How to use this
Section A is the foundation and must be current before anything else is useful. Sections B through D are permitting. Sections E and F are ongoing compliance. Sections G through I are enforcement response. The single most consequential item is number 14 — a written applicability analysis completed before a project is a defense, and one reconstructed afterward is an admission that nobody looked.
SECTION A — THE FACILITY BASELINE
☐ 1. Determine the attainment designation for every criteria pollutant for this location — 42 U.S.C. § 7407 — and the nonattainment classification where applicable — 42 U.S.C. § 7511.
☐ 2. Identify the state implementation plan provisions that apply — 42 U.S.C. § 7410, 40 C.F.R. Part 51, 40 C.F.R. Part 52. Old plan provisions are federally enforceable.
☐ 3. Build a current emissions inventory by unit: equipment, capacity, fuel, control devices, stack parameters, and emission factors used.
☐ 4. Compute potential to emit for every regulated pollutant, at maximum capacity, considering only federally enforceable limits.
☐ 5. Determine major source status separately for criteria pollutants and for hazardous air pollutants under 42 U.S.C. § 7412. The thresholds differ.
☐ 6. Identify every applicable performance standard — 42 U.S.C. § 7411, 40 C.F.R. Part 60 — and every hazardous pollutant standard — 40 C.F.R. Part 61, 40 C.F.R. Part 63.
☐ 7. Identify other applicable programs: risk management under 40 C.F.R. Part 68 · refrigerants under 40 C.F.R. Part 82 · greenhouse gas reporting under 40 C.F.R. Part 98 · product content under 40 C.F.R. Part 59.
☐ 8. Build a permit condition matrix: every condition, the record demonstrating compliance, the frequency, and the responsible person.
☐ 9. Inventory emergency generators with hour meters and a non-emergency operation policy.
☐ 10. Inventory synthetic minor limits and confirm a daily or monthly tracking system exists for each limiting parameter.
☐ 11. Confirm records retention meets the longest applicable period.
☐ 12. Identify the responsible official and confirm the delegation of authority is documented.
SECTION B — APPLICABILITY BEFORE A PROJECT
☐ 13. Trigger this section for any physical change or change in the method of operation — including replacements, upgrades, debottlenecking, fuel changes, and capacity increases.
☐ 14. ⚠️ Complete a written applicability analysis before construction begins. Include the emissions calculations, the baseline period selected and why, projected actual emissions, exclusions relied on, and the conclusion.
☐ 15. Determine whether the change is routine maintenance, repair, and replacement — and document the basis, including cost relative to replacement, frequency in the industry, purpose, and effect.
☐ 16. Compute the increase on the basis the applicable program uses. A falling hourly rate does not resolve an annual-tonnage inquiry — Environmental Defense v. Duke Energy Corp..
☐ 17. Evaluate netting against contemporaneous increases and decreases, and document the contemporaneous period used.
☐ 18. Evaluate any demand growth exclusion, with support.
☐ 19. If review is triggered in an attainment area, plan for 42 U.S.C. § 7475: control technology analysis, air quality analysis, monitoring, and public participation.
☐ 20. If review is triggered in a nonattainment area, plan for 42 U.S.C. § 7503: lowest achievable emission rate, offsets, statewide compliance certification, and an alternatives analysis.
☐ 21. Price offsets before pricing the project. In a severely classified area they can determine viability.
☐ 22. If concluding that review is not triggered based on a projection, establish the post-project tracking and reporting system the rules require.
SECTION C — PRECONSTRUCTION PERMIT APPLICATION
☐ 23. Assemble a precise equipment description: manufacturer, model, rated capacity, fuel, controls, stack parameters.
☐ 24. Prepare emissions calculations for every regulated pollutant with stated assumptions and sources.
☐ 25. Request a pre-application meeting. Ask what the agency expects, what modeling it wants, and which control technologies it considers available for this source category.
☐ 26. Conduct the control technology analysis in sequence: identify all available technologies · eliminate technically infeasible options with technical support · rank by effectiveness · evaluate energy, environmental, and economic impacts · select.
☐ 27. ⚠️ Do not eliminate an option as infeasible without support. This is the most common deficiency and the most common ground of challenge.
☐ 28. Agree the modeling protocol with the agency before running the model.
☐ 29. Address the additional impacts analysis — soils, vegetation, visibility, and growth.
☐ 30. File a complete application. The substantive clock does not start until completeness is determined.
☐ 31. Prepare for public comment: publish the application, consider an informal meeting, and anticipate objections on cumulative impacts, odor, and traffic.
