Regulating Industrial Water Pollution Under the Clean Water Act of 1972: Progress and Challenges
The Clean Water Act of 1972 established robust regulations to control industrial water pollution in the U.S., with the ambitious goal of zero pollution discharge by 1985. Key measures include a construction grants program and technology-based regulations through the National Pollutant Discharge Elimination System (NPDES). The EPA sets federal effluent guidelines, while states enforce permits targeting pollutants like biochemical oxygen demand (BOD) and total suspended solids (TSS). Despite some successes, significant noncompliance issues remain, alongside challenges in reducing priority pollutant discharges.

Presentation Transcript
Command and Control Regulation in Action Regulating Industrial Water Pollution in the US
Clean Water Act of 1972 • Sets national goals as zero-discharge of pollution by 1985 • 2 Main Policy Tools • Construction grants program $$ • Technology based regulations for discharge of water pollution from point sources
National Pollutant Discharge Elimination System • EPA- establishes Federal Effluent Guidelines • States– write,monitoring, and enforce NPEDS permits • Main Targets • Biochemical oxygen demand (BOD) • total suspended solids (TSS) • 15 pollutants of concerns, (metals i.e. arsenic and mercury)
POTW • Tech Regulation • Primary treatment (skimming, screening, settling) 65% • Secondary treatment - 80-90% • Criteria on uses for sludge • ensuring effective operation and maintenance
Direct Discharges from Industrial Plants • EPA guidelines for 30 designated industries • best practicable technology by 1977 • Best Available Tech by 1983 • New Source Performance Standards
Complexity • Dairy Standards • Different standards for subcategories • Acceptable pollutant discharge rates vary • BOD 30 day standard for large facilities Butter .55kg per 1000 kg of BOD input; Cottage cheese 2.6, Ice bream 1.84, Condensed Milk 1.38, Dry Milk .65 • Separate limits for one day maximum discharge, 30 day average, for small and large facilities.
Indirect discharges from industrial plant • Industrial plants to POTW • Pretreatment guidelines
Rulemaking Process • Information Requirements • Writing of direct discharge standards • How to operationalize best, practicable, economically achievable • Need information on production techniques, location, waste products, and waste treatment tech • heterogeneity --360 industrial subcategories among first 30 industries requiring effluent guidelines • separate BPT, BAT, NSPS< and pretreatment regulations
Rulemaking Process • Role of consulting firms • Proposed standards, industry comment • 250 lawsuits
Regulatory Output • BPT - 1 year • BAT standards – 1/3rd done by 1995 • Zero Discharge – still waiting
Abatement Costs • Big variation in incremental costs • Estimate of costs > than actual
Compliance • Assumption- 97% reduction in discharge of priority pollutants • Compliance – mixed • 6% of major direct dischargers -significant noncompliance • % of US served by POTWs increases from 42% to 74% • POTW pretreatment- 54% of significant indutstrial users were in significant noncompliance (1992)
But is the water cleaner? • Some big successes- Potomac, Delaware • Lack of data,
Perverse Incentives • Expansion of POTW Construction Grants Program • shift from direct discharge towards indirect discharge
