Option 2 for Sec.  63.647; Option 1 Would Not Revise Sec.  63.647

    8. Section 63.647 is amended by adding paragraph (d) to read as
follows:

Sec.  63.647  Wastewater provisions.

* * * * *
    (d) On and after the compliance date specified in Sec.
63.640(h)(7), the owner or operator of an enhanced biodegradation unit
(EBU) that receives a Group 1 wastewater stream from a petroleum
refinery shall comply with the requirements in paragraphs (d)(1)
through (6) of this section. The provisions in Sec.
61.348(b)(2)(ii)(B) for the recommended range for the food-to-
microorganism ratio, the mixed liquor suspended solids concentration,
and residence time do not apply, and the requirements in Sec. Sec.
61.348(b)(2)(i), 61.354(b)(2), and 61.355(k)(4)(i) for monitoring the
benzene concentration at the inlet to the EBU and maintaining it below
10 parts per million by weight (ppmw) do not apply.
    (1) The fraction biodegraded of benzene in each EBU shall be 90
percent or greater.
    (2) The mixed liquor volatile suspended solids (MLVSS)
concentration shall not fall below the operating limit established
during the initial performance test.
    (3) The food-to-microorganism ratio shall not exceed the operating
limit established during the initial performance test.

    (i) Food can be measured as either grams per liter (g/l) of 5-day
biological oxygen demand (BOD5) or g/l of chemical oxygen
demand (COD), but you must use the same measure used to develop your
operating limit.
    (ii) Determine the food-to-microorganism ratio operating limit
using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TP04SE07.003

Where:

BOD5 = 5-day biological oxygen demand or chemical oxygen
demand of EBU influent wastewater (g/l = kg/m\3\);
Qin = Influent wastewater volumetric flow rate to the EBU
(m\3\/day);
[MLVSS] = Concentration of mixed liquor volatile suspended solids
(g/l = kg/m\3\); and
VEBU = Average volume of wastewater in the EBU during
normal process operations (m\3\).

    (4) The owner or operator shall conduct an initial performance test
to demonstrate compliance with the treatment efficiency standard of
each EBU using the following procedures:
    (i) Determine the fraction biodegraded of benzene as determined
according to the procedures in appendix C to part 63 (Determination of
the Fraction Biodegraded (Fbio) in a Biological Treatment
Unit).
    (ii) Use the multiple zone concentration method with separate
``inlet'' zones for each inlet location containing an applicable
benzene waste stream. The inlet zone is defined as the depth of the EBU
times the 100 square foot area surrounding each benzene wastewater
inlet.
    (iii) The remainder of the EBU may be modeled as a single zone or
multiple zones depending on the mixing zones present in the EBU as
described in appendix C to part 63.
    (iv) The volume-weighted average MLVSS concentration used in the
multiple zone Fbio test must be used as the operating limit
for MLVSS. The volume-weighted average food-to-microorganism ratio used
in the multiple zone Fbio test must be used as the operating
limit for the food-to-microorganism ratio.
    (5) Measure the MLVSS in the EBU no less frequently than once per
week using Method 2540 (incorporated by reference--see Sec.  63.14);
and
    (6) Measure the EBU influent biological oxygen demand (BOD) using
Method 5210 (incorporated by reference--see Sec.  63.14) or the COD
MLVSS using Method 5220 (incorporated by reference--see Sec.  63.14) in
the EBU no less frequently than once per week. Calculate the food-to-
microorganism ratio once a week using Equation 1 of this section and
record the results.
    9. Section 63.650 is amended by revising paragraph (a) to read as
follows.

Sec.  63.650  Gasoline loading rack provisions.

    (a) Except as provided in paragraphs (b) through (c) of this
section, each owner or operator of a Group 1 gasoline loading rack
classified under Standard Industrial Classification code 2911 located
within a contiguous area and under common control with a petroleum
refinery shall comply with subpart R, Sec. Sec.  63.421, 63.422(a)
through (c), 63.425(a) through (c), 63.425(e) through (h), 63.427(a)

Option 1 for Sec.  63.654

    12. Section 63.654 is added to read as follows:

Sec.  63.654  Cooling tower systems.