☐ 32. Calendar the state administrative appeal deadline the day the permit issues.
☐ 33. Confirm local zoning approval separately. An air permit does not authorize a use that zoning prohibits.
SECTION D — THE OPERATING PERMIT
☐ 34. Determine whether an operating permit is required — 42 U.S.C. § 7661a, 40 C.F.R. Part 70, or the federal program at 40 C.F.R. Part 71.
☐ 35. Consider whether a synthetic minor permit is preferable, and model the operational constraint honestly before accepting limits.
☐ 36. In the application, identify every applicable requirement completely. The permit shield extends only to requirements identified or specifically determined not to apply.
☐ 37. Propose monitoring that is sufficient to assure compliance but that the facility can actually sustain. Over-promising monitoring creates deviations.
☐ 38. Confirm permit content requirements are addressed — 42 U.S.C. § 7661c.
☐ 39. Review the draft permit condition by condition against the matrix from item 8, and comment on anything unworkable before issuance.
☐ 40. Confirm the renewal timeline and calendar the application deadline years in advance.
☐ 41. Understand that federal petitions can reopen an issued permit.
☐ 42. Track permit modifications — administrative, minor, and significant — and use the correct route for each change.
SECTION E — MONITORING AND RECORDKEEPING
☐ 43. Build a monitoring plan covering every parameter the permit requires, with frequency, method, and record location.
☐ 44. Implement quality assurance: calibration schedules, certification, and drift checks.
☐ 45. Track data availability. ⚠️ Monitor downtime below a required availability threshold is itself a deviation.
☐ 46. Maintain parametric monitoring records where a surrogate demonstrates control device operation.
☐ 47. Calendar stack tests and submit protocols for approval in advance.
☐ 48. Maintain generator hour logs and a documented non-emergency operation policy.
☐ 49. Maintain coating, solvent, and material usage records supporting emissions calculations.
☐ 50. Maintain refrigerant service, leak rate, and technician certification records — 40 C.F.R. Part 82.
☐ 51. Maintain a complaint log with investigation and response documented. Odor complaints drive local enforcement even where emissions comply.
☐ 52. Confirm every record is retained for the longest applicable period and is retrievable.
SECTION F — DEVIATIONS AND CERTIFICATION
☐ 53. Maintain a deviation log capturing every departure from any permit term — including monitoring and recordkeeping terms, not just emission limits.
☐ 54. Report deviations on the schedule the permit requires.
☐ 55. Document corrective action for each deviation, including root cause.
☐ 56. Reconcile the deviation log, the semiannual reports, and the draft certification quarterly. Discrepancies found in December are much harder to fix than discrepancies found in April.
☐ 57. Have the responsible official read the permit before signing the annual certification.
☐ 58. For each condition, determine continuous or intermittent compliance, and if intermittent, identify the periods.
☐ 59. Confirm the signer holds documented delegated authority.
☐ 60. ⚠️ A knowingly false certification can be charged criminally under 42 U.S.C. § 7413. Build the record that supports the signature.
SECTION G — RESPONDING TO AN INFORMATION REQUEST
☐ 61. Treat a request under 42 U.S.C. § 7414 as compulsory and penalty-backed, not as correspondence.
☐ 62. Issue a document hold immediately covering everything within scope.
☐ 63. Assemble a team: environmental, operations, records, and counsel.
☐ 64. Confirm the scope in writing and negotiate a realistic schedule with a credible plan.
☐ 65. Identify every custodian and system: data historians, maintenance systems, laboratory records, and email.
☐ 66. Produce completely. An omission later supplemented is worse than a slower complete response.
☐ 67. Log everything produced with dates.
☐ 68. Assess privilege realistically — required records and monitoring data are generally not privileged.
☐ 69. Run your own analysis of the same facts in parallel. The request reveals the agency's theory.
SECTION H — RESPONDING TO A NOTICE OF VIOLATION
☐ 70. Calendar the response deadline and request a meeting.
☐ 71. Verify each alleged violation against primary records, not summaries.
☐ 72. Identify factual errors and misread permit conditions, with citations.
☐ 73. Document corrective action already taken, with dates.
☐ 74. ⚠️ Complete any delayed compliance action now. Economic benefit is calculated, not negotiated, and it stops accruing when the action is complete.
☐ 75. Compute the likely economic benefit yourself so you can discuss it credibly.
☐ 76. Assemble gravity mitigation: self-disclosure, cooperation, prompt correction, compliance history, and any environmental benefit already achieved.
