# ACTION:

Final rule. 

# SUMMARY:

On December 15, 2004, the Drug Enforcement Administration (DEA) published a Final Rule corrected January 4, 2005) that implemented new regulations concerning chemical mixtures that contain any of the 27 listed chemicals. The Final Rule added a new provision not previously raised by DEA in any proposed rulemaking. This newly introduced provision exempted domestic and import transactions in chemical mixtures that are regulated solely due to the presence of the List II solvent chemicals acetone, ethyl ether, 2-butanone, or toluene from the Controlled Substances Act (CSA) recordkeeping and reporting requirements. Because this exemption was not previously proposed in any rulemaking, DEA implemented this exemption on an interim basis and requested public comment on this exemption provision. 

Based upon a review of all comments, DEA is finalizing this exemption. As such, domestic and import transactions in chemical mixtures containing the List II chemicals acetone, ethyl ether, 2-butanone, and toluene shall be exempt from CSA chemical recordkeeping and reporting requirements. 

# DATES:

This Final Rule is effective March 12, 2007.

# SUPPLEMENTARY INFORMATION:

## I. Background 

### Historical Legal Status of Chemical Mixtures 

The Chemical Diversion and Trafficking Act of 1988 (CDTA), (Pub. L. 100-690) created the definition of “chemical mixture” (21 U.S.C. 802(40)), and exempted chemical mixtures from regulatory control. The CDTA established 21 U.S.C. 802(39)(A)(vi), as amended by Title VII of Public Law 109-177, to exclude “any transaction in a chemical mixture” from the definition of a “regulated transaction.” The exemption of all chemical mixtures, however, provided traffickers with an unregulated source for obtaining listed chemicals for use in the illicit manufacture of controlled substances. 

To remedy this situation, the Domestic Chemical Diversion Control Act of 1993 (Pub. L. 103-200) (DCDCA), enacted in April 1994, subjected chemical mixtures containing listed chemicals to CSA regulatory requirements, unless specifically exempted by regulation. The DCDCA, therefore, subjected all regulated chemical mixtures to recordkeeping, reporting, and security requirements of the CSA. Additionally, the DCDCA added a registration requirement for handlers of regulated List I chemical mixtures. 

                    The DCDCA, however, also amended 21 U.S.C. 802(39)(A)(vi), as amended by Title VII of Public Law 109-177, to provide the Attorney General with the authority to establish regulations exempting chemical mixtures from the definition of a “regulated transaction” “based on a finding that the mixture is formulated in such a way that it cannot be easily used in the illicit production of a controlled substance and that the listed chemical or chemicals contained in the mixture cannot be readily recovered” (21 U.S.C. 802(39)(A)(vi) as amended by Title VII of Pub. L. 109-177). This authority has been delegated to the Administrator of DEA by 28 CFR 0.100 and redelegated to the Deputy                           ( print page 10926)                        Administrator under 28 CFR Appendix to Subpart R, section 12.                 

Prior to publication of a final rulemaking, chemical mixtures containing listed chemicals have been treated as exempt from CSA regulatory control. Regulations regarding the exemption of chemical mixtures were initially proposed by DEA on October 13, 1994, as part of its proposed regulations to implement the DCDCA (59 FR 51888). In response to industry concerns, the proposed regulations were withdrawn on December 9, 1994, (59 FR 63738). 

DEA proposed new regulations regarding the exemption of chemical mixtures by publishing a new NPRM entitled “Exemption of Chemical Mixtures” on September 16, 1998 (63 FR 49506). DEA proposed the following three-tiered approach to identify which chemical mixtures qualify for automatic exemption: (1) It contains a listed chemical at or below an established concentration limit; or (2) it falls within a specifically defined category; or (3) the manufacturer of the mixture applies for and is granted a specific exemption for the product. 

On December 15, 2004, DEA published a final rule which specified criteria used to determine whether chemical mixtures qualify for automatic exemption from CSA chemical regulatory controls for 27 listed chemicals (69 FR 74957; corrected at 70 FR 294, January 4, 2005). Those chemical mixtures that do not meet the exemption criteria are treated as regulated chemicals and therefore, subject to CSA chemical regulatory controls. 

## Chemical Mixture Definition 

Title 21 U.S.C. 802(40) defines the term “chemical mixture” as “a combination of two or more chemical substances, at least one of which is not a List I chemical or a List II chemical, except that such term does not include any combination of a List I chemical or a List II chemical with another chemical that is present solely as an impurity.” Therefore, a chemical mixture contains any number of listed chemicals along with any number of non-listed chemicals. A combination of only listed chemicals is, therefore, not a chemical mixture pursuant to the CSA definition. As such, the regulatory controls pertaining to each individual listed chemical are applicable. 

It is DEA's longstanding policy that the combination of a listed chemical in an inert carrier is not considered a chemical mixture. An inert carrier can be any chemical that does not interfere with the listed chemical's function but is present to aid in the delivery of the listed chemical so it can be used in some chemical process. Examples include, but are not limited to, solutions of listed chemicals such as methylamine in water or hydrogen chloride dissolved in water or alcohol. Persons who question if their formulations are chemical mixtures should contact DEA for guidance. 