    (a) On and after the compliance date specified in Sec.
63.650(h)(8), the owner or operator of an existing source shall monitor
each cooling tower system subject to this subpart to detect and repair
leaks of organic HAP into the cooling water. The owner or operator may
elect to monitor the total organic HAP listed in Table 1 of this
subpart on a quarterly basis according to the requirements in
paragraphs (a)(1) of this section or monitor chemical usage or other
surrogates according to the requirements in paragraph (a)(2) of this
section.
    (1) The owner or operator shall conduct quarterly monitoring of
total organic HAP listed in Table 1 of this subpart according to the
methods and procedures in paragraphs (a)(1)(i) through (iii) of this
section.
    (i) Collect a water sample from each cooler water return line(s)
prior to air stripping or exposure to air. You must collect each sample
using the sampling procedures in Sec.  61.355(c)(3) of the National
Emission Standard for Benzene Waste Operations.
    (ii) Analyze each sample using EPA Method 8260B (incorporated by
reference--see Sec.  63.14). Determine the total organic HAP
concentration as the sum of the individual HAP concentrations of the
HAP listed in Table 1 of this subpart.
    (iii) If the total organic HAP concentration exceeds 1 part per
million by weight (ppmw), a leak is detected.
    (2) The owner or operator shall monitor chlorine or bromine usage
at least once each day, free chlorine at least twice each day,
oxidation reduction potential (ORP) at least six times per day,
hydrocarbons (using an online analyzer) at least twice each day, or
volatile organic compounds (VOC) El Paso at least once each month
according to the procedures in paragraphs (a)(2)(i) through (iii) of
this section.
    (i) Conduct an initial analysis of the cooling water using EPA
Method 8260B (incorporated by reference--see Sec.  63.14) to
demonstrate that the total organic HAP concentration is less than 1
ppmw.
    (ii) Establish operating limits for the parameters to be monitored.
You must identify the parameters to be monitored and the established
operating limits in your Notification of Compliance Status and written
monitoring plan.
    (iii) If the monitored operating parameter exceeds the operating
limit, you must sample the cooling water to determine the total organic
HAP concentration. If the total organic HAP concentration exceeds 1
ppmw, a leak is detected.
    (b) On and after the compliance date specified in Sec.
63.650(h)(8), the owner or operator of a new source shall monitor the
concentration of HAP from each cooling tower system subject to this
subpart on a quarterly basis to identify and repair any leak with a
potential mass leak rate of 10 pounds per day (lb/day) or greater of
any single HAP listed in Table 1 of this subpart or 100 lb/day or
greater of total HAP listed in Table 1 of this subpart. A heat exchange
system may consist of an entire heat exchange system or a combination
of heat exchangers such that, based on the rate of cooling water and
the sensitivity of the test method, a leak of 10 lb/day or greater of
any single HAP listed in Table 1 of this subpart or 100 lb/day or
greater of total HAP would be detected. The owner or operator shall
conduct the quarterly monitoring according to the methods and
procedures in paragraphs (a)(1) through (4) of this section.
    (1) Collect a water sample from each cooler water return line(s)
prior to air stripping or exposure to air. You must collect each sample
using the sampling procedures in Sec.  61.355(c)(3) of the National
Emission Standard for Benzene Waste Operations.
    (2) Analyze each sample using EPA Method 8260B (incorporated by
reference--see Sec.  63.14). Determine the total HAP concentration as
the sum of the individual HAP concentrations of the HAP listed in Table
1 of this subpart.
    (3) Calculate and record the potential mass leak rate using
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TP04SE07.004

Where:

