EPA Details
What It Is
EPA standards are a family of legally binding regulatory requirements implementing major U.S. environmental statutes, primarily Clean Air Act (CAA), Clean Water Act (CWA), and Resource Conservation and Recovery Act (RCRA). Codified in Title 40 CFR, they form a multi-layered framework for protecting human health and the environment. The core approach blends health-based ambient standards (e.g., NAAQS) with technology-based controls (e.g., MACT, effluent guidelines) via risk management.
Key Components
- Statutory mandates, 40 CFR regulations, numeric/narrative limits.
- Permitting (NPDES, Title V, RCRA), monitoring/reporting, enforcement.
- Evidence regimes with approved methods (40 CFR Part 136), QA/QC. Built on federal-state implementation; no single certification but site-specific compliance via audits/inspections.
Why Organizations Use It
Mandated for regulated entities to avoid civil/criminal penalties, operational shutdowns. Manages enforcement risks, secures permits for operations. Enhances ESG reputation via transparency (ECHO, ICIS-NPDES), drives efficiency through pollution prevention.
Implementation Overview
Phased: gap analysis, regulatory mapping, controls/training deployment, digital monitoring, audits. Applies to industrial facilities nationwide; high complexity due to media/state variability. Ongoing via PDCA, docket tracking.
WCAG Details
What It Is
Web Content Accessibility Guidelines (WCAG) is a W3C recommendation and global technical standard for making web content accessible to people with disabilities. Its primary purpose is to provide testable success criteria ensuring content is perceivable, operable, understandable, and robust (POUR principles). Scope covers websites, apps, and digital documents technology-agnostically.
Key Components
- Four POUR principles with 13 guidelines and ~80 success criteria at A, AA, AAA levels.
- Normative success criteria; informative techniques, failures, and understanding docs.
- Conformance model requires full pages, complete processes, accessibility-supported tech, non-interference.
Why Organizations Use It
- Meets legal benchmarks (ADA, Section 508, EN 301 549, EAA).
- Reduces litigation risk, expands market reach (1B+ disabled users).
- Improves UX, SEO, conversions; builds stakeholder trust.
Implementation Overview
- Phased: policy, assessment, remediation, training, CI/CD integration, audits.
- Applies to all sizes/industries; AA common target.
- No formal certification; self-assess via audits, VPATs. (178 words)