## New Interim Chemical Mixture Exemption Category 

The Final Rule published on December 15, 2004, (69 FR 74957; corrected at 70 FR 294, January 4, 2005) also added, on an interim basis, a new exemption category. DEA determined that certain solvent-based mixtures involving silicon-based products, paint-related materials, and other solvent-based chemical mixtures containing acetone, ethyl ether, 2-butanone, and toluene are not likely to be diverted domestically. These solvent chemicals are mostly a concern because they are used in cocaine and heroin processing, which occurs outside the United States. 

Therefore, the December 15, 2004 rulemaking created a new exemption category for these mixtures. Domestic and import transactions in chemical mixtures that are regulated solely due to the presence of the List II solvent chemicals acetone, ethyl ether, 2-butanone, or toluene were removed, on an interim basis, from the definition of a regulated transaction by adding a new paragraph to 21 CFR 1310.08. Methyl isobutyl ketone, also a List II solvent chemical, was not included because domestic and import transactions in that chemical have already been excluded from the definition of a regulated transaction at 21 CFR 1310.08. 

This new exemption (for domestic and import transactions in chemical mixtures containing the List II chemicals acetone, ethyl ether, 2-butanone, and toluene) was not discussed in the original NPRM published on September 16, 1998 (63 FR 49506). Therefore, this exemption was implemented on an interim basis with opportunity for public comment in the December 15, 2004 rulemaking (69 FR 74957; corrected at 70 FR 294, January 4, 2005). DEA solicited comments on this portion of the rulemaking. 

## II. Comments Received Regarding the Interim Regulations 

DEA received three comments in response to the December 15, 2004, rulemaking (69 FR 74957) from interested parties. Two comments were from trade associations, and one comment was from a chemical manufacturer. In general, the comments supported efforts by DEA to regulate chemical mixtures that have potential use to drug traffickers. Each comment specifically supported finalization of the exemption for domestic and import transactions for chemical mixtures containing the List II solvent chemicals acetone, ethyl ether, 2-butanone, and toluene. 

Two comments, however, requested that the exemption be expanded to include certain exports of such chemical mixtures. The comments suggested that DEA only regulate exports of such mixtures to certain specific countries of concern. Given the applicability of such solvents for both cocaine and heroin processing, however, the geographic regions of concern are extremely widespread. Additionally, DEA has concerns that exports of solvent chemical mixtures can be subject to re-exportation from destination countries. DEA believes that such exports of chemical mixtures should not be exempted since exports of these chemical mixtures could have significant potential for diversion. Therefore, these chemical mixtures, unless otherwise exempt, are subject to the export and other CSA chemical regulatory requirements. 

One commenter expressed concerns regarding the regulatory language found in 21 CFR 1310.08(l) stating that, “Domestic and import transactions in chemical mixtures that contain acetone, ethyl ether, 2-butanone, or toluene unless regulated because of being formulated with another listed chemical above the concentration limit” shall be excluded transactions. The commenter stated that the regulatory language does not make it clear that this exemption applies if the mixture contains more than one of these chemicals (i.e. contains two or more of the following: acetone, ethyl ether, 2-butanone or toluene). The commenter expressed concerns that enforcement officials may deem chemical mixtures containing more than “one” of these solvents as regulated if the total quantity exceeded the List II concentration limits. DEA agrees. Therefore, DEA is modifying 21 CFR 1310.08(l) to read, “Domestic and import transactions in chemical mixtures that contain acetone, ethyl ether, 2-butanone, and/or toluene, unless regulated because of being formulated with other List I or List II chemical(s) above the concentration limit” shall be excluded. 

### Clarification of Concentration Limits 

                    As DEA stated in its Final Rule establishing concentration limits for the vast majority of chemical mixtures (69 FR 74957, December 15, 2004), and                           ( print page 10927)                        codified at 21 CFR 1310.14(c), mixtures containing a listed chemical in concentrations equal to or less than those specified in the “Table of Concentration Limits” are designated as exempt from specified provisions set forth in that section. The concentration limit is set at 35 percent (by weight or volume) for the cumulative amount of acetone, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK), toluene, and ethyl ether. Therefore, the table in 21 CFR 1310.14(c) specifies that for exports, the limit applies to the specific chemical or any combination of acetone, ethyl ether, 2-butanone, methyl isobutyl ketone, and toluene, if present in the mixture by summing the concentrations for each chemical. For example, an export involving a chemical mixture containing 20 percent acetone and 20 percent ethyl ether would not be exempt because the cumulative total of 40 percent exceeds the 35 percent concentration limit.                 

### Final Action Taken in This Rulemaking 

After considering all comments, DEA has decided to exempt domestic and import transactions in chemical mixtures that contain acetone, ethyl ether, 2-butanone, and/or toluene under 21 CFR 1310.08 pursuant to 21 U.S.C. 802(39)(A)(iii) because regulation of such transactions has been determined to be unnecessary for the enforcement of the CSA. DEA determined that there is not a significant risk of domestic diversion for these chemical mixtures. 

