    2. 2. Background• An NPDES permit has been required since Oct 31, 2011• According to the GA EPD permit, if you exceed the threshold for adulticiding, you are required to submit an Notice Of Intent• Remember – After you submit your NOI you cannot apply pesticides until the NOI is approved by the GA EPD – If you don’t hear anything after 2 weeks, it has been approved GA EPD Pesticide General Permit (PGP) Info: 2

    4. 4. Truck spray (figuring acreage):1 foot = 0.000189393939 miles1 acre = 43,560 square feetSo,247 miles = 1304160.003 feet (miles driven while spraying)300 feet (spray swath)1298880.003 feet x 300 feet for the swath equals391248000.81 square feetand that equals 8981.82 acres 4
    5. 5. Another way to calculate acreage sprayed bytruck is to note your actual spray time (somespray pumps will monitor hours of use) andthe mph at which you are spraying.Acres sprayed are:181.8 acres per hour at 5 mph363.6 acres per hour at 10 mph545.5 acres per hour at 15 mph727.3 acres per hour at 20 mph 5
    6. 6. Things that should already be done Pesticide Discharge Management Plan (PDMP) (keep on file) Notice Of Intent (NOI) (submit to EPD)Check the NPDES page on the GMCA website for examples of PDMPs and NOIs Maintain records of equipment calibrations (keep on file) Maintain records of chemical application sites and amounts applied (keep on file) Effluent limitations  Technology based – Develop thresholds – Integrated Mosquito Management (IMM) – Federal Insecticide Fungicide & Rodenticide Act (FIFRA)  Water quality based – meet standards 6
    7. 7. Things that should already be done Post-spray analyses (keep on file) • Efficacy • Non-target effects (fish kills) Adverse incident reports • File as required • Meet deadlines Document corrective action when needed • Changes to your PDMP • Adverse incidents, spills, non-targets, etc. Compile a biennial report (keep on file) 7
    8. 8. Reports are kept on file, NOT submitted. Biennial Reporting Name of Operator Name of contact person For each treatment area - Waters of Georgia in the treatment area - Pesticide use patterns (mosquitoes, aquatic weeds, forest canopy) - Target pests - Company/Agency name - Applicator names and contact information - Total amount of pesticide, EPA registration number, application method - Whether pest control activity was addressed in the PDMP - Annual report of adverse incidents - Description of corrective actions, including spills /BIENNIALOPERATIONSREPORTblank.doc 8
