Part 17.	Statements of Basis, Specific Statutory Authority and Purpose
17.1.	Adopted April 10, 2001 – Effective May 30, 2001
STATUTORY AUTHORITY:
The Commissioner of Agriculture, Colorado Department of Agriculture, adopts these permanent rules pursuant to the provisions and requirements of the Colorado Commercial Feed Law, § 35-60- 109(1), C.R.S. (2000).
PURPOSE:
The purpose of these rules is to comply with the requirements of the Colorado Commercial Feed to provide specific guidelines for the manufacture, labeling and distribution of commercial feed.
These rules are designed to:
-	 Set standards for the correct labeling of livestock and pet food.
-	 Set standards for good manufacturing practices for medicated livestock feed.
FACTUAL AND POLICY ISSUES:
The factual and policy issues encountered in the proposal of these permanent rules are as follows:
1.	The Colorado Commercial Feed Law was repealed and reenacted effective January 1, 2000. That statute requires the Commissioner to adopt the Official Definitions of Feed Ingredients and Official Feed Terms adopted by the Association of American Feed Control Officials, Inc. (AAFCO), as published in the official publication of such association.
2.	These new, revised rules are based upon national standard (model) regulations developed by AAFCO, a nation-wide group of regulatory officials. They are specifically for the purpose of promoting standardization between states for the animal feed industry.
3.	Over 30% of the states have adopted the AAFCO model regulations. These rules are widely accepted by Colorado and national feed companies. Adoption of these rules would help to ensure uniform labeling requirements.
4.	The Department met with the Colorado Grain and Feed Association’s (CFGA) Feed Committee throughout the rule drafting process. The CGFA supports these new rules and regulations.
5.	Two sets of rules are needed, one for livestock feed, the other for pet food. Livestock feed rules are specific to matters regarding production, animal growth and weight gain, and use of medications in feed. Pet food rules employ separate criteria for complete and balanced nutrition and provide regulatory guidance for advertising and claims frequently found on pet food labels.
17.2.	Emergency Rule Adopted October 19, 2006 – Effective October 19, 2006
Statutory Authority:
These emergency amendments to the Rules Pertaining to the Administration and Enforcement of the Colorado Commercial Feed Law, §§ 35-60-101 - 115, C.R.S., are proposed for adoption by the Commissioner pursuant to his authority in Section 35-60-109(1), C.R.S.
Purpose:
The purposes of these emergency amendments to the rules are as follows:
(a)	To specify in rule that all information required or requested by the Commissioner, including lawful presence documentation required under Section 24-76.5-103, C.R.S., must be complete and accurate, and to specify the legal consequences of noncompliance with this rule.
(b)	To document and record the statements of statutory authority, basis and purpose for these rules.
Factual Basis:
(a)	On August 1, 2006, Section 24-76.5-103, C.R.S., took effect following its enactment in House Bill 06S-1023 by the General Assembly in the July, 2006, special legislative session.
(b)	Currently, neither the Commercial Feed Law nor its associated rules specify that individuals who apply for registrations must comply with the verification documentation requirements of Section 24-76.5-103, C.R.S.
(c)	These emergency rules are necessary to provide the Commissioner with specific legal authority to deny applications for registration or renewal of existing registrations from natural persons who do not provide sufficient documentation to comply with Section 24-76.5-103, C.R.S., and to revoke existing registrations if the information provided in connection with an application is later proven to be false.
(d)	These emergency rules are necessary to fulfill the purposes described above prior to the adoption of permanent rules to that effect.
17.3.	Adopted November 13, 2006 – Effective January 1, 2007
Statutory Authority:
These permanent amendments to the Rules Pertaining to the Administration and Enforcement of the Colorado Commercial Feed Law, §§ 35-60-101 - 115, C.R.S., are proposed for adoption by the Commissioner pursuant to his authority in Section 35-60-109(1), C.R.S.
