[NPDES No. FLG830000; FRL-5073-3]

Reissuance of the National Pollutant Discharge Elimination System

(NPDES) General Permit for Petroleum Fuel Contaminated Ground/Storm

Waters in the State of Florida

AGENCY: Environmental Protection Agency.

ACTION: Notice of Reissuance of a NPDES General Permit to the State of

Florida.

-----------------------------------------------------------------------

SUMMARY: The Regional Administrator, EPA, Region IV intends to reissue

the National Pollutant Discharge Elimination System (NPDES) General

Permit No. FLG830000 to facilities within the political boundary of the

State of Florida. This proposed reissued NPDES general permit proposes

effluent limitations, prohibitions, reporting requirements and other

conditions on facilities which discharge uncontaminated groundwater

associated with dewatering or treated groundwater and/or storm water

incidental to the groundwater cleanup operation which have been

contaminated by automotive gasoline, aviation and/or diesel fuels. This

permit authorizes discharges from facilities currently located in and

discharging to surface waters within the political boundary of the

State of Florida, and any new treatment facilities placed in operation

during the term of this permit.

Except for facilities meeting the conditions of Part I.3, written

notice of intent to be covered by the reissued NPDES general permit

shall be provided to the Permit Issuing Authority prior to initiation

of any discharge to waters of the United States. For facilities that

must submit a Notice of Intent (NOI), coverage by this NPDES general

permit is authorized upon receipt of written notification of coverage

from the Permit Issuing Authority. The proposed reissued permit

contains limitations on the amounts of pollutants allowed to be

discharged and was drafted in accordance with the provisions of the

Clean Water Act (33 U.S.C. 1251 et seq.) and other lawful standards and

regulations. The pollutant limitations and other permit conditions are

tentative and open to comment from the public.

ADDRESSES: Persons wishing to comment upon or object to any aspects of

a specific permit reissuance or wishing to request a public hearing,

are invited to submit same in writing within thirty (30) days of this

notice to the Office of Public Affairs, Environmental Protection

Agency, 345 Courtland Street, NE., Atlanta, Georgia 30365, Attention:

Ms. Lena Scott, Public Notice Coordinator. Pursuant to 40 CFR 124.13,

any person who believes that any permit condition is inappropriate must

raise all reasonably ascertainable issues and position, by the close of

the comment period. The public notice number and NPDES number should be

included in the first page of comments. All comments received within

the 30-day period will be considered in the formulation of a final

determination regarding the reissuance of this NPDES general permit.

Also, within the 30-day period any interested person may request a

public hearing. Where there is a significant degree of public interest

in the proposed general permit reissuance, the EPA Regional

Administrator will schedule and hold a public hearing which would be

formally announced in accordance with 40 CFR 124.10 and 124.12.

After consideration of all written comments and the requirements

and policies in the Act and appropriate regulations, the EPA Regional

Administrator will make a determination regarding the reissuance of

this NPDES general permit. If the determination is substantially

unchanged from that announced by this notice, the EPA Regional

Administrator will so notify all persons submitting written comments.

If the determination is substantially changed, the EPA Regional

Administrator will issue a public notice indicating the revised

determination. A formal hearing is available to challenge any NPDES

permit issued under 40 CFR 124.14 except for a general permit. Persons

affected by a general permit may not challenge the conditions of a

general permit as a right in further agency proceedings.

They may instead either challenge the general permit in court, or

apply for an individual permit under 40 CFR 122.21 as authorized at 40

CFR 122.28 and then request a formal hearing on the issuance or denial

of an individual permit. The administrative record, including draft

NPDES general permit, fact sheet, state certification, comments

received, and additional information are available by writing the EPA,

*Monitoring for this parameter is required only when contamination results from leaded fuel.

An LC50 of 100% or less in a test of 96 hours duration or less

will constitute a violation of Florida Administrative Code (FAC) (July

11, 1993) Sec. 17-4.244(3)(a) and the terms of this permit. The testing

for this requirement must conform with Part V of this permit.

