Start acquisition due diligence before the transfer date
For a proposed UPM-related Arizona pulp-and-paper acquisition, use the actual site, seller, operator and permit inventory. This is a due-diligence framework, not evidence that a particular transaction occurred. Do not assume that four permits automatically activate on closing, that every authorization transfers in the same way, or that the new operator receives a universal post-closing grace period.
Read122.61 as a conditional permit-transfer rule
40 CFR122.61(a) provides transfer through modification, revocation/reissuance or a qualifying minor modification. Paragraph(b) offers an automatic-transfer alternative where the current permittee notifies the Director at least30days before the proposed transfer, includes a written agreement fixing the date for responsibility, coverage and liability, and the Director does not give the specified notice of intent to modify or revoke/reissue. It is not a requirement to file a2A/2S name change within30days after closing, and it does not state the former automatic-termination rule.
For an actual AZPDES authorization, confirm the applicable Arizona transfer provisions and the issued permit with ADEQ before scheduling the transfer. A legal-entity name change, ownership transfer and process/flow modification are different facts. Assign each notice to the party required to submit it; retain the agreement, submission evidence and agency response.
| Authorization or record | Evidence to obtain | Transaction deliverable |
|---|---|---|
| AZPDES and relevant outfalls | Current permit, transfer path, advance notices, agency instructions and outstanding orders | Responsible parties, actual dates and evidence of continued valid coverage |
| Individual APP where applicable | ADEQ amendment/transfer requirements, technical conditions and financial assurance | Accepted transfer/amendment documentation, not presumed mandatory reissuance |
| Industrial stormwater coverage | Actual general permit and operator/change/termination conditions | Site-specific coverage actions without an invented90-day deadline |
| POTW connection and reuse | Actual sewer authority and control mechanism; any intended reuse authorization | Written decision on transfer/new approval, limits, reporting and intended use |
Check APP separately from AZPDES
ADEQ’s current Individual APP guidance expressly describes ownership transfer as an Other Amendment and lists notice, transfer agreement, acceptance of permit terms, financial assurance and fees among the requirements. It does not support the former claim that every ownership change must be a new permit rather than a transfer. Determine whether proposed construction, flow or technology changes separately require another amendment. Use actual programme instructions; do not transplant a universal180-day clock.
Turn the permit inventory into a treatment RFQ
Map the mill’s real process, cleaning, cooling and stormwater streams and obtain representative flows, loads and existing performance records. Screen any industry-category applicability and actual permit/connection conditions. Compare source segregation, solids removal, biological treatment and any polishing against measured needs. A DAF system or MBR is an option to test, not proof of meeting every reuse class. Define dissolved-contaminant targets, concentrate and sludge destinations and safe upset handling.
Require a supplier mass balance, trial report, capacity/quality acceptance conditions, utilities, consumables, maintenance and residual costs on the same scope. The deal team owns the permit inventory and schedule; the qualified environmental adviser confirms applicability; the operator supplies representative data; the buyer’s engineer and supplier agree documented acceptance. Preserve historical noncompliance and liabilities for qualified review instead of asserting that a name change either cancels or automatically transfers every liability.
Frequently asked questions
Is the federal30-day notice after closing?
No. The automatic-transfer alternative in122.61(b) uses notice by the current permittee at least30days before the proposed transfer and has additional conditions.
Must every APP be reissued on acquisition?
No blanket reissuance rule is established. ADEQ describes an ownership-transfer amendment process; actual permit and proposed operational changes must be assessed separately.
What should stop an equipment purchase?
Missing discharge coverage, unresolved transfer actions, unknown written limits or an untested feed specification are reasons to resolve the design basis before fixing a performance guarantee.
