Active CDPS Permits and Certifications

CDPHE's public active-permits workbook reports permittee and facility identity, CDPS permit identifier, status, sector and permit type, issue, effective, expiration and termination dates, receiving-water and outfall context, and compliance-tracking status. The permittee and facility fields pin the organisation association and the registry's current permit standing; compliance-tracking status is not itself a finding that the permittee is compliant.

BWPC Active NPDES Permits

Nevada NDEP's public ArcGIS source is explicitly filtered to Major or Minor NPDES records with PERMITSTAT='PRMTISS' and reports business and facility identity and address, permit number, category, type and status, effective and expiration dates, and compliance-labelled fields. It establishes an organisation-associated currently issued permit when the target matches the published business identity and facility association.

CIWQS NPDES Report Export

California Water Boards publishes an unauthenticated statewide NPDES export linking active individually designated permit records to discharger and facility identities and addresses, NPDES and regulatory-measure identifiers, regulatory status and type, programme and order details, and effective, expiration and termination dates. This establishes an organisation-associated permit and its reported current regulatory standing; blanket general-permit enrollee rows remain outside the documented scope.

NPDES Current Permits

Iowa DNR's public current-permits workbook for individual NPDES and state-operation authorisations reports owner and facility identity, Iowa permit and EPA identifiers, permit type and classification, expiration date, facility location, treatment, design flow and operator requirements. Owner and facility identity pin the organisation-associated authorisation, while inclusion in the current listing and the expiration date report its standing; general-permit authorisations are excluded.

NPDES Permits

WVDEP's standing public ArcGIS layer, scoped by the verified integration to Industrial and Sewage NPDES permit types, reports active and historical permit identifiers and types, facility and responsible-party identity, lifecycle dates and status, coordinates, flow and receiving-stream context. Use it for a named organisation only where RESP_ID or RESP_NAME and the facility record demonstrably resolve to that organisation.

NPDES Wastewater Discharge Permits

North Carolina DEQ's public queryable statewide layer reports OWNER and FACILITY together with permit number, type and status, original issue, effective and expiration dates, facility active flag and facility status. It establishes an organisation-associated NPDES permit and the current standing reported by the registry when the named owner explicitly resolves to the target organisation.

TDEC APC Permits

TDEC's pre-verified statewide Air Pollution Control permit source is filtered to currently active, issued permits and reduced to one row per Facility ID, retaining the most recently issued active permit. Its schema reports Permittee Name, Facility ID, permit number and type, raw status, issue date, and expiration date. When Permittee Name resolves to the target organisation, these fields establish the organisation–facility association and pin the Tennessee APC permit's reported current standing. This claim is limited to APC permit standing and does not imply broader compliance performance.

WQSIS Active NPDES Facilities

Oregon DEQ's anonymous active-NPDES query returns facility identity and address, EPA and permit identifiers, programme classification, and active status. Linked public Facility Details identify the legal organisation and report permit type, start and expiration dates, active-permit flag, last action date and description; the permit tracker reports a dated current status. Use the answer only when the target matches the published Legal Name, not merely a similar facility label.

Air Facility Systems

New Hampshire DES's standing public Air Facility Systems layer returns facility name and address, AFS identifier, facility class, raw facility status, and permit type through a queryable and downloadable ArcGIS service. When the published facility identity demonstrably resolves to the named organisation, those fields report its New Hampshire air-programme and permit standing as of the registry search date. LAST_INSP supplies only the latest inspection date and is not evidence of noncompliance, a violation, or affirmative compliance.

Air Permitted Facilities

Nebraska DWEE's public, unauthenticated Permitted Facilities interface labels its results 'Facility Information and Active Permits,' permits search by facility name, facility address, programme and permit type, and offers download. The AIR response identifies the Clean Air Act programme and reports facility or operating-company name and address, permit name and type, application number, and issue, expiration and extension dates. It supports current organisation-associated air-permit standing only when the published facilityName is the target operating company or another documented exact organisation–facility relationship establishes attribution; a similar facility label alone is insufficient. Reconciliation should use the permit-level upstream response rather than the integration's one-representative-row-per-facility output.

Air Permitted Facilities

Wisconsin DNR's public WARP All Facilities layer and Air Management Data Viewer cover active air-permitted facilities and return facility identity, an end-date field, EPA class, and Part 70, PSD, and nonattainment-NSR programme flags. For a named organisation, use the record only when the published facility identity and a documented organisation–facility match resolve the target; the active roster and programme flags then establish reported Wisconsin air-permit/programme standing as of the viewer update and search date. The flags do not establish that the organisation is compliant or violation-free.

ICIS NPDES Facilities

EPA's public ECHO CWA Facility Search REST service accepts arbitrary facility names, addresses, FRS registry identifiers and NPDES permit identifiers. Its documented response reports facility and registry identity, SourceID, permit name and type, issuing agency, permit status, issue, effective, expiration and termination dates, current compliance status, significant-noncompliance status and 13-quarter compliance history. Attribute the result to an organisation only where an exact returned identifier and documented organisation-facility relationship establish the association; facility-name similarity alone is insufficient.

PFAS DMR

For the PFAS-monitoring subset, EPA's public layer reports NPDES permit number, permit type, current permit status, facility and FRS identity, and whether a PFAS parameter has an effluent limit. Use it only where those identifiers establish a documented facility-to-selected-organisation association, and retain the raw current-permit status and search date. A permit status or effluent-limit indicator is not affirmative evidence of compliance, noncompliance, or a violation.

PFAS Industry Sectors

For facilities in the delivered Industry Sectors universe, EPA publishes facility and programme identifiers, EPA programme flags, CAA, CWA, and RCRA permit types, active status, facility compliance status, and SDWA compliance and significant-noncompliance fields. These directly evidence officially associated environmental programmes, permit types, and reported standing when the facility-to-organisation match is demonstrable. Pin retrieval date, preserve the delivered 714-facility universe, and do not infer actual PFAS handling, release, contamination, or liability from sector inclusion.

Vermont DEC's public facility search describes its records as current Air Pollution Control Permits and returns current facility or company name, former names, operating status, current application number, and issued-permit and technical-analysis document identifiers. When the published company/facility identity exactly resolves to the named organisation, the current permit record and operating status establish reported Vermont air-permit standing as of the search date. They do not by themselves establish compliance, violations, or a dated permit term.

Air Facilities

MassDEP's standing public statewide layer is expressly limited to open air facilities subject to Source Registration and/or greenhouse-gas reporting; its metadata says major facilities have operating permits while minor facilities remain subject to reporting. FAC_ID and FAC_NAME identify the facility, GHG_REPORT, NESHAPS, and NSPS report regulated-programme applicability, and CLASS, CLASS_DESC, and MAJ_MIN report fee/source class and major/minor operating-permit category. Use this link only when FAC_NAME demonstrably resolves to the named organisation, retain the layer vintage and search date, and do not interpret the layer as supplying a permit number, permit term, or affirmative compliant/noncompliant finding.

All Active Air Pollution Emitting Facilities

CDPHE Air Pollution Control Division's public ArcGIS layer is an official statewide roster of All Active Air Pollution Emitting Facilities, keyed by AIRS ID and publishing facility name, point location, and data-publication date. The campaign-verified product scope identifies these as facilities holding an active Air Pollutant Emission Notice; because an APEN is a required regulatory emissions notice rather than an air permit, active roster membership supports only the regulated-programme-standing half of this Sub-concern. Attribute it to a named organisation only after an exact facility/organisation match; do not infer permit issuance, emissions quantity, compliance, or violation status.