Purpose:
The purposes of these permanent amendments are as follows:
(a)	To specify in a permanent rule that all information required or requested by the Commissioner, including lawful presence documentation required under Section 24-76.5-103, C.R.S., must be complete and accurate, and to specify the legal consequences of noncompliance with this rule.
(b)	To document and record the statements of statutory authority, basis and purpose for these rules.
Factual Basis:
(a)	On August 1, 2006, Section 24-76.5-103, C.R.S., took effect following its enactment in House Bill 06S-1023 by the General Assembly in the July, 2006, special legislative session.
(b)	On October 19, 2006, the Commissioner adopted emergency rules specifying that individuals who apply for registrations under the Commercial Feed Law must comply with the verification documentation requirements of Section 24-76.5-103, C.R.S.
(c)	These permanent amendments to the rules are necessary to provide the Commissioner with specific legal authority, following the expiration of the emergency rules adopted on October 19, 2006, to deny applications for registration or renewal of existing registrations from natural persons who do not provide sufficient documentation to comply with Section 24-76.5-103, C.R.S., and to revoke existing registrations if the information provided in connection with an application is later proven to be false.
(d)	These permanent amendments to the rules are necessary to make permanent the provisions of the emergency rules adopted by the Commissioner on October 2, 2006.
17.4.	Adopted November 1, 2007 – Effective December 30, 2007
Statutory Authority:
These amendments are proposed for adoption by the Commissioner pursuant to his authority in section 35-60-109(1), C.R.S.
Purpose:
The purposes of these amendments are as follows:
(a)	To amend the name of the Act used in the Rules to correspond with the new name adopted under Senate Bill 07-207.
(b)	Remove the definition of “contract feeder.”
(c)	To clarify the reporting requirements associated with the respective distribution fees.
(d)	To specify the due date of the distribution fees and report.
(e)	To specify the expiration date of a commercial feed registration.

(g)	Update the references to the official publications of the Association of American Feed Control Officials (AAFCO) incorporated by reference to the 2007 version.
(h)	To correct typographical errors.
Factual Basis:
(a)	On May 22, 2007, the Colorado Commercial Feed Law was amended by Senate Bill 07-207. The title of the law was amended to the Colorado Feed Law.
(b)	The registration expiration date and the filing date for distribution fees and reports were removed from the Colorado Feed Law. The rules maintain the existing date for the submission of distribution reports and fees, and establish a new expiration date for feed registration to coincide with the distribution due date. This change will allow industry to file both reports at one time.
(c)	A new definition for “contract feeder” was adopted in the Colorado Feed Law which supersedes the current rule definition.
(d)	The current rules require the guaranteed analysis to be listed on an “as fed” basis. The AAFCO national standard requires it be listed on an “as is” basis.
17.5.	Adopted February 11, 2015 – Effective March 30, 2015
The Commissioner's authority for the adoption of these permanent Rule amendments is set forth in Sections 35-60-102(2) and 35-60-109(1), C.R.S.
The Purpose of this rulemaking is to:
1.	Edit Part 1 Legal Authority to include all rulemaking authority in 35-60, C.R.S. 
2.	Update the references throughout the Rules to the official publication of the Association of American Feed Control Officials (AAFCO) incorporated by reference to the 2015 version.
3.	Edit commercial feed definition Part 2.3. for clarity. 
4.	Add Part 4.1.4.11.6. to specify a labeling exemption to allow manufacturers of wild bird seed products to use a composition statement instead of a guaranteed analysis statement.
5.	Remove Section (5)(III) “In lieu of ingredient statement.”
6.	Remove “pet food” from Part 11.1.6. Adulterants 
7.	Change the date in Part 15 and Part 16.2. for registrations and the due date for small package distribution reports and fees to December 31st.
