Workflow

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 reconnaissance data, regulatory database results, historical sources, and interview notes to classify recognized environmental conditions and establish all appropriate inquiries for CERCLA liability protection.

Drafting Phase I Environmental Site Assessments is one of the most time-intensive tasks in environmental consulting. Each report requires synthesizing dozens of data sources—regulatory databases, historical records, site observations, interviews, and questionnaires—into a structured document that must comply with the detailed requirements of ASTM E1527-21. For firms handling multiple assessments simultaneously, the manual drafting burden creates bottlenecks, delays transactions, and increases the risk of inconsistencies or omissions.

CaseMark automates the composition of Phase I ESA reports by ingesting your source materials and structuring them into a fully compliant ASTM E1527-21 report draft. The AI classifies RECs, CRECs, and HRECs, flags data gaps, and generates all required sections—from executive summary through appendices—so Environmental Professionals can focus their expertise on analysis and professional judgment rather than document assembly.

How it works

  1. 1. Upload site reconnaissance data, regulatory database results, historical sources, and interview notes

  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 from days to minutes while maintaining ASTM E1527-21 compliance

Ensure consistent REC, CREC, and HREC classification with documented rationale across every report

Automatically identify and flag data gaps so Environmental Professionals can address deficiencies before finalization

Streamline environmental due diligence workflows for high-volume property transactions and lending portfolios

Questions

Does the output comply with the current ASTM E1527-21 standard?

Yes. CaseMark structures every Phase I ESA report to meet ASTM E1527-21, which became the EPA-recognized standard for all appropriate inquiries on February 13, 2023. The prior E1527-13 standard is no longer compliant, and CaseMark ensures your report reflects the current requirements.

How does CaseMark classify RECs, CRECs, and HRECs?

CaseMark analyzes your uploaded site data, regulatory database results, and historical sources to identify and classify Recognized Environmental Conditions (RECs), Controlled RECs (CRECs), and Historical RECs (HRECs) according to ASTM E1527-21 definitions. Each classification includes supporting rationale for environmental professional review.

Can this replace the work of a qualified Environmental Professional?

CaseMark is designed to accelerate the drafting process, not replace professional judgment. The output serves as a comprehensive draft that a qualified Environmental Professional (as defined under 40 CFR § 312.10) should review, verify, and sign. It dramatically reduces the time spent on report composition so EPs can focus on analysis and conclusions.

What if I have data gaps in my source materials?

CaseMark automatically identifies and flags data gaps per ASTM E1527-21 requirements. Missing prerequisite information—such as incomplete owner questionnaires or inaccessible areas during site reconnaissance—is documented in a dedicated Data Gaps section with an assessment of their significance to the findings.

Can I use this for lending and acquisition transactions?

Absolutely. CaseMark supports Phase I ESA drafting for acquisitions, lending, corporate compliance, and other transaction purposes. The report includes the appropriate CERCLA liability protection language and all appropriate inquiries documentation needed for each use case.

How does CaseMark handle prior Phase I or Phase II reports?

You can upload prior environmental reports as supplemental inputs. CaseMark will incorporate relevant findings, note any changes in conditions since previous assessments, and ensure the new report addresses updates required under the current ASTM E1527-21 standard.
