues to recommend that
no changes be made in response. The language in the AOP
application is factual and simply quotes the ordinance, Section 7.1
(19)(B).
Recommendation: Staff recommends that the Council approve the AOP with conditions
as stated in the draft resolution.

Honorable Mayor and Council Members
City of Scandia CITY OF SCANDIA
14727 209th St.N
Scandia, MN 55073
Dear Honorable Mayor and Council Members:
At the March 15� 2011City Council meeting Tiller Corporation (Tiller)was asked to explain the
proportionality of the mining and reclamation activities at our Scandia facility. To start this
explanation we offer a brief history and description of our mining and reclamation operations.
In the past we have reclaimed significant areas mainly to the north and west of the stockpile
and processing area.Also,overburden was removed from areas to be mined and was stockpiled
on site in screening berms to be used later for reclamation. These screening berms were
required by Washington County and were not intended to be used for current reclamation. This
material is reserved for final phases of reclamation once mining is more or less complete. After
these screening berms are established,overburden that is being removed is placed directly into
areas that are being reclaimed.
Mining occurs above and below groundwater at our facility. Aggregate is excavated above
groundwater using front end loaders. A dragline or excavator is used to excavate material
below groundwater. Mining below groundwater typically occurs once a mining facility begins
to mature. A fairly large floor area is needed for a stockpile area,a processing area and an area
to begin excavation below groundwater. Our Scandia facility has reached the stage where the
floor area is large enough to accommodate mining below groundwater. Due to the variable
nature of the aggregate deposit,it is beneficial to mine above and below groundwater
concurrently in order to obtain the proper blend of aggregates.
This is important to understand because there are very limited areas where mining is complete
and reclamation can occur. However once mining reaches the perimeter of the site and is
completed,reclamation is performed in conformance with the approved reclamation plan to
allow for future development of the land.
There are primarily two types of reclamation activities that occur at this facility;the ongoing
reclamation activities and the mass reclamation activities. The ongoing reclamation activities
April 13, 2011 ��
Page 2 of 2
generally occur each season. Often materials suitable for reclamation but not suitable for
aggregate production are encountered and these materials are used for reclamation. In
addition various local construction projects will encounter materials not suitable for the
specific project and/or excess materials. If these materials are suitable for reclamation we will
accept them for placement in our ongoing reclamation area. In our 2011 Annual Operating
Permit Application we have identified the area where the ongoing reclamation activities are
expected to occur.
The mass reclamation activity occurs concurrently with removal of overburden from an area in
preparation for mining. We commonly refer to these combined activities,overburden removal
and reclamation,as a striping/reclamation project. We do not have plans for this type of a
project for 2011. These projects occur approximately once every five to seven years depending
on aggregate demand. During these projects it is not uncommon to have suitable material
volumes well in excess of 100,000 cubic yards available for reclamation. It is our intent and
goal to proportionally open new areas for mining and reclaim areas during these projects. It is
important to note that these two areas will not always be exactly the same size in area.
Overburden removal and reclamation are three dimensional. In other words the overburden
removed from say seven acres may or may not be enough and may be more than enough to
reclaim exactly seven acres. However when you consider the mass reclamation combined with
the ongoing reclamation there is proportional newly opened areas and reclaimed areas.
Tiller was actively involved with the City's staff, Planning Commission, Mayor and Council
during the development and adoption of the current mining ordinance. Because of this
involvement Tiller is aware of the proportionality language in the ordinance. At the time the
ordinance was adopted we were comfortable with the language because as explained above we
are reclaiming areas proportionate in size to new areas being opened for mining.
Thank you for your time and consideration. If you have any questions please do not hesitate to
call. I may be reached at(763) 425-4191.
Sincerely,
Tiller Corporation

Subject: RE: Some items
John-
1) We will consider your suggestion. Tiller's statement that the asphalt plant may be expanded in the future is
factual, subject to ordinance requirements. It would require an amendment to their CUP, which has not been
approved or applied for. Any statements in their permit application do not change that fact.
2) If you talked to Frank Langer this weekend I'm sure he may have already handled your concern, or explained
that you may come to tonight's Board of Appeals meeting (5 to 6 pm.)
3) The City is only responsible mailboxes if they were hit directly by a snowplow. If you believe that yours was hit,
please arrange with Steve Thorp to have someone take a look at the remains to verify that. There were a lot of
mailbox posts this year that were pushed over because of the weight of the snow. The city is not responsible for
those.
4) Yes, a building permit is required for re-roofing. If you hire a contractor, they should apply for the permit. Give
Steve a call if you have questions.

Subject: Some items
Anne, I have some questions and comments for various issues and thought I would put them all in one email.
1) Tiller AOP-I would like the following proposed language included in the Councils decision altematives for this item that
reflects comments I made the at the last meeting to discuss Tiller.
"Approval of the annual operating pernut for
Tiller is not an approval of the contents and representations in the application which are not affirmatively being approved.
Specifically
the representations in the application that Tiller has authority to expand its asphault plant based on the fact it currently has
authority
to have an asphault plant is not accepted by the Council." (Its not a issue at this time so there shouldn't be any objection)
I expect to address this issue at the meeting but I wanted specific proposed language available for the Council's consideration.
1
2) Is the Board of Appeals meeting already set for who can be considered for appeal? I expecUwant to appeal my valuation.
I will be talking to Langer over the weekend on this.
3) I read about mailboxes being tipped or damaged and that Scandia will provide some compensation for that.
If so,I want to apply or take advantage of that. I think the post on my mailbox is broken from snowplowing.
4) I will be reshingling my roof. I assume there is a permit required for that and probably will need discussions with Steve.
What is the process for the pernut?
thanks,
