The Petroleum Restoration Program (PRP) of the Florida Department of Environmental
Protection (DEP or Department) has reviewed the Low Score Site Initiative (LSSI) Site Assessment
Report (SAR)/Conditional No Further Action (NFA) Proposal, dated and received October 27, 2017, and
the Monitoring Well Abandonment Report dated and received January 24, 2019, for Firestone #19F5
(DBA Tire Plus Total Car Care) for the petroleum discharge referenced above. Maps showing the
location of the Firestone #19F5 (DBA Tire Plus Total Car Care) and the location of the "contaminated
site" (i.e., contaminant plume) for which this Order is being issued are attached as Exhibits 1 and 2 and
are incorporated by reference herein. Failure to comply with the provisions of this order is a violation of
section 376.302, Florida Statutes (F.S.). The contaminated site includes the following parcels or parts of
parcels 2601 US 19 N (AKA 2610 Countryside Blvd.) Clearwater, Pinellas County, Parcel Identification
Number; 30-28-16-68305-000-0012, collectively referred to as the property.
The contamination, which resulted from a discharge that was discovered on December 22, 1988,
consisted of petroleum and petroleum products. The discharge resulted from petroleum discharge
associated with petroleum storage systems. The Conditional NFA Proposal is supported by earlier
submittals, prepared pursuant to the requirements of Chapter 62-780, Florida Administrative Code
(F.A.C.), which can be found in the Department's document repository, Oculus at
http://depedms.dep.state.fl.us/Oculus/.

Based on the documentation submitted with the Conditional NFA Proposal and other documents,
DEP has reasonable assurance that that the criteria in Chapter 62-780.680(3), F.A.C. has been met,
including the commitments set forth in the technical submittals with respect to the establishment of
acceptable Alternative Cleanup Target Levels (ACTLs). The documents attached (Exhibit 4) for soil
contaminants remaining at the contaminated site, detail the conditions for this site. Therefore, you have
satisfied the site rehabilitation requirements for the contaminated site and are released from any further
obligation to conduct site rehabilitation at the contaminated site, except as set forth below. See attached
table (Exhibit 3), incorporated by reference herein, which includes information regarding the
contaminm* ts; affected media; applicable cleanup target levels; and the ACTLs established for the
contaminated site that is the subject of this Order.
Future owners and users of the property should be made aware of the existence and contents of
this Order. Additionally, information about the contaminated site will be maintained on the
Institutional Controls Registry at httpsi/fjpridadep.gov/waste/waste/content/institutional-
controls-registry-guidance
Further, in accordance with Section 376.30701(4), F.S., upon completion of site rehabilitation,
additional site rehabilitation is not required unless it is demonstrated that:
(a)
(b)
(c)
Fraud was committed in demonstrating site conditions or completion of site rehabilitation;
New information confirms the existence of an area of previously unknown contamination
which exceeds the site-specific rehabilitation levels established in accordance with Section
376.30701(2), F.S., or which otherwise poses the threat of real and substantial harm to
public health, safety, or the environment;
The remediation efforts failed to achieve the site rehabilitation criteria established under
this section;
(d) The level of risk is increased beyond the acceptable risk established under Section
376.30701(2), F.S., due to substantial changes in exposure conditions, such as a change in
land use from nonresidential to residential use. Any person who changes the land use of the
site, thereby causing the level of risk to increase beyond the acceptable risk level, may be
required by DEP to undertake additional remediation measures to ensure that human health,
public safety, and the environment are protected consistent with Section 376.30701, F.S.;
or
(e) A new discharge of pollutants or hazardous substances occurs at the site subsequent to the
issuance of this Order
NOTICE OF RIGHTS
This action is final and effective on the date filed with the Clerk of the Department unless a petition for an
administrative hearing is timely filed under Sections 120.569 and 120.57, F.S., before the deadline for filing a
petition. On the filing of a timely and sufficient petition, this action will not be final and effective until a
subsequent order of the Department. Because the administrative hearing process is designed to formulate final
agency action, the subsequent order may modify or take a different position than this action.

Re: Review of benzo(a)pyrene ASCTLs In letters dated February 10 and May 11, 2017
Dear Dr. Liehr:
At your request, we have reviewed the benzo(a)pyrene (BaP) toxic equivalents (TEQs)
alternative soil cleanup target levels (ASCTLs) calculated in a letter addressed to you dated
February 10, 2017 and In the draft update to the Chapter 62-777, Florida Administrative Code
(F.A.C.) table submitted May 11, 2017. This letter explains how different BaP ASCTLs were
derived in the two letters. Additionally, ft evaluates the effect of incorporating the age dependent
adjustment factor (ADAF) in the BaP TEQ calculation as recommended by the U.S. Environmental
Protection Agency (USEPA).