8.	Correct typographical errors.
9.	Reformat Rules to meet new rulemaking guidelines.
Factual and Policy Issues:
The factual and policy issues encountered in the proposal of these permanent Rules are as follows:
1.	The previous version of these Rules did not include the rulemaking authority under 35-60-102(2), C.R.S. 
2.	Numerous changes to the AAFCO publication have occurred since the printing of the 2007 version which is referenced in the Rules. This change will make our Rules more consistent with other states’ feed Rules
3.	Purchasers of wild bird seeds are generally more interested in the composition of the seed mix rather than nutritional guarantees. This voluntary change in labeling will allow manufacturers the option of using a composition statement to convey that information.
4.	The option of filing an ingredient list with the state in lieu of listing the ingredients on the label makes it more difficult for the public to know what is in the feed that they purchase. This option has not been exercised by feed manufacturers in Colorado in many years,
5.	Pet food adulterants are now covered in the Pet Food Rules (8 CCR 1202-7) and no longer needs to be addressed in this Rule.
6.	The Colorado Department of Agriculture license and registration expiration dates have been moved to the calendar year in order to consolidate licensing for the Department. 
7.	These amendments incorporate changes as a result of the Department’s Regulatory Efficiency Review Process.
17.6.	Adopted February 10, 2016- Effective March 30, 2016
The Commissioner's authority for the adoption of this permanent Rule amendment is set forth in Section 35-60-109(1), C.R.S.
The Purpose of this rulemaking is to:
1.	Add Part 3.1.9 to include the requirement of the date of manufacture, processing, packaging, or repackaging or a code that permits the determination of the date to be included in the label.
Factual and Policy Basis
The factual and policy issue pertaining to the adoption of this permanent Rule amendment is as follows:
1.	The date of manufacture, processing, packaging, or repackaging or a code that permits the determination of the date as required in Section 35-60-106(1)(g), C.R.S., is being added to the Rule so that the Rule will contain the complete requirements for labeling an animal feed product. 
17.7.	Adopted November 9, 2016- Effective December 30, 2016
The Commissioner's authority for the adoption of this permanent Rule amendment is set forth in § 35-60-103(1), § 35-60-105(3)(a), and § 35-60-105(4), C.R.S.
The Purpose of this rulemaking is to:
Change the date in Part 15 and Part 16.2 for registrations and the due date for small package distribution reports and fees to January 31st.
Factual and Policy Basis
The factual and policy issue pertaining to the adoption of this permanent Rule amendment is as follows:
1.	Currently, feed registrants have to log into the Department’s licensing system at separate times of the year to complete the registration and reporting process. This can be burdensome to registrants and be prone to mistakes. 
2.	After consulting with industry stakeholders, the Department has proposed to synchronize all deadlines associated with the larger registration process to make the process more efficient for registrants.
17.8.	Adopted September 20, 2017 – Effective OctoberNovember 30, 2017
Statutory Authority
The Commissioner's authority for the adoption of this permanent Rule amendment is set forth in § 35-60-109(1) C.R.S.
Purpose
The Purpose of this rulemaking is to update the references to the current publication of the Association of American Feed Control Officials; add “Neutral Detergent Fiber” to the list of nutrient guarantees; remove the required minimum zinc guarantee for Swine; add required minimum Acid Detergent Fiber and Neutral Detergent Fiber guarantees for Equines; add Quantity Statement requirements for clarity; and add requirements for guarantees of dietary starch and fructans. 
Factual and Policy Basis
1.	Numerous changes to the AAFCO Official publication have occurred since the printing of the 2015 version which is referenced in the rules. The change to the 2017 version is reflected throughout the rule.  Updating the rule to follow the 2017 AAFCO Model regulations will make our rules more consistent with other states’ feed rules. This is reflected by the changes to Part 4.1.4. Guarantees, Part 4.1.8 Quantity Statements, and Part 5.12. Guarantees for Dietary Starches. 
2.	These amendments incorporate changes as a result of the department’s regulatory efficiency review process.
