Air Permitting and Compliance Clean Air Act Basics • CAA History • NAAQS • NSPS/NESHAP • 1970 Orig. CAA, 1977 CAAA (PSD), 1990 CAA Amendments
Clean Air Act Basics • CAA Dates Back To 1970’s • 1970 CAA Contained NSPS @ Part 60 & NESHAPS @ Part 61 = Risk-Based/Few Perfect Stds. Covering Only 8 HAPS • Great Deal Of Non-Compliance W/ Orig. Intent Of 1970 CAA • Only Handful Of NSPS/NESHAPS Promulgated From 1970 To Mid 1980’s • CAA Amended 1990(Former Pres. Bush)
Clean Air Act Basics Con't. • 1990 CAAA Designed To Curb 3 Major Threats To Human Health & Environ. = Acid Rain, Urban Air Pollution, & Toxic Air Emissions • National Permits Program Established To Make Law Workable & Enforceable • Phase Out Ozone-Depleting Chemicals, Add Research & Development, Add RMP

Clean Air Act Primer • Regulation Of Air Emission Sources: Emission Stds., NAAQS • Emission Limits: Lbs/Hour, Tons/Year, Lbs/Ton, Lbs/MMBTU, % Opacity, % Efficiency, etc. • Basis For Limits: 1970 NSPS @ Part 60, 1970 NESHAP @ Part 61, SIP’s, 1990 NESHAP (Stationary Source Categories), Acid Rain @ Parts 73 & 76, Stratospheric Ozone @ Part 82
Clean Air Act Primer Con't. • What Is Ambient Air? That Portion Of The Atm., External To Bldgs., To Which The General Public Has Access --- Typically Site Boundary Outward If Have Perimeter Fencing --- Attainment Demonstrated Via Air Disp. Modeling & Ambient Monitoring • NAAQS: Micrograms/Cubic Meter & Based On “Acceptable Risk” – (1 : 1,000,000 CR) • NAAQS Basis: NAAQS @ Part 50, PSD 1977 CAAA @ Part 52, & State Stds.
Clean Air Act Primer Con't. • Primary NAAQS: Set @ Levels “Allowing An Adequate Margin Of Safety…Requisite To Protect The Public Health” • Secondary NAAQS: Set @ Levels To Protect “The Public Welfare” • Regulated Pollutants: PM-10 (PM-2.5 Soon?), SO2 (Sulfur Dioxide), NO2 (Nitrogen Dioxide), O3 (Ozone/VOC), CO (Carbon Monoxide) & Pb (Lead) --- “Criteria Pollutants” = TSP/PM, SOx, NOx, VOC, CO & Pb (Const. Permits)
Clean Air Act Primer Con't. • SIPs: Attain/Maintain NAAQS, Establish Emission Limits, Review Impacts Of New Growth, Revised As New Regs. Are Passed • PSD: Prevent Sig. Deterioration = Const. Permitting Via 1977 CAAA --- Based On “Potential Emissions”, Regulates Emissions & Ambient Air Quality, Affects Lg. Sources • PSD Goals: Allow Economic Growth While Protecting Air Resources, Protect Public Health & Welfare, & Enhance Air Quality
Clean Air Act Primer Con't. • PSD Review Req.: Ambient Monitoring, Dispersion Modeling, Control Device Review, Additional Impacts, Class I Assessment (Not Title V Class I) = Impacts To Soils, Plant Life, Visibility, --- National Parks, etc. • 1990 CAAA Overview (11 Titles - 3 Main): • *Title I = Attain/Maintain NAAQS • *Title III = HAPs/Air Toxics • *Title V = Permits/Operating Permits
Clean Air Act Primer Con't. • Title I (Attain/Maintain NAAQS): *“Attainment” Of NAAQS Req. For Const. Permitting (i.e., PSD)To Apply *”Non-Attainment” Of NAAQS PSD Not Applicable & Any Proposed Project/Mods. Must Actually Reduce Overall Emissions
Clean Air Act Primer Con't. • Title III (HAPs): *Previous Approach = Risk-Based, W/ Few Perfect Stds., Which Covered Only 8 HAPs *New Approach = Technology-Based Stds., Emission Reductions For 188 HAPs That Apply To “Major” & “Area OR Minor” Sources Of HAPs --- See Link To List Of 1990 CAAA HAPS* & Defn. Of VOC* = I.D.’ed @ End Of Presentation
Clean Air Act Primer Con't. • Title III (HAPs) Cont.: *HAP Emission Source: “Major” Stationary Source = Contiguous Area, Common Control, W/ > 10 TPY Single HAP OR 25 TPY Aggregate HAP --- “Area” Source Is One That Is Not Major (Must Include Fugitive) *MACT: Max. Achievable Control Tech. --- New Sources = Meet Best Controlled Similar Source --- Existing Sources = Ave. 5 Best (>30 Sites) OR Ave. Best 12% (<30)