L = Potential mass leak rate of HAP (lb/day);
0.012 = Constant for unit conversion (lb/gallon x minutes/day x part
per million parts);
CHAP = Concentration of individual or total organic HAP
in the cooling tower water prior to exposure to the air (ppmw); and
QCT = Volumetric flow rate of cooling water to the
cooling tower (gallons per minute).
    (4) If the results of Equation 1 of this section indicate a leak
with a mass leak rate of 10 lb/day of any single HAP or 100 lb/day of
total HAP per day or greater, a leak is detected.
    (c) If a leak is detected, the owner or operator must identify the
source of the leak as soon as practicable, but no later than 30 days
after receiving the sampling results that indicate the presence of a
leak.
    (d) Except for a delay allowed under paragraph (e) of this section,
the owner or operator must repair any leak as soon as practicable, but
no later 30 days after identifying the source of leak. Repairs may
include:
    (1) Physical repairs to the leaking heat exchanger;
    (2) Blocking the leaking tube within the heat exchanger;
    (3) Changing the pressure so that water flows into the process
fluid; or
    (4) Replacing the heat exchanger.
    (e) The owner or operator may delay the repair of a leak if the
conditions in paragraph (e)(1) or paragraph (e)(2) of this section are
met.
    (1) Repairing the leak would require the process unit served by the
leaking heat exchanger to be shut down, and a shutdown for repair would
cause greater emissions than the potential emissions from the cooling
tower from the time the leaking exchanger was first identified and the
next planned shutdown.
    (i) The facility must use the startup and shutdown emissions
estimates in the cooling tower monitoring plan required by paragraph
(f) of this section for the estimate of total organic HAP emissions for
the process unit serviced by the leaking heat exchanger.
    (ii) The owner or operator must conduct monthly monitoring of the
total organic HAP concentration using EPA Method 8260B (incorporated by
reference--see Sec.  63.14).
    (iii) The owner or operator shall recalculate the potential air
emissions from the cooling tower using the new sampling results and the
time period between the most recent sampling results and the next
planned shutdown. If the potential air emissions from the cooling tower
exceed the startup and shutdown emission estimates for any month, the
owner or operator must repair the heat exchanger within 30 days of
receiving the sampling results that voided the delay of repair; or
    (2) The necessary parts are not reasonably available, in which case
the owner or operator must complete the repair as soon as practicable
upon receiving the necessary parts, but no later than 120 days after
identifying the leaking exchanger. The owner or operator can not
further delay the repair when a sampling result voids the delay of
repair under paragraph (e)(1)(iii) of this section.
    (f) The owner or operator shall prepare, implement, and maintain
onsite at all times a cooling tower monitoring plan that includes the
information specified in paragraphs (f)(1) through (11) of this
section.
    (1) Identification of all cooling tower systems at the facility;

    (2) Identification of the cooling tower systems subject to this
subpart;
    (3) Identification of the cooling tower systems receiving cooling
water from a heat exchanger that are exempt from this subpart according
to Sec.  63.640(s);

serviced by each cooling tower system that is subject to this subpart;
    (5) The HAP concentration of the process fluids in each heat
exchanger serviced by a cooling tower system subject to this subpart;
    (6) The surrogate parameters to be monitored, the monitoring
frequency, and parameter operating limits for each cooling tower system
subject to this subpart;
    (7) The methods used to identify the leaking heat exchanger once a
leak is detected;
    (8) Standard repair procedures that reduce emissions from leaks;
    (9) Procedures for reporting leaks into the cooling water system;
    (10) List of critical spare parts that must be maintained in
inventory;
    (11) Engineering estimates of startup and shutdown organic HAP
emissions for each process unit serviced by a cooling tower subject to
this subpart.

Option 2 for Sec.  63.654

    13. Section 63.654 is added to read as follows:

Sec.  63.654  Cooling tower systems.

    (a) On and after the compliance date specified in Sec.
63.650(h)(8), the owner or operator of a new or existing source shall
monitor the concentration of HAP from each cooling tower system subject
to this subpart on a monthly basis to identify and repair any leak with
a potential mass leak rate of 10 pounds per day (lb/day) or greater of
any single HAP listed in Table 1 of this subpart or 100 lb/day or
greater of total HAP listed in Table 1 of this subpart. A heat exchange
system may consist of an entire heat exchange system or a combination
of heat exchangers such that, based on the rate of cooling water and
the sensitivity of the test method, a leak of 10 lb/day or greater of
any single HAP listed in Table 1 of this subpart or 100 lb/day or
greater of total HAP would be detected. The owner or operator shall
conduct the monthly monitoring according to the methods and procedures
in paragraphs (a)(1) through (3) of this section.
    (1) Collect a water sample from each cooler water return line(s)
prior to air stripping or exposure to air. You must collect each sample
using the sampling procedures in Sec.  61.355(c)(3) of the National
Emission Standard for Benzene Waste Operations.
    (2) Analyze each sample using EPA Method 8260B (incorporated by
reference--see Sec.  63.14). Determine the total organic HAP
concentration as the sum of the individual HAP concentrations of the
HAP listed in Table 1 of this subpart.
    (3) Calculate and record the potential mass leak rate using
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TP04SE07.005

