1 RESPONSIBLE MANAGEMENT OF OUR NATURAL RESOURCES A Staff Presentation by Jeff Gamel and Heidi Tschudin March 23, 2009

2 Early Mining Practices The Gold Rush Era Prospecting Mining Towns Hydraulic Mining Dredging

3 Dredging for Gold

4 Dredger Tailings

5 Suburban Development s

6 What are Aggregates? Sand, Gravel and Crushed Stone Comprise 94% of Asphaltic Concrete and 80% of Ready-Mixed Concrete Concrete aggregate is aggregate that meets quality standards for use in Portland Cement Concrete (PCC) Used in Roads, Buildings, Homes, Hospitals, Schools, Sewer Systems, Offices, Churches, Sports Stadiums and all public and private infrastructure

7 Importance of Aggregate Materials A Convenient Source of Construction Aggregates is Vital to a Healthy and Prosperous Economy 100 tons of Aggregates for the Average Home 11.5 Million Tons of Aggregates per Year Needed for the Sacramento Region to Meet Current Construction Needs 7 Tons per California Resident per Year to Meet Current Construction Needs 60% of all Construction Aggregates are used for Public Works Projects

8 Where are the Aggregate Materials?

9 Historic American River Channels

10 Historic American River Cross Sections

11 Reserves Lost to Urbanization About 140 Million Tons of Construction Aggregates Bordering Highway 50 Have Been Lost to Urban Development Pressures Mather AFB has Helped Protect the Reserves Due to Safety and Noise Regulations

12 Alluvial Mining in Sacramento Today

13 Available Supply In 2006, CGS Determined that Available Aggregate Resources in the Sacramento Region Were Less than 10% of the 50-Year Need Permitted Reserves Exhausted in 8-10 Years Under Current Economic Conditions

14 Out-of-County Sources

15 Implications of Importing Aggregates $0.15/Ton per Mile to Transport Increased Traffic Congestion Increased Roadway Maintenance Increased Air Quality Impacts Increased Construction Overruns Higher Costs to Consumers and Taxpayers

16 Regulatory Structure 1974 Aggregate Resources Study (ARMTAC) 1975 Surface Mining and Reclamation Act (SMARA) 1985 State Mineral Land Classification 1986 Aggregate Resources Report (ATAC) 1999 State Mineral Land Classification 2008 Zoning Code Update Mining Standards

17 1974 Aggregate Resources Study (ARMTAC) Tasked to Identify Aggregate Resources, Assess Future Needs, and to Develop Regulations Established a New GP Land Use Category Established a New Combining Zone Established Zoning Code Standards for Mining and Reclamation Required Performance Bonds for Reclamation

18 1975 Surface Mining and Reclamation Act (SMARA) To Ensure that Significant Mineral Deposits are Identified and Protected, and that Mined Lands are Reclaimed Mining is Defined as the Exportation for Commercial Purposes of Material in Excess of 1,000 cu. yds. Reclamation Guidelines Intend that Mined Land be Returned to a Useable Condition and in a Manner to Protect the Public Health and Safety Local Jurisdictions are Expected to Comply with SMARA by Implementing Regulations through Land Use Ordinance

19 1985/1999 State Mineral Land Classification SMARA Requires the State Geologist Classify Lands into Mineral Resource Zones (MRZs) Primary Goals are to Recognize Resource Potential, and Consider in Land Use Decisions Within 12 Months, Lead Agencies are to Incorporate Policies to Protect Resources in General Plan

20 2008 Zoning Code Update Mining Standards Expanded Those Uses Permitted in the SM Zone with a Use Permit (Processing Plants, Ready-Mix and Asphaltic Concrete, Recycling, Dimension Stone, and Conveyor Systems) Concrete Products Manufacturing (Concrete Pipe, Roofing Tiles, Underground Utility Boxes, and Bagged Aggregates) is Postponed for Further Study Require Greater Setbacks from Adjacent Dwellings Add Standards for Hard Rock Mining

21 Entitlement Process for Typical Mining Projects Community Plan Amendment Rezone Use Permit Reclamation Plan

22 Potential Issues Truck Traffic Road Maintenance and Repair Noise Lighting Hours of Operation Processing Plants