☐ 77. Evaluate any affirmative defense available under the applicable plan provision, such as a malfunction defense, and confirm its notice and documentation prerequisites were met.
☐ 78. Consider supplemental environmental projects where available.
☐ 79. Negotiate the injunctive relief hardest. It typically costs far more than the penalty.
☐ 80. Review stipulated penalty provisions for achievability before agreeing to milestones.
☐ 81. Assess criminal exposure where any falsification of data or reports may be involved, and change counsel structure accordingly.
SECTION I — CITIZEN SUIT NOTICE
☐ 82. Verify every alleged violation against your own records — most notices are built from self-reported data.
☐ 83. Determine whether each alleged violation was reported and whether corrective action was documented.
☐ 84. Determine whether the agency is diligently prosecuting the same conduct, which can bar the suit.
☐ 85. Consider approaching the agency about a resolution that addresses the same conduct.
☐ 86. Evaluate standing and the ongoing violation requirement.
☐ 87. Account for attorney's fees exposure under 42 U.S.C. § 7604 in any settlement analysis.
☐ 88. Use the sixty-day period to complete corrective action and document it.
SECTION J — ANNUAL SELF-AUDIT
☐ 89. Re-verify the emissions inventory against production and purchase records.
☐ 90. Re-verify potential to emit after any equipment change.
☐ 91. Test every synthetic minor limit against primary records for the last five years.
☐ 92. Confirm every physical change in the last decade has a contemporaneous applicability analysis on file.
☐ 93. Audit monitoring data availability and calibration records.
☐ 94. Reconcile the deviation log to reports and certifications for the last three years.
☐ 95. Verify generator hours against the non-emergency operation limits.
☐ 96. Verify refrigerant records and leak repair timelines.
☐ 97. Check whether the designation or classification of the area has changed.
☐ 98. Check for pending rules affecting this source category.
☐ 99. Where problems are found: correct promptly, document the correction, and evaluate voluntary disclosure — prompt correction is the largest gravity mitigator available.
SECTION K — ACQUISITION DILIGENCE
☐ 100. Obtain the permit and every amendment.
☐ 101. Obtain five years of semiannual reports, annual certifications, deviation reports, and stack test results.
☐ 102. Obtain all agency correspondence, including any information requests.
☐ 103. Verify the emissions inventory against production data.
☐ 104. ⚠️ Verify that every physical change in the last decade was analyzed for applicability, with contemporaneous documentation. Undocumented modifications are the most common material finding and they travel with the facility.
☐ 105. Verify synthetic minor compliance from primary records.
☐ 106. Confirm the area designation and whether classification has changed.
☐ 107. Identify pending rules that will impose new requirements on the source category.
☐ 108. Quantify any identified exposure and allocate it through indemnity, escrow, or price adjustment.
☐ 109. Confirm local zoning and any nuisance or complaint history.
☐ 110. Confirm refrigerant, tank, and generator compliance — the small items that produce most findings.
SECTION L — SMALL AND MEDIUM FACILITY PROGRAM
Most regulated facilities are not refineries. This is the short program that prevents the overwhelming majority of violations at a fabricator, printer, food processor, hospital, university, data center, quarry, asphalt plant, or grain handler.
☐ 111. Know your permit type — synthetic minor, minor, general permit, or Title V — and keep a copy where operations staff can find it.
☐ 112. Identify the one or two parameters that keep you under a threshold, and track them monthly at minimum, from primary records.
☐ 113. Emergency generators: install hour meters, log hours monthly, and adopt a written policy prohibiting non-emergency operation except as the applicable standard allows. ⚠️ Demand response and peak shaving frequently exceed what the standard permits.
☐ 114. Boilers and process heaters: confirm which standard applies by size, fuel, and major or area source status, and calendar tune-ups and energy assessments.
☐ 115. Coating and printing: retain purchase records and technical data sheets for every coating, thinner, and cleanup solvent, and compute monthly usage.
☐ 116. Degreasing: confirm equipment requirements and operating practices, and post them at the unit.
☐ 117. Refrigeration: inventory equipment by refrigerant type and charge size, compute leak rates, retain service records, and confirm technician certification — 40 C.F.R. Part 82.
☐ 118. Storage tanks: confirm vapor control requirements by size and vapor pressure.
☐ 119. Fugitive dust: implement and document control measures for material handling and unpaved surfaces.
☐ 120. Products used in operations: confirm content limits under 40 C.F.R. Part 59 where applicable.
☐ 121. File reports on time. Late filing of an otherwise clean report is a violation that costs nothing to avoid.