### Specific Requirements That Will Apply to Regulated Chemical Mixtures Containing List II Chemicals Upon Publication of This Final Rule 

The above exemption only exempts such chemical mixtures from the domestic recordkeeping and import notification requirements. All other CSA chemical regulatory provisions, as specified in detail in the December 15, 2004 rule [69 FR 74957; corrected at 70 FR 294, January 4, 2005], shall apply. 

## III. Exemption Authority 

                    The CSA authorizes DEA, pursuant to 21 U.S.C. 802(39)(A)(iii), to remove certain transactions in listed chemicals from the definition of a regulated transaction that are unnecessary for enforcement of the CSA. Based on comments to the                     **Federal Register**                     proposed rule “Exemption of Chemical Mixtures” (63 FR 49506, September 16, 1998), DEA identified certain transactions in mixtures of acetone, ethyl ether, 2-butanone, and toluene that are unlikely sources for diversion. DEA was informed that tens of thousands of domestic transactions in these chemical mixtures occur annually. DEA determined that the regulation of domestic and import transactions in mixtures containing the chemicals acetone, ethyl ether, 2-butanone, and toluene were unnecessary for enforcement of the CSA and should be removed from the definition of a regulated transaction.                 

Since the NPRM to this rulemaking did not discuss this exemption, the public did not have the opportunity to comment on the exclusion of these transactions from the definition of a regulated transaction. 

However, to avoid unnecessary burdens on affected companies during the pendency of proceedings in this matter, DEA decided to include as part of its December 15, 2004, Final Rule an interim rule, with request for comment, removing these transactions from the definition of a regulated transaction. Now that DEA has had the opportunity to solicit and review comments, the exemption is being finalized in this rule. 

## IV. Regulatory Certifications 

### Regulatory Flexibility Act 

DEA has become aware that a substantial number of chemical mixtures that are not useful to traffickers could potentially be regulated if the chemical mixtures that are subject to this rulemaking were not excluded from certain regulatory requirements. DEA determined that the regulation of these chemical mixtures is not necessary for enforcement of the CSA. Therefore, DEA decided to exempt these chemical mixtures from regulatory controls by exemption of certain types of transactions. 

DEA notes that the List II solvent chemicals acetone, ethyl ether, 2-butanone, and toluene contribute to the largest number of potentially regulated chemical mixtures of List II chemicals. To limit the number of potentially regulated chemical mixtures to those necessary for enforcement of the CSA, DEA decided to define all domestic and import transactions of mixtures in these List II solvent chemicals as exempt transactions. This exemption applies to all persons that handle these chemical mixtures and not only to those who are represented in the comments. DEA previously implemented this exemption and is finalizing the exemption in this rulemaking. 

In accordance with the Regulatory Flexibility Act (5 U.S.C. 605(b)), the Deputy Administrator has reviewed this regulation and by approving it certifies that this regulation will not have a significant economic impact upon a substantial number of small entities. 

### Executive Order 12866

This regulation has been drafted and reviewed in accordance with Executive Order 12866, Section 1(b), Principles of Regulation. DEA has determined that this rule is a “significant regulatory action” under Executive Order 12866, Section 3(f), Regulatory Planning and Review, and accordingly this rule has been reviewed by the Office of Management and Budget. This rule finalizes an exemption for domestic and import transactions involving the List II chemicals acetone, ethyl ether, 2-butanone, and toluene. 

### Executive Order 12988

This regulation meets the applicable standards set forth in Sections 3(a) and 3(b)(2) of Executive Order 12988. 

### Executive Order 13132

This rulemaking does not preempt or modify any provision of state law; nor does it impose enforcement responsibilities on any state; nor does it diminish the power of any state to enforce its own laws. Accordingly, this rulemaking does not have federalism implications warranting the application of Executive Order 13132. 

### Unfunded Mandates Reform Act of 1995 

This rule will not result in the expenditure by state, local, and tribal governments, in the aggregate, or by the private sector, of $118,000,000 or more in any one year, and will not significantly or uniquely affect small governments. Therefore, no actions were deemed necessary under the provisions of the Unfunded Mandates Reform Act of 1995. 

### Congressional Review Act 

This rule is not a major rule as defined by Section 804 of the Small Business Regulatory Enforcement Fairness Act of 1996 (Congressional Review Act). This rule will not result in an annual effect on the economy of $100,000,000 or more; a major increase in costs or prices; or significant adverse effects on competition, employment, investment, productivity, innovation, or on the ability of United States-based companies to compete with foreign-based companies in domestic and export markets. 

### Paperwork Reduction Act 

                    This rulemaking finalizes an exemption provision which reduced the paperwork burden on handlers of acetone, ethyl ether, 2-butanone and toluene. By exempting domestic and import transactions involving chemical mixtures containing these List II chemicals DEA is not subjecting these                           ( print page 10928)                        transactions to CSA recordkeeping and reporting requirements. Domestic and import transactions involving chemical mixtures containing acetone, ethyl ether, 2-butanone and toluene are not subject to the following information collections: DEA information collection 1117-0023: Import/Export Declaration for List I and List II Chemicals [imports only]; and DEA information collection 1117-0029: Annual Reporting Requirement for Manufacturers of Listed Chemicals.
