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
SUIP No. 25 A 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
SUIP No. 25 A 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)
SUIP No. 25 What 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
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:
SUIP No. 26 “When applied as directed, this product meets the guidelines for metals adopted by the AAPFCO”
SUIP No. 27 “Information regarding the contents and levels of metals in this product is available on the internet:
http://www.aapfco.org/metals”
SUIP No. 27 “Information regarding the contents and levels of metals in this product is available on the internet:

Where xx = Co. ID
Now for the Arithmetic **Calculation of Limits** • Getting Started – Need the Standards – Need to Understand the Standards • Fertilizer Information Needed – Available Phosphate (P 2 O 5 ) Guarantee – Micro-Nutrient Guarantees • Turn on Calculator

SUIP No. 25 Footnotes Explanations * Micro-nutrients as defined by T-9 are:
B, Cl, Co, Cu, Fe, Mn, Mo, Na, and Zn
** Applies only when NOT GUARANTEED
To use the Table:
Products with Either A Guarantee for P OR Micro Nutr’s but not both:
Multiply the percent guaranteed P 2 O 5
or
guaranteed percentages of all micronutrients sum of the
as defined in Official Fertilizer Term T-9
in each product by the value in the appropriate column in the Table to obtain the maximum allowable concentration (ppm) of these metals.
The minimum shall be 6.0
value for P 2 O 5 utilized as a multiplier
The minimum value for micronutrients utilized as a multiplier shall be 1.0
To use the Table:
Products with Guarantees for both P and Micro Nutr’s:
Multiply the guaranteed percent P 2 O 5 appropriate column,
and
by the value in the multiply the sum of the guaranteed percentages of the micronutrients by the value in the appropriate column. Utilize the
higher
of the two resulting values as the maximum allowable concentrations.
•Biosolids, and all compost products 4 , 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
