Grand Lake St. Marys, Ohio

  1. 1. Grand Lake St. Marys, Ohio:Distressed designation and rules implementation By the ODNR Division of Soil and Water Resources April 14, 2012
  2. 2. Grand Lake - State Response• State Agency Directors led development of an action plan. 7/30/10• New Rules Proposed for the Agricultural Pollution Abatement Program.• Winter manure application• Nutrient management plans
  3. 3. Designating Watersheds“Distressed” 1501:15-5-20• DSWR Chief designates watershed• Soil and Water Conservation Commission Approval• Once designated triggers NMP and land application requirements• Considerations for designation
  4. 4. Designating Watersheds“Distressed” 1501:15-5-20Considerations:• Nutrient impaired by ag sources as determined by OEPA 303 (d) or TMDL report• Threats to public health• Periodic evidence of algal or cyanobacterial blooms capable of producing toxins• Contaminants in public or private water supplies• Contaminants in recreational water• Nuisances impacting aquatic life
  5. 5. Ohio EPA Reports:2010 303d (Integrated Report)2007 TMDL Report (approved by USEPA)Both document nutrient impacts from ag sources (land application of manure)
  6. 6. Threat to Health- worked with LHD/ODH- yes, reasonable chance
  7. 7. Periodic Evidence of Algal Bloomsand Toxins?• definitely
  8. 8. Samples Confirm Toxins(liver, nervous system, dermal impacts…)• microsystin (has WHO standards)• anatoxin-a• saxitoxin• cylindrospermopsin
  9. 9. Benchmark Criteria Promulgated by WHO for Microcystins: Drinking Water: 1µg L-1 Recreational Exposure: 20 µg L-1 (guidelines based on adult exposure) Photo By Linda Merchant- Masonbrink-Grand Lake, 2010
  10. 10. Presence or Threat ofContaminants in Public WaterSupply• Yes• GLSM is a public water supply for Celina (OAC 3745-1-29)• 45 out of 73 samples in 2010 exceeded 1 ppb microsystin (1.1 to >2000 ppb)• 100% of samples exceed 1 ppb in 2009• Note: finished water no tests > 1 ppb
  11. 11. Presence or Threat of Contaminantin Recreational Waters• Yes• GLSM is a primary contact recreational water (OAC 3745-1-29)• Eight out of 73 tests exceeded 20 ppb microsystin in 2010 (25.2 to >2000 ppb)• 80% of tests exceeded 20 ppb in 2009
  12. 12. Nuisance Conditions ImpactingAquatic Life• Yes• Several fish kills documented in 2009 and 2010• Division of Wildlife field officers cite likelihood of algal blooms causing dissolved oxygen depletion
  13. 13. GRAND LAKE ST. MARYS• DSWR Chief and Ohio Soil and Water Conservation Commission - designated “distressed” January 18, 2011• Nutrient Management Plans required by December 15, 2012• Winter Application restrictions take effect January 19, 2013
  14. 14. Who Must Follow This?• Anyone in the watershed managing over 100,000 gallons or 350 tons of manure a year• Unless you are already under permit by ODA or OEPA (14 out of about 300)
  15. 15. Land Application of ManureEffective when designated “distressed” January 19, 2011:NRCS Standard 633 Waste Utilization must be followed by all not under ODA/OEPA permit
  16. 16. Nutrient Management Plans1501:15-5-19• Plans need to be submitted to Mercer/Auglaize SWCD or Division of Soil & Water Resources by December 15th 2012• Plans can be in the form of the Ohio Nutrient Management Workbook or NRCS Comprehensive Nutrient Management Plan
  17. 17. Land Application of Manure1501:15-5-05Within two years after designation:• Shall not apply manure between December 15 and March 1 without prior approval (criteria being developed for this with local input)• Outside of dates above – no surface application of manure on frozen or snow covered ground • If it can be injected or incorporated, the application area is not considered to be frozen
  18. 18. Local Implementation• Guiding Principles – Respect for private property – Respect for our resources – Give people a chance – Help people succeed first – Use our regulatory backstop if needed • recalcitrance • gravity
  19. 19. What about Statewide Needs forNutrient Reduction?• Regional Issues (Ohio River, Lake Erie)• National Objectives (Gulf of Mexico, Great lakes)
  20. 20. The Ohio River Basin NY PA OH IL IN WV VA KY NC TN
  21. 21. State Nutrient ReductionStrategyOEPA lead, ODNR key support• Protect local waters (e.g., HABs, nutrient impairments)• Regional Goals (e.g., Ohio River, Lake Erie)• National Goals (e.g., Gulf of Mexico, Mississippi River, Great Lakes)• Draft due May 2011
