Download as PDF daltland on DSKBBV9HB2PROD with NOTICES 50364 Federal Register / Vol. 83, No. 194 / Friday, October 5, 2018 / Notices effect of the dumping on esthetic, recreational, or economic values; landbased alternatives to ocean dumping; and the adverse effects of the dumping on other uses of the ocean. The Ocean Dumping Criteria are codified in 40 CFR parts 227–228. To meet U.S. reporting obligation under the London Convention, an international treaty on ocean dumping, EPA also reports some of this information in the annual United States Ocean Dumping Report. EPA uses ocean dumping information to make decisions regarding whether issue, deny, as well as to impose conditions on ocean dumping permits issued by EPA in order to ensure consistency with the Ocean Dumping Criteria. EPA uses monitoring and reporting data from permittees to assess compliance with ocean dumping permits, including associated monitoring activities. Form numbers: None. Respondents/affected entities: Respondents/affected entities may include any private person or entity, or state, local, or foreign governments. Respondent’s obligation to respond: Required to obtain or retain a benefit, specifically permit authorization and/or compliance with permits required under MPRSA sections 102 and 104, 33 U.S.C. 1402 & 1404, and implementing regulations at 40 CFR parts 220–229. Estimated number of respondents: 2,768 respondents per year. Frequency of response: The frequency of response varies for application and reporting requirements for different permits. Other than the general permit for transportation and disposal of vessels, response is required once for each permit application, whether a single notification to EPA or a permit application. Depending on the type of MPRSA permit, a permit application would be required prior to expiration if the permittee seeks re-issuance: General permit (once every seven years), special permit (once every three years), and research permit (once every 18 months). Total estimated burden: The public reporting and recordkeeping burdens for this collection of information are estimated to be 3,497 hours per year. Burden is defined at 5 CFR 1320.3(b). Total estimated cost: Annual costs are estimated to be $380,376, which includes $184,503 for labor and $195,874 for capital or operation & maintenance costs. Changes in estimates: There is no significant increase in the burden. There is an increase of 1 hour in the total estimated respondent burden compared with the ICR currently approved by OMB. This increase is due to a change in the program requirements and VerDate Sep<11>2014 17:11 Oct 04, 2018 Jkt 247001 reflects updated reporting burden estimates. Specifically, since the issuance of the current ICR, EPA issued an additional general permit under the MPRSA for the transport and disposal of marine mammal carcasses in ocean waters under specified conditions. The estimates in the supporting information reflect the increase associated with the general permit, which was published in the Federal Register on December 6, 2016 [81 FR 87928].

