Overview

CaseMark's Phase I ESA skill drafts comprehensive environmental site assessment reports compliant with ASTM E1527-21 and 40 CFR Part 312. It analyzes site data, regulatory records, and historical sources to classify recognized environmental conditions and establish all appropriate inquiries for CERCLA liability protection. Environmental Professionals can produce thorough, standards-compliant reports in a fraction of the time traditionally required.

Drafting Phase I ESA reports is one of the most time-consuming tasks in environmental consulting. Each report requires meticulous organization of site data, regulatory records, historical sources, and interview findings into a standards-compliant document—often taking days of manual writing and formatting. With the transition to ASTM E1527-21, ensuring every report meets the latest AAI requirements adds another layer of complexity and risk.

CaseMark automates the heavy lifting of Phase I ESA report drafting by ingesting your site data, regulatory database results, and historical records, then producing a fully structured report aligned with ASTM E1527-21. The AI classifies environmental conditions, flags data gaps, and generates standards-compliant language—freeing Environmental Professionals to dedicate their expertise to site reconnaissance, professional judgment, and client advisory rather than manual document assembly.

How it works

  1. 1. Upload site reconnaissance data, regulatory database results, historical records, and questionnaire responses

  2. 2. AI analyzes all inputs against ASTM E1527-21 requirements and classifies environmental conditions

  3. 3. Review the drafted Phase I ESA report, REC classifications, and data gap analysis

  4. 4. Export the finalized report in your preferred format (DOCX, PDF)

Why teams use it

Reduce Phase I ESA report drafting time by up to 80%, allowing Environmental Professionals to focus on site work and professional judgment

Ensure consistent compliance with the current ASTM E1527-21 standard and AAI requirements across every report

Systematically identify and document data gaps, reducing the risk of omissions that could undermine liability protections

Produce well-organized REC, CREC, and HREC classifications with clear supporting rationale for clients and lenders

Questions

Does this produce a report compliant with the current ASTM E1527-21 standard?

Yes. CaseMark drafts Phase I ESA reports structured to meet ASTM E1527-21, which became the EPA-recognized standard for all appropriate inquiries on February 13, 2023. The prior E1527-13 standard lost AAI recognition in February 2024 and is no longer compliant.

Can CaseMark classify RECs, CRECs, and HRECs automatically?

CaseMark analyzes your site data, regulatory database results, and historical records to draft proposed REC, CREC, and HREC classifications with supporting rationale. The Environmental Professional should review and confirm all classifications before finalizing the report.

Does this replace the need for an Environmental Professional?

No. ASTM E1527-21 and 40 CFR Part 312 require that a qualified Environmental Professional oversee and sign the Phase I ESA. CaseMark accelerates the drafting process so EPs can focus on professional judgment, site reconnaissance, and quality review rather than manual report writing.

What data do I need to provide before generating a report?

CaseMark needs site identification details, reconnaissance observations, regulatory database search results, historical source documentation, interview notes, and owner/occupant questionnaire responses. The system will flag any missing items as data gaps in the final report.

Can I use this for lending transactions and CERCLA innocent landowner defense?

Absolutely. CaseMark structures the Phase I ESA to establish all appropriate inquiries under 40 CFR Part 312, which is essential for CERCLA liability protections including the innocent landowner defense, contiguous property owner defense, and bona fide prospective purchaser status.

How does CaseMark handle data gaps in the assessment?

CaseMark automatically identifies and documents data gaps per ASTM E1527-21 requirements, evaluates their significance to the assessment findings, and includes appropriate language regarding whether the gaps affect the ability to identify conditions indicative of releases or threatened releases.