Where:

L = Potential mass leak rate of HAP (lb/day);
0.012 = Constant for unit conversion (lb/gallon x minutes/day x part
per million parts);
CHAP = Concentration of individual or total organic HAP
in the cooling tower water prior to exposure to the air (ppmw); and
QCT = Volumetric flow rate of cooling water to the
cooling tower (gallons per minute).

    (b) If the results of Equation 1 of this section indicate a leak
with a mass leak rate of 10 lb/day of any single HAP or 100 lb/day of
total HAP per day or greater, the owner or operator must identify the
source of the leak as soon as practicable, but no later than 30 days
after receiving the sampling results that indicate the presence of a
leak.
    (c) Except for a delay allowed under paragraph (d) of this section,
the owner or operator must repair any leak with a mass leak rate of 10
pounds of any single Table 1 HAP or 100 pounds of total Table 1 HAP per
day or greater as soon as practicable, but no later than 30 days after
identifying the source of leak. Repairs may include:
    (1) Physical repairs to the leaking heat exchanger;
    (2) Blocking the leaking tube within the heat exchanger;
    (3) Changing the pressure so that water flows into the process
fluid; or
    (4) Replacing the heat exchanger.
    (d) The owner or operator may delay the repair of a leak if the
conditions in paragraph (d)(1) or paragraph (d)(2) of this section are
met.
    (1) Repairing the leak would require the process unit served by the
leaking heat exchanger to be shut down, and a shutdown for repair would
cause greater emissions than the potential emissions from the cooling
tower from the time the leaking exchanger was first identified and the
next planned shutdown.
    (i) The facility must use the startup and shutdown emissions
estimates in the cooling tower monitoring plan required by paragraph
(e) of this section for the estimate of HAP emissions for the process
unit serviced by the leaking heat exchanger.
    (ii) The owner or operator must continue monthly monitoring of HAP
as required by paragraph (a) of this section.
    (iii) The owner or operator shall recalculate the potential air
emissions from the cooling tower using the new sampling results and the
time period between the most recent sampling results and the next
planned shutdown. If the potential air emissions from the cooling tower
exceed the startup and shutdown emission estimates for any month, the
owner or operator must repair the heat exchanger within 30 days of
receiving the sampling results that voided the delay of repair; or
    (2) The necessary parts are not reasonably available, in which case
the owner or operator must complete the repair as soon as practicable
upon receiving the necessary parts, but no later than 120 days after
identifying the leaking exchanger. The owner or operator cannot further
delay the repair when a sampling result voids the delay of repair under
paragraph (d)(1)(iii) of this section.
    (e) The owner or operator shall prepare, implement, and maintain
onsite at all times a cooling tower monitoring plan that includes the
information specified in paragraphs (e)(1) through (10) of this
section.
    (1) Identification of all cooling tower systems at the facility;
    (2) Identification of the cooling tower systems subject to this
subpart;
    (3) Identification of the cooling tower systems receiving cooling
water from a heat exchanger that are exempt from this subpart according
to Sec.  63.640(s);
    (4) Identification of the heat exchanger(s) and process unit(s)
serviced by each cooling tower system that is subject to this subpart;
    (5) The HAP concentration of the process fluids in each heat
exchanger serviced by a cooling tower system subject to this subpart;
    (6) The methods used to identify the leaking heat exchanger once a
leak is detected;
    (7) Standard repair procedures that reduce emissions from leaks;
    (8) Procedures for reporting leaks into the cooling water system;
    (9) List of critical spare parts that must be maintained in
inventory;
    (10) Engineering estimates of startup and shutdown HAP emissions
for each process unit serviced by a cooling tower subject to this
subpart.
