Case Studies
• Leaded Gasoline
• Mercury in Consumer Batteries
• CCA Treated Wood
![Page 4: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/4.jpg)
Other Notable Mandatory P2 Measures
• Toxics in Packaging Standards
• DOT Lead Paint Elimination
![Page 5: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/5.jpg)
Toxics in Packaging Standards
• Enacted in 1993• 403.7191, Florida Statutes• Based on Council of Northeast Governors
(CONEG) model legislation• Adopted by 26 states • Sets maximum allowable levels of
lead,mercury, cadmium and helavalent chormium in packaging components
![Page 6: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/6.jpg)
FDOT Lead Paint Elimination
• Part of settlement agreement for the FDOT Fairbanks disposal pit
• FDOT agreed to switch to non-lead based paint for road striping
• FDOT at that time was largest lead paint user in state

Lead in Gasoline
![Page 9: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/9.jpg)
Lead in Gasoline
• Tetra ethyl lead use started in 1930s to improve engine performance
• Introduction of catalytic converters and increasing health impacts forced phase-out
• EPA set mandatory standards in 1985 reducing lead in gasoline by 90%
• Leaded gasoline being phased out globally but still in use in many countries

Mercury in Consumer Batteries
![Page 13: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/13.jpg)
Florida Mercury Battery Legislation
• Enacted in 1993• 403.7192, Florida Statutes• Followed similar Minnesota law• Set maximum Hg levels in zinc-
carbon and alkaline batteries• Prohibited sale of mercuric oxide
button batteries• Supported by the battery industry
![Page 14: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/14.jpg)

Florida Regulatory and Cleanup Criteria for Arsenic
• Drinking Water MCL: 50 ug/L (federal MCL lowered to 10 ug/l by EPA 1/2001)
• TCLP: 5 mg/L
• Soil Clean Up Target Levels (SCTLs)– Residential: 0.8 mg/kg– Industrial: 3.7 mg/kg– Leachable: 27.5 mg/kg

Environmental Concerns With CCA Treated Wood
A. Ash from combustion of wood fuel mixtures
containing CCA wood can be a hazardous waste
B. Arsenic leaches from CCA wood used as
decorative ground cover mulch
C. Arsenic leaches from CCA wood discarded in
landfills
D. Soils under CCA treated decks are being
contaminated with arsenic

“…Copper Azole is a significant improvement overtraditional CCA treatment as it substantially reducesreliance on and exposure to the more toxic heavy metalssuch as chromium and arsenic throughout all stages ofproduction, distribution and use. …it is environmentallyresponsible to specify or use Copper Azole treated lumber.”

“The aim of the development program was to create awood preservative that had the same excellent timberdurability properties as CCA but without the inclusionof chromium or arsenic. An additional desired featurewas complete compatibility with existing CCA treatmentplants and processes.”

SED Data Conclusions
• Arsenic exceedances are occurring in groundwater, even when no spill is indicated.
• Soils show Arsenic levels above the Soil Cleanup Goals both in the maintenance areas and in the playing areas.
• Little difference was noted between dissolved and total Arsenic concentrations
![Page 71: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/71.jpg)
Conclusions from examining Leachability of soils where arsenicals
have been applied...
• To date, 65 samples have been collected from SED golf courses and analyzed for both total Arsenic and SPLP Arsenic.
• 55% of the samples examined were “leachable” with respect to 50 ug/L Arsenic.
• 86% of the samples examined were “leachable” with respect to 10 ug/L Arsenic.
• When dealing with large areas, sandy soils, and shallow groundwater, approximately 15 mg/Kg Total Arsenic has been demonstrated by SPLP analysis to be a reasonable LSCTL (50 ug/L).
• This value will be far less if considering a groundwater standard of 10 ug/L.
![Page 72: Mandatory Pollution Prevention: A Record of Success Presentation to the First Joint Pollution Prevention and Environmental Essentials Conference August](https://reader035.vdocuments.net/reader035/viewer/2022062421/56649dd85503460f94acdd7e/html5/thumbnails/72.jpg)
Another case study… a portion of an SED golf course that was operated for
approximately 35 years.• Because the RPO of this portion intends to
develop the property for residential use, his concern for liability prompted sampling soils on 100X100’ grids. Over 400 soil samples were collected from approximately 14 acres.
• The parcel did not contain the maintenance area. It was comprised solely of former playing areas.
• Nothing known about the golf course is atypical of the operation of other golf courses in Southeast Florida.
• The site has not been operated as a golf course for approximately 7 years. No application of arsenicals has occurred since before 1995.

Arsenic.• Removal of the top 2’ of soils would only serve to
expose the 2-4’ soils, which also exceeded the 0.8 mg/Kg.
• 48% of the soil samples exceeded 3.1 mg/Kg Arsenic.
• The mean soil concentration (400+ samples) is 5.4 mg/Kg Arsenic.
• 8% of the soil samples exceeded 15 mg/Kg Arsenic, which was the leachability SCTL for this site, established with the use of SPLP analyses.

• The highest groundwater concentration reported was 655 ug/L Arsenic.
• 80% of the shallow groundwater monitoring well samples (12-15’) exceeded 50 ug/L Arsenic.
• All of the shallow groundwater monitoring wells exceeded 10 ug/L Arsenic.
