WINNESHIEK COUNTY ZONING ORDINANCE

PROPOSED NEW SECTION 712

EXCAVATION AND MINING OF INDUSTRIAL MINERALS

The Board of Supervisors of Winneshiek County acknowledges the following concerns and findings regarding the possibility of silica sand mining, processing and transfer activity within the county:

1. The Winneshiek County board of supervisors, planning commission, businesses and residents spent many hours studying the potential impacts of mining, processing and transporting both construction and industrial minerals.

2. Winneshiek County has numerous natural areas, sensitive bluffs, karst features, trout streams, river watersheds, recreational trails, and wetland areas that justify and require special land use protection.

3. The primary land uses in Winneshiek County are for agricultural, residential, recreational, and commercial purposes, and not for significant industrial or manufacturing purposes.

4. Winneshiek County possesses some limited quarry and mining areas containing construction minerals which are mined for repairing and maintaining roads throughout the region, and providing bedding and other materials for farming and construction.

5. Businesses and residents of Winneshiek County are concerned about the potential adverse impacts from silica sand projects of (i) damage to township and county roads, (ii) reduction of water resources, (iii) unhealthy air emissions, (iv) contamination of streams and aquifers, (v) damage to bluffs and wetlands, and (vi) other environmental problems; if Winneshiek County should allow widespread and extensive mining, processing and transporting of industrial minerals to occur.

6. The University of Iowa Department of Occupational & Environmental Health is conducting a study in northeast Iowa of air emissions health impacts from crystalline silica sand, using funding from the US National Institutes of Health.

7. Businesses and residents of Winneshiek County are concerned that adding the mining and processing of industrial minerals to the already existing limited mining of construction minerals would create highly industrialized areas of the county, contrary to the goals and purposes contained in the county comprehensive land use plan.

8. In 2013, Winneshiek County approved a county-wide moratorium on silica sand mining for the purpose of determining the impacts of that proposed land use on county residents, businesses, agriculture, economy and the environment.

9. Winneshiek County is not attempting to regulate a mineral or product. Winneshiek County proposes to regulate mining and processing land use activity. The Winneshiek County board of supervisors recognizes that the land use operations for mining and processing industrials minerals are very different from the land use operations for mining and processing construction minerals. The industrial minerals mining land use operations (i) create more intense, larger-scaled industrial activity, (ii) consume more appropriated water, (iii) permanently expose and damage more landscape to scarring and alteration, (iv) require more concentrated heavy truck hauling traffic to single destinations, and (v) embrace other operational differences than the mining of construction minerals.

10. The Winneshiek County board of supervisors determines that large-scale mining activity and the mining and processing of industrial minerals are incompatible with (i) this county’s aging and fragile road and bridge system, (ii) this county’s comprehensive land use plan, (iii) the non-industrial character of this county, (iv) the need to protect the sensitive natural features prevalent throughout this county, (v) concerns about unhealthy exposure to ambient air emissions of mining industrial minerals, (vi) the need to protect sensitive streams, aquifers and water resources in this county, and (vii) the need to protect agricultural, residential, recreational and commercial areas.

11. This board of supervisors believes that the proposed county zoning ordinance is in the best interests of Winneshiek County, and will protect and preserve the health, safety, welfare, environment and economy of this county.

Based upon these concerns and findings, the Board of Supervisors of Winneshiek County approves, enacts and ordains this ordinance for the excavation and mining of industrial minerals, to be effective immediately following the publication and recording of such ordinance. The Board of Supervisors directs the Zoning Administrator to insert and integrate this ordinance of the excavation and mining of industrial minerals into the Winneshiek County Zoning Ordinance as new section 712.

PROPOSED NEW SECTION 712

EXCAVATION AND MINING OF INDUSTRIAL MINERALS

712 EXCAVATION AND MINING OF INDUSTRIAL MINERALS

712.1 Purpose

The purpose of this section 712 on excavation and mining of industrial minerals is to (i) minimize road and bridge damage from high-volume and heavy truck traffic hauling industrial minerals, (ii) protect natural landscapes from scarring and damage of excessive excavation and mining activity (iii) protect fragile karst features, water resources, aquifers, streams (including trout streams), and rivers from excessive contamination and appropriation, (iv) minimize soil erosion, (v) protect agricultural land and farming activity, (vi) protect existing recreational and tourist businesses, (vii) protect residents from unhealthy air emissions of mining activity, (viii) monitor and control the extraction and mining of industrial minerals, (ix) prevent the industrialization of agricultural, open space and residential communities, and (x) minimize land use conflicts.

712.2 Definitions

(a) Excavation and Mining. The term “excavation and mining” includes any process or method of digging, excavating, mining, drilling, blasting, tunneling, dredging, stripping, or removing industrial minerals from the land surface or underground. The term “excavation and mining” applies to all activity occurring at excavation or mining sites, including sites commonly identified as quarries and sand pits.

(b) Construction Minerals. The term “construction minerals” includes natural common, low-grade quartz rock, stone, aggregate, gravel and sand that is produced and used for local construction purposes, including road pavement, unpaved road gravel or cover, concrete, asphalt, building and dimension stone, railroad ballast, decorative stone, retaining walls, revetment stone, riprap, mortar sand, construction lime, agricultural lime and bedding sand for livestock operations, sewer and septic systems, landfills, and sand blasting. The term “construction minerals” does not include “industrial minerals” as defined in Section 712.2(c).

(c) Industrial Minerals. The term “industrial minerals” includes naturally existing, low impurity, high quartz level silica sand, quartz, graphite, diamonds, gemstones, kaolin, and other similar minerals used in industrial applications. Industrial minerals may be used, among several industrial uses, as a proppant for the hydraulic fracturing of shale for oil and gas production. Silica sand is categorized as an industrial mineral by the North American Industry Classification System under classification no. 212322. The term “industrial minerals” does not include “construction minerals” as defined in Section 712.2(b).

(d) Processing of Industrial Minerals. The term “processing of industrial minerals” includes the processing, washing, cleaning, screening, filtering, sorting, stockpiling and storage of all excavated or mined industrial minerals.
