Conclusion

• Reporting, Compliance Schedules, & Documentation

NPDES Issues: Basement Backup Provisions

Sanitary Sewer Overflows

• Part II.B.2 (g)
• Language Utilized in Both Separate & Combined Permits

NPDES Issues: Basement Backup Provisions

Background & Implications

• Required by EPA/IDEM Enforcement Staff
• Identified in Recent Permits (1-2 months)
• Apparent liability issues
• Burden on POTW - Lateral vs. Sewer?
• Private property issues - Homeowner maintenance

NPDES Issues: Nutrient Limitations

NPDES Issues: Nutrients

USEPA National Nutrient Strategy

• Specific for waterbody type (e.g. rivers & streams, lakes & reservoirs, estuaries & coastal, and wetlands)
• Should include the following:
  Causal
  Total Nitrogen
  Total Phosphorous
  
  Early Response
  Chlorophyll a
  Turbidity

NPDES Issues: Nutrients

Criteria Development

• 2000 - EPA required all states to develop nutrient water quality standards
• Difficulty - N & P Concentration and Biotic Index Relationships
• States are in various stages of adopting criteria (IN - P Monitoring)
• Wisconsin may lead the way in EPA Region 5

NPDES Issues: Nutrients

Wisconsin categorizes receiving water P concentration limits by:

• Rivers - 100 ug/l
• Streams - 75 ug/l
• Stratified Reservoirs - 30 ug/l
• Non-Stratified Reservoirs - 40 ug/l
• "Two-Story" Fishery - 15 ug/l
• Lake Michigan - 7 ug/l
• Lake Superior - 5 ug/l

NPDES Issues: Antidegradation

Federal Clean Water Act requires states to develop rules to:

• Protect existing uses of waters
• Maintain existing water quality
• Provide a mechanism to include a public input process for evaluating any proposed deterioration of water quality from discharges

NPDES Issues: Antidegradation

Indiana Implications

• Currently applied to Great Lakes Basin
• Proposed rule to expand entire state
• IDEM responses are forthcoming
• Commissioner still intends to finalize in 2010

NPDES Issues: Pretreatment

Sewer Use Ordinances

Streamlining Revisions

• Best Management Practices (BMPs)
• Slug Control Discharge Requirements
• Repeat Sampling Authorization if violation is discovered
• Significant Noncompliance (SNC) Modifications

Stormwater: Rule 5

Effluent Limitations Guidelines

• Turbidity
  
  • Limit 280 NTUs
  • Formerly 13 NTUs (Yikes!)
• Sites that disturb > 20 or more acres
• Compliance Date - August 1, 2010
• Sites that disturb >10 or more acres
• Compliance Date - February 2, 2014

Stormwater: Rule 13

Municipal Separate Storm Sewer (MS4)

• EPA Rulemaking
• "Strengthen Stormwater Program"
  • Proposed Rule - Late 2011
  • Final Action - Late 2012
• Implications
  • Expand Effected Entities
  • Qualitative Standards for Post Construction Monitoring

Stormwater: Rule 13

Municipal Separate Storm Sewer (MS4)

• Recent Questionnaire / Audit Issued by EPA
• Recipients:
  • Regulated Entities (7 MS4)
  • Non-Regulated Entities (48 Non-Regulated)
  • Due October 2010

Surface Water Quality: General

Trends

• Watershed Approach
  • Chesapeake Bay (TMDL and Permits)
  • KY Sanitary District No. 1
• Water Quality Standards Revisions (Summer 2011) - Antidegradation, existing uses, etc.

Water: Proposed Rule Changes

Total Coliform Rule

• Small Systems criteria for reduced sampling when "well-operated"
• High Risk & Noncompliant may increase monitoring
• New requirements for seasonal systems
• MCLG & MCL forE. coli

Water: Proposed Rule Changes

Radon

• Multimedia Mitigation (MMM) with Indoor Air
• MCLG - 0 picoCuries/l
• MCL - 300 picoCuries/l
• AMCL - 4,000 picoCuries/l

Water: Proposed Rule Changes

Contaminant Candidate List 3 (CCL3)

• "May require regulation...."
• 116 Candidates
• Eg.
  • Acetochlor
  • Molybdenum
  • Perchlorate

Water: Sampling & Reporting

Disinfection Byproducts

• Initial Distribution System Evaluation
• Disinfection Byproduct Stage 1
• Disinfection Byproduct Stage 2
  • TTHMs - trihalomethanes
  • HAA5s - haloacetic acids

Water: Requirements

Wellhead Protection Phase II

• Large (>50,000) - 5 yrs. From Phase I Approval
• Medium (3,300 - 50,000) 7 yrs. From Phase I Approval
• Small (<3,300) - 10 yrs. From Phase I Approval

Conclusion

Compliance 101

• Proper reporting
• Follow schedules
• Know your programs (EPA vs. IDEM)
• Document, document, document
