Topics Dust Control & Permits Dust Generating Operations/Standards When is a Permit Required Permit Application Process Approvals and Fees Common Permitting Issues

Dust Control & Permits PM10 Non-Attainment Area Quality Standard NAA classification means that air quality in a particular region does not meet federal health standards as defined by the Clean Air Act PM10 is defined as a suspended particulate with an aerodynamic diameter of <10 microns Control Goal – Limit the amount of particulate matter discharged to the atmosphere Sources Include: Fires, Unpaved Roads, Road/Home Construction, Industry, Vehicle Emissions, Agricultural Activities, Demolition Permitting ensures accountability and knowledge of mitigating control methods We Permit 3 different Areas (West Pinal, Apache Junction, Remainder of the County) West Pinal (Rule 4-3-180) Applicant Info: Owner, POC, Project Scope/Size, Work Practice Standards, Site Inspections, Control Measures, Work Practices, Trackout, Limit Trespass, Signage, Opacity Limits, Record Keeping, Signature Apache Junction (Rule 4-7-230, 226, 238) Applicant Info: Owner, POC, Project Scope/Size, Obligatory Work Practice Standards (Access control, Inactive/Post Operations Roadways, Bulk Material Op’s, Trackout, Signage, Training, Control Measures, Load Stabilization, Emission Mitigation, Sub-Contractor Registration, Opacity Limits, Active Area Stabilization, Record Keeping Requirements General Area/Rest of County We attain a signature after reasonable inquiry, that Project statements and information are true and accurate.

Dust Generating Operations/Standards Earthmoving Activities, Land Clean-up, Leveling, Back Filling Drilling, Construction, Demolition, Bulk material handling, storage and/or transporting operations Operation of motorized machinery used in construction, Establishing/Using unpaved parking lots, haul access roads in work site Installing initial landscapes using motorized equipment Standards Opacity Limitations West Pinal/General - Cannot exceed > 20% on the property Apache Junction – 0%/30 sec property line, >20% continuous/intermittent plume/time aggregate average Maintain Site Stabilization Ensure work site attains disturbed surface stabilization compliance at all times, including post-operation Drop Ball Tests utilized to measure stabilization Apache Junction Specifics – Maintenance of Threshold Friction Velocity, Vegetative cover standard, Erodible element coverage, Silt loading standards Track Out West Pinal/General - < 50 linear feet Apache Junction Specifics – < 25 linear feet, Limited daily bulk material movement, measured rumble strips/gravel pads/internal paving guideline, Remove all at end of day

When is a Permit Required Any worksite that covers an area of 0.1 acres or larger 0.1 acres = 4356 sq ft Calculation of land stripping/earthmoving surface areas: Include surface are for all disturbance activities Add 12.5’ to each side of structures, driveways, pads, etc. Parcels must be contiguous if multiple parcels are on one permit Calculation of disturbed area for trenching only projects: 726’ for trenches < 4 feet deep 363’ for trenches > 4 feet deep Calculations in ‘linear feet’ Land stripping and/or earthmoving permits cover trenching and stockpiling – (you do not need to permit them separately)

Permit Application Process Applicant Information: Applicant/Property Owner/Primary Project Contact Project Information – Parcel #, GPS, Township/Range/Section Project Scope – Type, Size, Road, Demo ID Earthmoving Disturbance Activities Work Practice Dust Control Measures – Dust Suppression Limit Trespassing/High Risk Day Stabilization/Signage Worksite Standards Liability Signature – Obligations and Affirmation Site Plot Map (Parcel/Work Location/Access/Neighbors)

Approval and Fees Approvals Fees Only trained Compliance Personnel can approve ‘Real-Time’ approvals possible with front desk applicants Target <24 Hour response to electronic submissions Fees Land Stripping - $75 (.1 to 5); $200 (5-10); add $200 for +10); $2000 (>100 acres) Trenching – From $50 (500 lf) up to $2000 (> 4 miles) Stockpiling – $50 for 10 cy; $100 for 100-500 cy; $150 for >501 cy Annual Block Registration - $2000 (installing utility lines) Late Fees - $25 for <5 acres; $100 > 5 acres

Common Permitting Issues ‘In-person’ applicant typically only represents Owner/Project Coordinator Site Plot Maps Missing Incomplete Submittals (Electronic) ‘Wrong Area’ Applications Name/Address/Phone/Email information missing or wrong Project Scope lacks pertinent detail Parcel/Township/Range/Section missing Missing documents/signatures Dust Control Measure boxes not checked Permit Expiration - Large construction projects personnel allow permits to expire
