  1. Application of AAPFCO’s SUIP #25Calculation and Enforcement David L. Terry Division of Regulatory Services University of Kentucky

  2. Topics for Consideration 1. A Brief History of the Metal Standards 2. SUIP No. 25: What is it, anyway? 3. Some Arithmetic in Using the Standards

  3. SUIP No. 25A Brief History • 1993: Heavy Metals Task Force Discussed by Labeling and Definitions Committee to Address Concerns in CA (OP#47,p158) • 1993: Uniform Bills Committee decides to define ‘Adulteration’ to Include injury to humans, etc.(OP#48, p159) • 1997: ‘Adulteration’ made “Official” OP#51, p129) • 1997: “Fear in the Fields”-Added Urgency

  4. SUIP No. 25A Brief History (Cont.) • 1999 : First AAPFCO Metal Standards (SUIP No. 25) were the Canadian Standards-(OP# 52, p 55) • 2002: SUIP No. 25 with the Tabular Risk-Based Standards (OP# 55, p 57)

  5. SUIP No. 25What is it, Anyway?? • Risk-Based (Human Health Protective) • Probability Level-90% • Considered Most Likely Pathways of Ingestion • Used Published Literature to Assess Risk • Not Technology Based • Defines Adulteration

  6. Enlighten Enforcement • Acceptable Standards: SUIP No. 25 • Validated Methods: AOAC, et. al. • Used as a condition for registration • Metal analysis not required on label • Statements acceptable on label are:

  7. SUIP No. 26 “When applied as directed, this product meets the guidelines for metals adopted by the AAPFCO”

  8. SUIP No. 27 “Information regarding the contents and levels of metals in this product is available on the internet: http://www.aapfco.org/metals”

  9. SUIP No. 27 “Information regarding the contents and levels of metals in this product is available on the internet: http://www.regulatory-info-xx.com” Where xx = Co. ID

  10. Now for the Arithmetic**Calculation of Limits** • Getting Started • Need the Standards • Need to Understand the Standards • Fertilizer Information Needed • Available Phosphate (P2O5) Guarantee • Micro-Nutrient Guarantees • Turn on Calculator

  11. SUIP No. 25 Metals,Max. Allowable Conc. per 1% P2O5per 1% Micro.* ppmppm Arsenic 13 112 Cadmium 10 83 Cobalt 3,100 23,000** Lead 61 463 Mercury 1 6 Molybdenum 42 300** Nickel 250 1,900 Selenium 26 180 Zinc 420 2,900**

  12. SUIP No. 25 FootnotesExplanations * Micro-nutrients as defined by T-9 are: B, Cl, Co, Cu, Fe, Mn, Mo, Na, and Zn ** Applies only when NOT GUARANTEED

  13. To use the Table: • Products with Either A Guarantee for P OR Micro-Nutr’s but not both: • Multiply the percent guaranteed P2O5or sum of the guaranteed percentages of all micronutrientsas defined in Official Fertilizer Term T-9in each product by the value in the appropriate column in the Table to obtain the maximum allowable concentration (ppm) of these metals. • The minimum value for P2O5 utilized as a multiplier shall be 6.0 • The minimum value for micronutrients utilized as a multiplier shall be 1.0

  14. To use the Table: • Products with Guarantees for both P and Micro-Nutr’s: • Multiply the guaranteed percent P2O5 by the value in the appropriate column, and • multiply the sum of the guaranteed percentages of the micronutrients by the value in the appropriate column. • Utilize the higherof the two resulting values as the maximum allowable concentrations.

  15. Biosolids, and all compost products4, shall be adulterated when they exceed the levels of metals permitted by the US EPA 40 CFR Part 503. • Dried biosolids and manure, as well as manipulated manure products either separately or in combination, shall also be deemed adulterated when they exceed the levels of metal permitted by the US EPA 40 CFR Part 503. • Hazardous waste derived fertilizers (as defined by EPA) shall be adulterated when they exceed the levels of metals permitted by the US EPA 40 CFR Parts 261, 266 and 268.
