is amended— 
(1) in the subsection heading, by inserting ‘‘AND 
MERCURY COMPOUNDS’’ after ‘‘MERCURY’’; and 
(2) by inserting after paragraph (2) the fol-

‘‘(3) PROHIBITION ON EXPORT OF CERTAIN MER-
CURY COMPOUNDS.— 
‘‘(A) IN
GENERAL.—Effective January 1, 
2020, the export of the following mercury com-
pounds is prohibited: 
‘‘(i) Mercury (I) chloride or calomel. 
‘‘(ii) Mercury (II) oxide. 
‘‘(iii) Mercury (II) sulfate. 
‘‘(iv) Mercury (II) nitrate. 
‘‘(v) Cinnabar or mercury sulphide. 
‘‘(vi) Any mercury compound that the 
Administrator, at the discretion of the Ad-
ministrator, adds to the list by rule, on de-
termining that exporting that mercury com-
pound for the purpose of regenerating ele-
mental mercury is technically feasible.

days after the date of enactment of the Frank R.

Act, and as appropriate thereafter, the Adminis-
trator shall publish in the Federal Register a list 
of the mercury compounds that are prohibited 
from export under this paragraph. 
‘‘(C) PETITION.—Any person may petition 
the Administrator to add to the list of mercury 
compounds prohibited from export. 
‘‘(D) 
ENVIRONMENTALLY
SOUND
DIS-
POSAL.—This paragraph does not prohibit the 
export of mercury (I) chloride or calomel for en-
vironmentally sound disposal to member coun-
tries of the Organization for Economic Coopera-
tion and Development, on the condition that no 
mercury or mercury compounds are to be recov-
ered, recycled, or reclaimed for use, or directly 
reused. 
‘‘(E) REPORT.—Not later than 5 years after 
the date of enactment of the Frank R. Lauten-
berg Chemical Safety for the 21st Century Act, 
the Administrator shall evaluate any exports of 
calomel for disposal that occurred since that date 
of enactment and shall submit to Congress a re-
port that contains the following: 
‘‘(i) volumes and sources of calomel ex-
ported for disposal;
201 
† HR 2576 EAS 
‘‘(ii) receiving countries of such ex-
ports; 
‘‘(iii) methods of disposal used; 
‘‘(iv) issues, if any, presented by the 
export of calomel; 
‘‘(v) evaluation of calomel management 
options in the United States, if any, that 
are commercially available and comparable 
in cost and efficacy to methods being uti-
lized in the receiving countries; and 
‘‘(vi) a recommendation regarding 
whether Congress should further limit or 
prohibit the export of calomel for disposal. 
‘‘(F) EFFECT ON OTHER LAW.—Nothing in 
this paragraph shall be construed to affect the 
authority of the Administrator under Solid 
Waste Disposal Act (42 U.S.C. 6901 et seq.).’’. 
SEC. 30. TREVOR’S LAW. 
(a) PURPOSES.—The purposes of this section are— 
(1) to provide the appropriate Federal agencies 
with the authority to help conduct investigations into 
potential cancer clusters; 
(2) to ensure that Federal agencies have the au-
thority to undertake actions to help address cancer
202 
† HR 2576 EAS 
clusters and factors that may contribute to the cre-
ation of potential cancer clusters; and 
(3) to enable Federal agencies to coordinate with 
other Federal, State, and local agencies, institutes of 
higher education, and the public in investigating and 
addressing cancer clusters. 
(b) DESIGNATION AND INVESTIGATION OF POTENTIAL 
CANCER CLUSTERS.—Part P of title III of the Public 
Health Service Act (42 U.S.C. 280g et seq.) is amended by 
adding at the end the following: 
‘‘SEC. 399V–6. DESIGNATION AND INVESTIGATION OF PO-
TENTIAL CANCER CLUSTERS. 
‘‘(a) DEFINITIONS.—In this section: 
‘‘(1) CANCER CLUSTER.—The term ‘cancer clus-
ter’ means the incidence of a particular cancer within 
a population group, a geographical area, or a period 
of time that is greater than expected for such group, 
area, or period. 
‘‘(2) PARTICULAR
CANCER.—The term ‘par-
ticular cancer’ means one specific type of cancer or 
a type of cancers scientifically proven to have the 
same cause. 
‘‘(3) POPULATION GROUP.—The term ‘population 
group’ means a group, for purposes of calculating
203 
† HR 2576 EAS 
cancer rates, defined by factors such as race, eth-
nicity, age, or gender. 
‘‘(b) CRITERIA FOR DESIGNATION OF POTENTIAL CAN-
CER CLUSTERS.— 
‘‘(1) DEVELOPMENT
OF
CRITERIA.—The Sec-
retary shall develop criteria for the designation of po-
tential cancer clusters. 
‘‘(2) REQUIREMENTS.—The criteria developed 
under paragraph (1) shall consider, as appropriate— 
‘‘(A) a standard for cancer cluster identi-
fication and reporting protocols used to deter-
mine when cancer incidence is greater than 
would be typically observed; 
‘‘(B) scientific screening standards that en-
sure that a cluster of a particular cancer in-
volves the same type of cancer, or types of can-
cers; 
‘‘(C) the population in which the cluster of 
a particular cancer occurs by factors such as 
race, ethnicity, age, and gender, for purposes of 
calculating cancer rates; 
‘‘(D) the boundaries of a geographic area in 
which a cluster of a particular cancer occurs so 
as not to create or obscure a potential cluster by 
selection of a specific area; and
204 
† HR 2576 EAS 
‘‘(E) the time period over which the number 
of cases of a particular cancer, or the calculation 
of an expected number of cases, occurs. 
‘‘(c) GUIDELINES FOR INVESTIGATION OF POTENTIAL 
CANCER CLUSTERS.—The Secretary, in consultation with 
the Council of State and Territorial Epidemiologists and 
representatives of State and local health departments, shall 
develop, publish, and periodically update guidelines for in-
vestigating potential cancer clusters. The guidelines shall— 
‘‘(1) require that investigations of cancer clus-
ters— 
‘‘(A) use the criteria developed under sub-
section (b); 
‘‘(B) use the best available science; and 
‘‘(C) rely on a weight of the scientific evi-
dence; 
‘‘(2) provide standardized methods of reviewing 
and categorizing data, including from health surveil-
lance systems and reports of potential cancer clusters; 
and 
‘‘(3) provide guidance for using appropriate epi-
demiological and other approaches for investigations. 
‘‘(d) INVESTIGATION OF CANCER CLUSTERS.— 
‘‘(1) SECRETARY DISCRETION.—The Secretary—

extent practicable, upon receiving a request to inves-
tigate a potential cancer cluster from a State or local 
health authority; 
‘‘(2) maintain staff expertise in epidemiology, 
toxicology, data analysis, environmental health and 
cancer surveillance, exposure assessment, pediatric 
health, pollution control, community outreach, health 
education, laboratory sampling and analysis, spatial 
mapping, and informatics; 
‘‘(3) consult with community members as inves-
tigations into potential cancer clusters are conducted, 
as the Secretary determines appropriate; 
‘‘(4) collect, store, and disseminate reports on in-
vestigations of potential cancer clusters, the possible 
causes of such clusters, and the actions taken to ad-
dress such clusters; and 
‘‘(5) provide technical assistance for inves-
tigating cancer clusters to State and local health de-
partments through existing programs, such as the 
Epi-Aids program of the Centers for Disease Control 
and Prevention and the Assessments of Chemical Ex-