For fresh waters and coastal waters, the pH of the effluent shall

not be lowered to less than 6.0 units for fresh waters, or less than

6.5 units for marine waters, or raised above 8.5 units, unless the

permittee submits natural background data in the NOI request confirming

a natural background pH outside of this range. If natural background of

the receiving water, as revealed by sampling data from the permittee in

the NOI request, is determined to be less than 6.0 units for fresh

waters, or less than 6.5 units in marine waters, the pH shall not vary

below natural background or vary more than one (1) unit above natural

background for fresh and coastal waters. If natural background of the

receiving water, as revealed by sampling data from the permittee in the

NOI request, is determined to be higher than 8.5 units, the pH shall

not vary above natural background or vary more than one (1) unit below

natural background of fresh and coastal waters. The acceptable pH range

will be included in the letter granting permit coverage and on the DMR.

The pH shall be monitored once every month by grab sample, or

continuously with a recorder. (See item I.B.4).

In accordance with FAC Sec. 17-302.500(1)(a-c)(4-25-93), the

discharge shall at all times be free from floating solids, visible

foam, turbidity, or visible oil in such amounts as to form nuisances on

surface waters.

Samples taken in compliance with the monitoring requirements

specified above shall be taken at the following location(s): Nearest

accessible point after final treatment but prior to actual discharge or

mixing with the receiving waters.

A. Effluent Limitations and Monitoring Requirements

3. During the period beginning on the effective date of the permit

and lasting through the term of this permit, the permittee is

authorized to discharge produced groundwater from any noncontaminated

site activity which discharges by a point source to waters of the

United States, only if the reported values for the parameters listed

below do not exceed any of the screening values below. Before discharge

of produced groundwater can occur from such sites, analytical tests on

samples of the proposed discharge water shall be performed to determine

if contamination exists from other sources.

Minimum reporting requirements for all produced groundwater

dischargers.

The effluent shall be sampled at the final effluent before the

commencement of discharge and once every six months for the life of the

project to maintain continued coverage under this general permit. The

effluent shall be sampled for the parameters listed below and the

analytical results obtained shall be submitted to EPA at the address

given in Part III.A.

------------------------------------------------------------------------

If any of the analytical test results exceed the above screening

values, discharge is not authorized by this permit. See paragraph

I.A.3.b for further guidance.

In accordance with FAC 17-302.500(1)(a-c), the discharge shall at

all times be free from floating solids, visible foam, turbidity, or

visible oil in such amounts as to form nuisances on surface waters.

All discharges must comply with the following permit requirements:

(a) If analytical tests of Part I.A.3 reveal excessive benzene and

naphthalene concentrations indicative of contamination from petroleum

fuels, and the discharge will occur for thirty (30) days or less, the

permittee shall comply only with the applicable effluent limitations

and monitoring requirements in Part I.A.1 or I.A.2 for benzene, pH,

and/or naphthalene and total lead. The commencement of the Part V

biomonitoring program and Part I.B.3 EPA method 624 and 625 (one time

analysis) is not required for this short-term activity. One (1) grab

sample shall be analyzed per seven (7) days during the discharge

period, and the total volume discharged shall be recorded. For

discharges contaminated by petroleum fuels that last for less than a

week, daily monitoring will be required for the applicable parameters.

Upon receipt of written EPA notification of coverage that the NOI

request is complete, these short-term discharges may commence.

Discharge Monitoring Reports shall be submitted to EPA within thirty

(30) days after termination of the discharge.

(b) If contamination from sources other than petroleum

contamination does exist, as indicated by the results of the analytical

tests required by Part I. A.3 above, the discharge is not covered by

this general permit. The operator shall apply for an individual NPDES

permit at least ninety (120) days prior to the date a discharge to

waters of the United States is expected. No discharge is permissible

without an effective NPDES permit.

(c) If analytical tests reveal no contamination exists from

petroleum fuels or sources other than petroleum contamination as a

result of the required analytical screening tests required in Part I,

A.3, the permittee can commence discharge immediately and is covered by

this permit without having to submit an NOI request for coverage to

EPA, Region IV. A short summary of the proposed activity and copy of

these analytical tests shall be sent to the same address specified in

Part III.A at least (1) one week before discharge begins. These

analytical tests shall be kept on site during discharge and made

available to EPA, if requested. Additionally, no Discharge Monitoring

Report (DMR) forms are required to be submitted to EPA, Region IV.

