  1. So, you just got a GCP – 5… What Now?

  2. GCP PERMITS • GCP Application and Compliance Requirements • What to Expect When the Inspector Arrives

  3. General Construction Permits were developed to create a streamlined permitting process for typical small sources. • What are the advantages?

  4. GCP ADVANTAGES • Fast – 30 days • Simple – no modeling • Less expensive - $3400 • Predictable – published in advance

  5. BUT… • GCP permits contain many restrictions that may or may not be in a regular construction permit. • Production rates • Hours of operation • Recordkeeping

  6. WHY? • GCP permits are based on a generalized computer model. • GCP permits emphasize respect for neighbors.

  7. Do I Want a GCP? • GCP – typical facility in a low-impact location. • Regular construction permit – site specific for location, equipment, production.

  8. GCP -5 Permits – Who Qualifies? • Concrete production facilities • No more than 2400 yards/day • Conventional equipment • No slag, asbestos, radionuclides or Hazardous Air Pollutants

  9. Can I have more than one kind of permit? • Can I co-locate facilities? • Yes – with restrictions

  10. Public Notification General Information SIC Code – 3271, 3272, 3273 Facility Status and Location Operating Schedule Production Rate Restricted Area Disturbed Area Storage Piles Haul Roads Equipment List and Capacities Emission Controls Drawings and Maps Plan of Operations Contact Name Fees - Yes Modeling - No APPLICATION REQUIREMENTS

  11. Site Restrictions • Minimum distance from Class 1 Area – 3 miles • Minimum distance between equipment, piles, roads and fence – 42 feet. • (Other GCP permits require ¼ mile separation from nearest residence.)

  12. Emission Restrictions and Conditions • Dust control on haul roads; stockpiles in bunkers • Dust controls on truck loading points: • Washed sand • Control stockpiles during hours of operation • 15% of mix water in truck before dry materials • Inject cement through concentric boot • Install commercial negative pressure canopy over loading point • Filter on silos • Filter efficiency 99.9 % • Recycle filter fines into a controlled silo

  13. More Emission Restrictions • No visible emissions from filters and silos • Zero visible emissions shall cross the plant boundary • Silos alarm at 95% of capacity • Base course and watering on haul roads (or better) • Surfactant, paving, wheel washing required inside ¼ mile of occupied structure • Haul roads limited to one mile • Maintenance of mixing facilities • Filter or baghouse on all silos if production > 1920 tons/day.

  14. MONITORING • Activity status and filter differential pressure each time a silo is filled or truck is filled; • Recorded by CEMS or datalogger; • Confirm filter operation within manufacturer’s specifications. …

  15. Recordkeeping

  16. RECORDKEEPING • Compliance based on inspections – no periodic reports to the Bureau; • Maintain records: • Two years • On site or at local business office

  17. Records • Actual dates/hours of operation • Monitoring records • Weekly production; monthly rolling average • Haul truck records • Fuel delivery manifests

  18. Records • Quantity and frequency of water or surfactant on roads; • Haul road sweeping; • Other haul road measures; • Maintenance records; • Loading canopy system

  19. Wrapping UP…

  20. How do we measure success? • New Mexico skies are blue - but they can be bluer. • New Mexico is a great place to live - but it can be better. • New Mexico workers work safely - but they can be safer

  21. How does the Air Quality Bureau measure success? • Voluntary compliance • Partnership - ask for help • Satisfied neighbors