SUPPLEMENTARY INFORMATION: I. General Information A. Does this action apply to me? This notice does not impose any requirements on anyone; it only requests nominations for the drinking water Contaminant Candidate List (CCL) and provides information on how the public can submit nominations to the EPA. B. How can I get copies of this document and other related information? The EPA has established a docket for this action under Docket ID No. EPA– HQ–OW–2018–0594. Publicly available docket materials are accessible either electronically through http:// www.regulations.gov or in hard copy at the Water Docket in the EPA Docket Center (see the ADDRESSES section of this notice). II. Background A. What is the CCL? The CCL is a list of contaminants that are currently not subject to any proposed or promulgated national primary drinking water regulations, that are known or anticipated to occur in public water systems, and which may require regulation under the Safe E:\FR\FM\05OCN1.SGM 05OCN1 Federal Register / Vol. 83, No. 194 / Friday, October 5, 2018 / Notices Drinking Water Act (SDWA). The EPA uses this list of unregulated contaminants to prioritize research and data collection efforts to help the Agency determine whether to regulate a specific contaminant. The SDWA requires that the EPA publish the CCL every five years (SWDA § 1412(b)(1)). The EPA is also required to consult with the scientific community, including the Science Advisory Board, and provide notice and opportunity for public comment prior to publication of the final CCL. The SDWA also requires the EPA to determine whether to regulate at least five contaminants from the CCL every five years (SWDA § 1412(b)(1)). To regulate a contaminant, the SDWA specifies the EPA must determine that: 1. The contaminant may have an adverse effect on the health of persons; 2. The contaminant is known to occur, or there is a substantial likelihood that the contaminant will occur, in public water systems with a frequency and at levels of public health concern; and 3. In the sole judgment of the Administrator, regulation of such contaminant presents meaningful opportunity for health risk reduction for persons served by public water systems. daltland on DSKBBV9HB2PROD with NOTICES B. What contaminants were listed on the previous Contaminant Candidate List? The fourth CCL (CCL 4) was published on November 17, 2016 (81 FR 81099). CCL 4 included 97 chemicals or chemical groups and 12 microbial contaminants. The list includes, among others, chemicals used in commerce, pesticides, biological toxins, disinfection byproducts, pharmaceuticals, and waterborne pathogens. The list of contaminants included on CCL 4, and other information regarding the CCL, can be found on the internet at https:// www.epa.gov/ccl and in the Federal Register notice for the final CCL 4 (81 FR 81099, November 17, 2016). C. Why is the EPA soliciting contaminant nominations? The EPA is conducting an evaluation of potential contaminants for inclusion on the draft CCL 5. The EPA is requesting public nominations for contaminants that are not currently regulated, to ensure that contaminants that may not be typically identified as part of the EPA’s CCL process are considered. The National Academy of Sciences (NAS, 2001) and National Drinking Water Advisory Council (NDWAC, 2004) recommended to the EPA that the CCL be a data-driven, stepwise approach to classifying VerDate Sep<11>2014 17:11 Oct 04, 2018 Jkt 247001 contaminants. These experts also recognized the importance of providing an additional pathway for the public to identify new and emerging contaminants for the EPA to further evaluate. A public nomination process allows the EPA to consider new and emerging contaminants that might not otherwise be considered because new information may exist that the EPA is unaware of and/or the information may not have been widely reported or recorded. III. The EPA CCL Nomination Process This contaminant nomination process is the first opportunity for the public to make nominations for contaminants to be considered for the CCL 5. The EPA will also accept nominations during the notice and comment period following the EPA’s publication of the draft CCL 5 in the Federal Register. A. How can stakeholders, agencies, industry, and the public nominate contaminants for the CCL 5? Interested parties can nominate chemicals, microbes, or other materials for consideration on the CCL 5 by sending information electronically through http://www.regulations.gov, by mail, or by hand delivery (see the ADDRESSES section of this notice). Do not submit confidential business information (CBI) to the EPA through http://www.regulations.gov or email. Submit comments that contain CBI only by mail or hand delivery, and clearly mark the part of or all the information that you claim to be CBI. In addition to one complete version of the comment that includes information claimed as CBI, a non-CBI copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in the Code of Federal Regulations at 40 CFR part 2. When submitting a nomination, it is preferred that the nominators include a name, affiliation, phone number, mailing address, and email address; however, this information is not required and nominations can be submitted anonymously. The nominator should also address the following questions for each contaminant nominated to the CCL: 1. What is the contaminant’s name, CAS number, and/or common synonym (if applicable)? Please do not nominate a contaminant that is already subject to a national primary drinking water regulation. 2. What are the data that you believe support the conclusion that the PO 00000 Frm 00035 Fmt 4703 Sfmt 4703 50365 contaminant is known or anticipated to occur in public water systems? For example, provide information that shows measured occurrence of the contaminant in drinking water or measured occurrence in sources of drinking water or provide information that shows the contaminant is released in the environment or is manufactured in large quantities and has a potential for contaminating sources of drinking water. Please provide the source of this information with complete citations for published information (i.e., author(s), title, journal, and date) or contact information for the primary investigator. 3. What are the data that you believe support the conclusion that the contaminant may require regulation? For example, provide information that shows the contaminant may have an adverse health effect on the general population or that the contaminant is potentially harmful to subgroups that comprise a meaningful portion of the population (such as children, pregnant women, the elderly, individuals with a history of serious illness, or others). Please provide the source of this information with complete citations for published information (i.e., author(s), title, journal, and date) or contact information for the primary investigator. B. How do I submit nominations in hard copy? You may submit nominations by mail or hand delivery. To allow full consideration of your nomination, please ensure that your nominations are received or postmarked by midnight December 4, 2018. The address for submittal of nominations by mail or hand delivery is listed in the ADDRESSES section of this document. C. What will happen to my nominations after I submit them? The EPA will evaluate the information available for the nominated contaminants to determine the appropriateness of inclusion on the CCL 5. The EPA does not intend to respond to the nominations directly or individually. The EPA will summarize the nominations received when the draft CCL 5 list is published in the Federal Register. IV.

SUPPLEMENTARY INFORMATION: 

I. General Information

A. Does this action apply to me?

    This notice does not impose any requirements on anyone; it only 
requests nominations for the drinking water Contaminant Candidate List 
(CCL) and provides information on how the public can submit nominations 
to the EPA.

B. How can I get copies of this document and other related information?

    The EPA has established a docket for this action under Docket ID 
No. EPA-HQ-OW-2018-0594. Publicly available docket materials are 
accessible either electronically through http://www.regulations.gov or 
in hard copy at the Water Docket in the EPA Docket Center (see the 
ADDRESSES section of this notice).

II. Background

A. What is the CCL?

    The CCL is a list of contaminants that are currently not subject to 
any proposed or promulgated national primary drinking water 
regulations, that are known or anticipated to occur in public water 
systems, and which may require regulation under the Safe

[[Page 50365]]

Drinking Water Act (SDWA). The EPA uses this list of unregulated 
contaminants to prioritize research and data collection efforts to help 
the Agency determine whether to regulate a specific contaminant. The 
SDWA requires that the EPA publish the CCL every five years (SWDA Sec.  
1412(b)(1)). The EPA is also required to consult with the scientific 
community, including the Science Advisory Board, and provide notice and 
opportunity for public comment prior to publication of the final CCL.
    The SDWA also requires the EPA to determine whether to regulate at 
least five contaminants from the CCL every five years (SWDA Sec.  
1412(b)(1)). To regulate a contaminant, the SDWA specifies the EPA must 
determine that:
    1. The contaminant may have an adverse effect on the health of 
persons;
    2. The contaminant is known to occur, or there is a substantial 
likelihood that the contaminant will occur, in public water systems 
with a frequency and at levels of public health concern; and
    3. In the sole judgment of the Administrator, regulation of such 
contaminant presents meaningful opportunity for health risk reduction 
for persons served by public water systems.