B. Other Requirements

1. Any more frequent effluent discharge monitoring required by the

Florida Department of Environmental Protection (FDEP) for the

parameters limited in this permit, or different parameters, shall be

reported to the Permit Issuing Authority in accordance with the

requirements of Part III of this permit.

2. Effluent limitations for combining contaminated groundwater

pumped to above-ground storage tanks with contaminated groundwater from

the site's recovery wells: The permittee shall notify FDEP of any

intent to combine contaminated groundwater pumped to above-ground

storage tanks with contaminated groundwater from the recovery well.

Approval of this combined effluent discharge by FDEP will constitute

approval to apply for coverage under this permit.

3. Within sixty (60) days of the effective date of this permit or

startup of discharge the permittee shall also submit the results of the

following analyses. These analyses shall be performed on a

representative sample of the groundwater effluent discharge, taken

after final treatment.

Required analyses (one time only):

a. EPA Method 625--Acid and base/neutral extractable organics

b. EPA Method 624--Purgeable Organics

If such analyses required in Part B.3 above reveal toxic pollutants

other than those regulated in Part I.A. or subsequent Whole Effluent

Toxicity (WET) tests reveal an LC50 of 100% or less in a test of

96 hours duration or less, coverage under this general permit will be

reviewed for termination by EPA Region IV Enforcement Section.

4. If the pH is monitored continuously, the pH values shall not

deviate outside the required range more than 1% of the time in any

calendar month; and no individual excursion shall exceed 60 minutes. An

``excursion'' is an unintentional and temporary incident in which the

pH value of discharge wastewater exceeds the range set forth in this

permit.

C. Test Procedures

1. In performing the analysis for the dissolved constituents in the

surface water and groundwater, the permittee shall use the guidelines

recommended and described in FAC Sections 17-770.600(8)[a-d] of the

Petroleum Contamination Cleanup Criteria (PCCC), amended February 20,

1990, or the most current edition.

2. If the petroleum contamination is from a petroleum fuel in which

the source of contamination has not been identified, the groundwater

shall be analyzed (using the recommended methods) for the following

parameters as described in FAC Section 17.770.600(8)(c)1, of the PCCC,

amended February 20, 1990, or the most current edition:

a. Lead............................ (EPA Method 239.2 or Standard

Method 304).

b. Priority Pollutant Volatile (EPA Method 624).

Organics.

c. Priority Pollutant Extractable (EPA Method 625).

Organics.

d. Non-Priority Pollutant Organics (EPA Methods 624 and 625).

(with GC/MS Peaks greater than 10

ppb).

D. Schedule of Compliance

1. The permittee shall achieve compliance with the effluent

limitations specified for discharges in accordance with the following

schedule:

Permittees with Revoked Individual Permits:

Operational level attained--Upon Receipt of Notification of

Coverage

New Dischargers:

Operational level attained--Upon Commencement of Discharge

2. No later than fourteen (14) calendar days after any date

identified in the above schedule of compliance the permittee shall

submit either a report of progress or, in the case of specific actions

being required by identified dates, a written notice of compliance or

noncompliance. In the latter case, the notice shall include the cause

of noncompliance, any remedial actions taken, and the probability of

meeting the next scheduled requirement.

Part II

Standard Conditions for NPDES Permits

Section A. General Conditions

1. Duty To Comply

The permittee must comply with all conditions of this permit. Any

permit noncompliance constitutes a violation of the Clean Water Act and

is grounds for enforcement action; for permit termination, revocation

and reissuance, or modification; or for denial of a permit renewal

application.

2. Penalties for Violations of Permit Conditions

Any person who violates a permit condition is subject to a civil

penalty not to exceed $25,000 per day of such violation. Any person who

willfully or negligently violates permit conditions is subject to a

fine of up to $50,000 per day of violation, or by imprisonment for not

more than 1 year, or both. Any person who knowingly violates permit

conditions is subject to criminal penalties of $5,000 to 50,000 per day

of violation, or imprisonment for not more than 3 years, or both. Also,

any person who violates a permit condition may be assessed an

administrative penalty not to exceed $10,000 per violation with the

maximum not to exceed $125,000. [Ref: CFR 122.41(a)].