Air Permitting & Compliance Construction Permitting • When Required? “Allowable Emissions” Increase/Decrease OR When Modify Process &/Or Control Equipment (Even “Like Kind” Replacement) = Not One Size Fits All! • Proposed Changes That Increase “Potential Emissions” By The Following (PSD Sig.): *PM @ 25 TPY Or >, PM-10 @ 15 TPY Or >, SOx, NOx, OR VOC @ 40 TPY Or >, CO @ 50 TPY Or >, Pb @ 0.6TPY Or >, Single HAP @ 2.5 TPY/Combined HAPs @ 10 TPY Or >
Construction Permitting Con't. • ”Allowable Emissions” = Emissions Rate Of Stationary Source Calc. Using Max. Rated Capacity Of Source (Unless Fed. Enforceable Limit Applies) AND Most Stringent Of NSPS, NESHAP, SIP, OR Existing Permit Condition(s) • Must Quantify Past Actual To Future Potential = NOT Potential To Potential, etc. • Must I.D. Whether NESHAP Applicable (“Major” Source 10/25 TPY PTE) W/ HAP Increase Of 2.5/10 TPY PTE Proposed
Construction Permitting Con't. • Many Proposed Mods. Involving HAPs Require Some Form Of BACT Analysis = BACT Is Analysis To I.D. Max. Degree Of Emission Reduction Achievable Considering Energy, Env., & Economic Impacts (Other Than Costs) --- Typically $3K To $4K/Ton Pollutant Removed Is Cut Off --- Must @ Least Be As Stringent As NSPS Or NESHAP --- BACT Is An Interim Step Towards MACT/NESHAPS Scheduled For Future But Have Yet To Be Promulgated ---See Proposed Rule ISSN 1521-9402 Link *
Construction Permitting Con't. • Proposed Rule ISSN 1521-9402 * Would Regulate HAP Emissions From Coatings/ Paints Applied To Misc. Metal Parts & Products --- It Would Only Apply To “Major” Sources Of HAPs (i.e., PTE >10 TPY Single HAP OR >25 TPY Of Combined HAPs) • Est. Reg. To Cost Metal Coating Industry $57MM/Year = Added Costs Incurred For “Control” Of Emissions (Capture-&-Reclaim Systems, More Costly Reformulated Subs., etc.) --- Powder Vs. Wet Painting Benefit!
Construction Permitting Con't. • Dispersion Modeling: Is Used To Demonstrate Compliance W/ NAAQS, Is Required For PSD, Is not Typically Performed For Minor Source Permits = Most Likely Not Required For Valmont Locations --- Background AAQ Monitoring • Non-Attainment Permitting: Offsets, LAER, All Other Sources In State Must Be In Compliance, Alternative Sites May Be Assessed To I.D.

Event In & Of Itself Must Be “Significant” Per PSD Thresholds • 8 HAPS Regulated By PSD = Asbestos, Beryllium, Mercury, Vinyl Chloride, Fluorides, Sulfuric Acid Mist, Hydrogen Sulfide & Total Reduced Sulfur
Construction Permitting Con't. • “Non-Attain. Area” - Area That Is Not Meeting NAAQS (i.e., CA Trip Reduction Reqs. If >30-40 People – Ozone/Smog, etc.) • “Attainment/Non-Attainment” Status Are On A Pollutant By Pollutant Basis • Overall Reduction Of 10% To 50% Req. = Can Be Costly & Prevent New Industry From Entering Or Existing Industry From Expanding Operations In A Particular Area • Ultimately, The NAAQS Would Be Achieved Over Time
Air Permitting & Compliance Operations Permitting • When Is An Operating Permit Required? *These Are Generally State Specific Req. Based From 40 CFR Part 70 • Various Permit Types W/ Assoc. Req. Exist *Class I Or Title V Major = >100 TPY (PTE & Actual) PM/TSP, PM-10, SOx, NOx, & CO; Pb >5 TPY; HAP (Single) >10 TPY; & HAP (Combo) >25 TPY *Class II Syn. Minor, Voluntary, OR FESOP = PTE > “Major Source” & Actuals < “Major”
Operations Permitting Con't. *Class II Minor Or Small Source Permit = PTE < “Major Source” W/ Actuals <50% “Major Source” Thresholds OR < “Significant Increase Thresholds” By PSD/Pre-Const. Permit Thresholds *VOC General Permit Alternative In Some States = Actuals Remain < Class I VOC/HAP *No Permit Req. = When PTE & Actuals Either Under “Major Source” Thresholds OR Both Are < “Sig.

Air Permitting & Compliance Chemical Accident Prevention (RMP) • Risk Mgt. Planning (RMP) = Do Not Believe Too Great Impact To Valmont But Need To Be Aware Of Reqs. --- For Example, Propane “Stayed” @ Present, HCl 37% Conc. & > @ 15,000 lbs, & Fuming H2SO4 @ 10,000 lbs are reg. • List Each Of 66 Flammable & 77 Toxic Substances That Require Planning If Trip Respective Thresholds (i.e., 10,000 Lbs For Flammables & 500 To 20,000 Lbs For Specific Toxic Compounds)