B. What contaminants were listed on the previous Contaminant Candidate 
List?

    The fourth CCL (CCL 4) was published on November 17, 2016 (81 FR 
81099). CCL 4 included 97 chemicals or chemical groups and 12 microbial 
contaminants. The list includes, among others, chemicals used in 
commerce, pesticides, biological toxins, disinfection byproducts, 
pharmaceuticals, and waterborne pathogens. The list of contaminants 
included on CCL 4, and other information regarding the CCL, can be 
found on the internet at https://www.epa.gov/ccl and in the Federal 
Register notice for the final CCL 4 (81 FR 81099, November 17, 2016).

C. Why is the EPA soliciting contaminant nominations?

    The EPA is conducting an evaluation of potential contaminants for 
inclusion on the draft CCL 5. The EPA is requesting public nominations 
for contaminants that are not currently regulated, to ensure that 
contaminants that may not be typically identified as part of the EPA's 
CCL process are considered. The National Academy of Sciences (NAS, 
2001) and National Drinking Water Advisory Council (NDWAC, 2004) 
recommended to the EPA that the CCL be a data-driven, step-wise 
approach to classifying contaminants. These experts also recognized the 
importance of providing an additional pathway for the public to 
identify new and emerging contaminants for the EPA to further evaluate. 
A public nomination process allows the EPA to consider new and emerging 
contaminants that might not otherwise be considered because new 
information may exist that the EPA is unaware of and/or the information 
may not have been widely reported or recorded.

III. The EPA CCL Nomination Process

    This contaminant nomination process is the first opportunity for 
the public to make nominations for contaminants to be considered for 
the CCL 5. The EPA will also accept nominations during the notice and 
comment period following the EPA's publication of the draft CCL 5 in 
the Federal Register.

A. How can stakeholders, agencies, industry, and the public nominate 
contaminants for the CCL 5?

    Interested parties can nominate chemicals, microbes, or other 
materials for consideration on the CCL 5 by sending information 
electronically through http://www.regulations.gov, by mail, or by hand 
delivery (see the ADDRESSES section of this notice). Do not submit 
confidential business information (CBI) to the EPA through http://www.regulations.gov or email. Submit comments that contain CBI only by 
mail or hand delivery, and clearly mark the part of or all the 
information that you claim to be CBI. In addition to one complete 
version of the comment that includes information claimed as CBI, a non-
CBI copy of the comment that does not contain the information claimed 
as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in the Code of Federal Regulations at 40 CFR part 
2.
    When submitting a nomination, it is preferred that the nominators 
include a name, affiliation, phone number, mailing address, and email 
address; however, this information is not required and nominations can 
be submitted anonymously. The nominator should also address the 
following questions for each contaminant nominated to the CCL:
    1. What is the contaminant's name, CAS number, and/or common 
synonym (if applicable)? Please do not nominate a contaminant that is 
already subject to a national primary drinking water regulation.
    2. What are the data that you believe support the conclusion that 
the contaminant is known or anticipated to occur in public water 
systems? For example, provide information that shows measured 
occurrence of the contaminant in drinking water or measured occurrence 
in sources of drinking water or provide information that shows the 
contaminant is released in the environment or is manufactured in large 
quantities and has a potential for contaminating sources of drinking 
water. Please provide the source of this information with complete 
citations for published information (i.e., author(s), title, journal, 
and date) or contact information for the primary investigator.
    3. What are the data that you believe support the conclusion that 
the contaminant may require regulation? For example, provide 
information that shows the contaminant may have an adverse health 
effect on the general population or that the contaminant is potentially 
harmful to subgroups that comprise a meaningful portion of the 
population (such as children, pregnant women, the elderly, individuals 
with a history of serious illness, or others). Please provide the 
source of this information with complete citations for published 
information (i.e., author(s), title, journal, and date) or contact 
information for the primary investigator.

B. How do I submit nominations in hard copy?

    You may submit nominations by mail or hand delivery. To allow full 
consideration of your nomination, please ensure that your nominations 
are received or postmarked by midnight December 4, 2018. The address 
for submittal of nominations by mail or hand delivery is listed in the 
ADDRESSES section of this document.

C. What will happen to my nominations after I submit them?

    The EPA will evaluate the information available for the nominated 
contaminants to determine the appropriateness of inclusion on the CCL 
5. The EPA does not intend to respond to the nominations directly or 
individually. The EPA will summarize the nominations received when the 
draft CCL 5 list is published in the Federal Register.
