contemporaneous reclamation would be employed so that 40 to 50 acres would be open at any
given time. They will be mining dolomitic limestone to be used as raw material for concrete
products, construction materials and agricultural liming material. The limestone will primarily be
used for concrete products for the County Materials manufacturing facilities in Roberts and Eau
Claire, WI. If a conditional use permit is granted, County Materials will remove their operation
from the Schoeder quarry in Rock Elm. The proposed operation in located in the Town of Spring
Lake. The property is zoned General Rural where nonmetallic mining is conditionally permitted.
The site is currently woodland and agricultural use. Approximately 30 acres of woodland will
remain undisturbed. The proposed access driveway is located near a vacant parcel with an
abandoned house. Residences are located in close proximity to the proposed access on the
opposite side of Hwy 128. County Materials will have no more than 9 trucks operating and these
trucks will operate approximately 15 to 20 minutes apart during peak working times. The site is
located in the Eau Galle River watershed. The nearest point of the quarry will be 1000’ from the
river. Currently the site has runoff that directly reaches the River. County Materials is proposing
to install a stormwater pond that will limit the amount of water that reaches the Eau Galle River
from the site. The storm water pond will be constructed on the west side of the site. This pond
would have certified engineer design and the capacity for a 100 year storm event. Stormwater
berms will be installed in areas of possible overflows. Other 8 ft earthen berms will also be
installed to protect the surrounding residences. Access to the mine is proposed off of State Hwy
128. The applicant has contacted the DOT about an access but will not apply for one until they
are granted the mining permit. Almost all of the truck traffic along Hwy 128 will be to the north
as the trucks travel to and from the Roberts and Eau Claire facilities. The access will have a gate
which will be locked when the site is not in operation. The quarry floor will be at 1045 ft, the
water table elevation is approximately 945 ft. The rock is removed by drilling and blasting. It is
processed and stockpiled on site, and hauled primarily to concrete products manufacturing plants
in Roberts and Eau Claire. The drilling and blasting is performed by state licensed contractor.
Typically 150,000 to 200,000 tons of material, dependant on market conditions, will be exported
form the site annually, representing an average of 2 loads per hour. Dust will be controlled on-site
by improving roadways with gravel and applying water on an as-needed basis. Activity on the
site will typically occur during the construction season, March to November. However, some
hauling of processed material may occur December through February, as conditions warrant.
Hours of operation are proposed 6am to 9pm Monday through Friday, with occasional Saturday
operations 8am to 5pm during the construction season. Typical hours will be 6am to 6pm
Monday through Friday. The applicants are requesting to have hours until 9pm for the times
when they are crushing. County Materials contracts their crushing, crushing will take place on the
site for 2 to 4 weeks and then there will be no crushing activity for approximately one month.
There will be no activity on the site on Sundays or holidays. They will employ up to six people.

address the practices for fueling, lubrication and repair of the equipment. Fuel storage will be
limited to one 500 or 1,000-gallon portable off-road diesel fuel tank for equipment compliant