☐ 122. Assign one owner for the whole program, with a backup, and a calendar.
SECTION M — COMMUNITY ENGAGEMENT
☐ 123. Publish the permit application and supporting analysis proactively.
☐ 124. Hold an informal meeting before the formal hearing. It is inexpensive and materially reduces opposition.
☐ 125. Offer accessible monitoring information where feasible.
☐ 126. Adopt a complaint response protocol: a phone number that is answered, a logged response within twenty-four hours, an investigation, and a written closeout.
☐ 127. Anticipate the recurring themes: cumulative exposure, odor, truck traffic, and monitoring transparency.
☐ 128. Recognize that odor is frequently unaddressed by any emission limit — a fully compliant facility can still face nuisance claims and local enforcement.
☐ 129. Understand that complaint logs are discoverable and are read.
SECTION N — QUICK REFERENCE
☐ 130. Designation decides everything — 42 U.S.C. § 7407. ☐ 131. Potential to emit is capacity, not actual emissions. ☐ 132. Write the applicability analysis before the project, not after. ☐ 133. A falling hourly rate is not a complete answer — Environmental Defense v. Duke Energy Corp.. ☐ 134. Price offsets before pricing the project in nonattainment areas — 42 U.S.C. § 7503. ☐ 135. The permit shield is only as broad as the applicability analysis in the application. ☐ 136. Monitor downtime is a deviation. ☐ 137. Reconcile the deviation log quarterly, not annually. ☐ 138. Economic benefit stops accruing when the delayed action is complete — 42 U.S.C. § 7420. ☐ 139. Falsifying data or reports is what turns a civil matter criminal — 42 U.S.C. § 7413. ☐ 140. Citizen suits carry attorney's fees — 42 U.S.C. § 7604. ☐ 141. A state permit is not the end of the analysis — Alaska Dep't of Environmental Conservation v. EPA. ☐ 142. The violation is frequently the missing record, and it is counted per day.
SECTION O — THE APPLICABILITY MEMORANDUM
Every project should generate one document, written before construction, that a regulator could read years later. This is its structure.
☐ 143. Project description. What is being installed, removed, replaced, or changed, in physical terms, with drawings or specifications attached.
☐ 144. Purpose. Why the project is being done — reliability, capacity, efficiency, product change, or regulatory compliance. Purpose matters to the routine maintenance analysis and to the demand growth exclusion.
☐ 145. Affected emission units, identified by permit unit number.
☐ 146. Baseline actual emissions, with the lookback period selected, the reason for selecting it, and the underlying data — operating hours, throughput, fuel use, and emission factors.
☐ 147. Projected actual emissions after the project, with the assumptions stated and the basis for each.
☐ 148. Excludable increases, if any, attributable to demand growth that could have been accommodated before the project, with support.
☐ 149. Netting analysis, if used: contemporaneous increases and decreases, the period, and the enforceability of each decrease.
☐ 150. Comparison to significance thresholds for each pollutant, showing the arithmetic.
☐ 151. Conclusion — review triggered or not, and for which pollutants.
☐ 152. Post-project obligations, if the conclusion rests on a projection: what will be tracked, for how long, and when reports are due.
☐ 153. Preparer, reviewer, and date. ⚠️ A memorandum dated after construction began is worth very little.
SECTION P — WHAT TO DO IN THE FIRST WEEK OF A PROBLEM
☐ 154. Stop the noncompliant activity if it is ongoing and can be stopped safely, and document the decision and the time.
☐ 155. Preserve everything — issue a hold covering monitoring data, maintenance records, operating logs, email, and any draft analyses.
☐ 156. Determine the reporting obligation. Many permits require prompt deviation reporting within twenty-four to seventy-two hours, separate from the semiannual report.
☐ 157. Report on time even if the facts are incomplete, and supplement.
☐ 158. Establish the timeline — when the condition began, when it was discovered, and by whom.
☐ 159. Quantify the emissions consequence, if any, using available data.
☐ 160. Identify the root cause, distinguishing equipment failure, procedure failure, and training failure.
☐ 161. Implement corrective action and document completion dates.
☐ 162. Assess whether the annual certification already filed was affected, and whether an amendment is appropriate.
☐ 163. Evaluate voluntary disclosure if the problem was found through a systematic audit and meets the applicable conditions.
☐ 164. Brief the responsible official personally. They will sign the next certification, and they should not learn about this from the report.
☐ 165. Fix the system, not the instance — the tracking gap, the missing procedure, or the unassigned responsibility that allowed it.