The February 10, 2017 letter contained a derivation of a residential ASCTL for BaP TEQs
of 1.5 mg/kg and a commercial/industrial ASCTL of 6.4 mg/kg. The derivation of these values
included use of updated toxicity values and exposure assumptions. The updated toxicity values
were taken from the USEPA's Integrated Risk Information System (IRIS) and Include a BaP oral
cancer slope factor of 1E+00 per mg/kg -d and an inhalation unit risk of 6E-04 per mg/m3 (USEPA,
2017). Updated exposure assumptions were taken from OSWER Directive 9200.1-120 (2014).
Assumptions not included In the OSWER Directive were taken from Chapter 82-777, FA.C. The
equation used to calculate the February 10, 2017 ASCTLs was taken from Figure 4 of Chapter
62.777, F.A.C. However, the dermal pathway was inadvertently excluded from the calculation.
Therefore, these ASCTLs do not include dermal exposure. Exclusion of the dermal pathway is
not consistent with Chapter 82-777, FAC, or Chapter 82-780, F.A.C., with regard to the
derivation of alternative cleanup target levels. Although the USEPA currently excludes dermal
exposure for the indoor worker scenario, this Is not appropriate for an outdoor worker or a resident.
The draft Chapter 82-777, F.A.C. Table 2 update dated May 11, 2017 Includes a
residential SCTL for BaP TEQs of 1 mg/kg and a commerclaiindustrlal SCTL of 3.1 mg/kg. The
assumptions and toxicity values utilized In the calculation of these SCTLs were identical to those
used In the ASCTLs for BaP TEQs in the letter dated February 10, 2017 (Figure 1 and Table 1).
However, this calculation Included the dermal pathway. Additionally, between the February 10,
2017 letter and the May 11, 2017 letter, the dermal absorption for BaP was updated from the
default value of 0.1 to the chemical -specific value of 0.13 listed In the USEPA regional screening
level (RSL) tables (hitpsl/www.epe.gov/risk/regional-screening-levels-rale-generic-tabies-june-
The Foundation for The Gator Nation
An Equal opporhmNy 6rotLtut on
2017). The inclusion of the dermal pathway and update to the dermal absorption results in the
difference in BaP TEQ criteria between these two letters. The SCTLs for BaP TEQs listed In the
draft Table 2 update (1 mg/kg residential and 3.1 mg/kg commercial/industrial) reflect, the most
current assumptions and toxicity values and should be used in place of the February 10, 2017
ASCTLs. The February 10, 2017 ASCTLs can .no longer be supported by current parameter
values or as meeting Florida's regulatory requirements for the default exposure scenarios.
An additional issue to consider Is the Inclusion of age -dependent adjustment factors
(ADAFs) .for mutagenic carcinogens, which include BaP, and other carcinogenic polycyclic
aromatic hydrocarbons (PAHs). Current. toxicity estimates based on an average daily exposure
do not include the potential for higher cancer risk during early lifestages (i.e., infancy through mid-
teens). ADAFs were developed by the USEPA in 2005 to address such childhood exposures.
ADAFs are factors that take Into account the greatersusceptibility of children to-. mutagenic
carcinogens by adjusting the toxicity value for early lifestages. The USEPA analyzed repeated
dose studies for early postnatal, juvenile, and adults on 67 different carcinogenic chemicals (or
mixtures). They concluded that early lifestage exposure to carcinogenic chemicals with a
mutagenic mode of action leads to increased tumor inddence compared with adult exposures of
similar duration and dose (USEPA, 2005). Early lifestage susceptibility is not only seen in animal
studies. Evidence of Increased susceptibility in childhood to carcinogens is also apparent in
clinical and epidemiological cases (e.g., diethylstilbestrol, radioactive iodine, Immunosuppressive
drugs) (WDOE, 2010).
The ten -fold adjustment that is applied to toxicity values for 0-2 year olds represents the
weighted geometric mean tumor incidence ratio between juvenile and adult exposures in repeated
dosing studies (USEPA, 2005). The three -fold toxicity adjustment for ages 2 through X16 years
old represents a midpoint between the toxicity adjustment for adults (1) and Juveniles (10) on a
logarithmic scale. Consideration of early lifestage susceptibility in risk assessment is supported
by the Science Advisory Board (USEPA, 2011) and the National Research Council (NRC, 2008).
Currently 46% of 40 states surveyed utilize the ADAF (University of Florida survey presented to
the Contaminated Media Forum). This number Increases to 65% for states that have updated
their soil equations in the last 7 years. ADAFs are not currently included In Chapter 62-777,
F.A.C. equations. If the ADAF is not used to account for the increased susceptibility of early
lifestages to mutagens, risks to children may be underestimated. The inclusion of ADAFs would
lower the BaP SCTL for residents. Although the exact amount the SCTL would be lowered Is
determined by the equation used, current Chapter 62-777, F.A.C. equations would result in
lowering the mutagenic SCTLs by a factor of 2.4. However, it would not affect SCTLs for
scenarios that do not include children (e.g., commercial/industrial worker, construction worker,
adult residential community).
Please let us know if you have any questions regarding this review.
Sincerely,
,Z./fze