3. Duty To Mitigate

The permittee shall take all reasonable steps to minimize or

prevent any discharge in violation of this permit which has a

reasonable likelihood of adversely affecting human health or the

environment.

4. Duty To Reapply

Where EPA is the Permit Issuing Authority (PIA), the terms and

conditions of this permit are automatically continued in accordance

with 40 CFR 122.6, only where the permittee has submitted a timely and

complete Notice of Intent 180 days prior to expiration of this permit,

and the PIA is unable through no fault of the permittee to issue a new

permit before the expiration date.

5. Permit Modification

After notice and opportunity for a hearing, this permit may be

modified, terminated, or revoked for cause (as described in 40 CFR

122.62 et seq.) including, but not limited to, the following:

a. Violation of any terms or conditions of this permit;

b. Obtaining this permit by misrepresentation or failure to

disclose fully all relevant facts;

c. A change in any conditions that requires either temporary

interruption or elimination of the permitted discharge; or

d. Information newly acquired by the Agency indicating the

discharge poses a threat to human health or welfare.

If the permittee believes that any past or planned activity would

be cause for modification or revocation and reissuance under 40 CFR

122.62, the permittee must report such information to the Permit

Issuing Authority. The submittal of a new application may be required

of the permittee. The filing of a request by the permittee for a permit

modification, revocation and reissuance, or termination, or a

notification of planned changes or anticipated noncompliance, does not

stay any permit condition.

6. Toxic Pollutants

Notwithstanding Paragraph A-4, above, if a toxic effluent standard

or prohibition (including any schedule of compliance specified in such

effluent standard or prohibition) is established under Section 307(a)

of the Act for a toxic pollutant which is present in the discharge and

such standard or prohibition is more stringent than any limitation for

such pollutant in this permit, this permit shall be modified or revoked

and reissued to conform to the toxic effluent standard or prohibition

and the permittee so notified.

7. Civil and Criminal Liability

Except as provided in permit conditions on ``Bypassing'' Section B,

Paragraph B-3, nothing in this permit shall be construed to relieve the

permittee from civil or criminal penalties for noncompliance.

8. Oil and Hazardous Substance Liability

Nothing in this permit shall be construed to preclude the

institution of any legal action or relieve the permittee from any

responsibilities, liabilities, or penalties to which the permittee is

or may be subject under Section 311 of the Act.

9. State Laws

Nothing in this permit shall be construed to preclude the

institution of any legal action or relieve the permittee from any

responsibilities, liabilities, or penalties established pursuant to any

applicable State law or regulation under authority preserved by Section

510 of the Act.

10. Property Rights

The issuance of this permit does not convey any property rights of

any sort, or any exclusive privileges, nor does it authorize any injury

to private property or any invasion of personal rights, nor any

infringement of Federal, State or local laws or regulations.

11. Severability

The provisions of this permit are severable, and if any provision

of this permit, or the application of any provision of this permit to

any circumstance, is held invalid, the application of such provision to

other circumstances, and the remainder of this permit, shall not be

affected thereby.

12. Duty to Provide Information

The permittee shall furnish to the Permit Issuing Authority, within

a reasonable time, any information which the Permit Issuing Authority

may request to determine whether cause exists for modifying, revoking

and reissuing, or terminating this permit or to determine compliance

with this permit. The permittee shall also furnish to the Permit

Issuing Authority upon request, copies of records required to be kept

by this permit.

Section B. Operation and Maintenance of Pollution Controls

1. Proper Operation and Maintenance

The permittee shall at all times properly operate and maintain all

facilities and systems of treatment and control (and related

appurtenances) which are installed or used by the permittee to achieve

compliance with the conditions of this permit. Proper operation and

maintenance also includes adequate laboratory controls and appropriate

quality assurance procedures. This provision requires the operation of

back-up or auxiliary facilities or similar systems which are installed

by a permittee only when the operation is necessary to achieve

compliance with the conditions of the permit.

2. Need to Halt or Reduce not a Defense

It shall not be a defense for a permittee in an enforcement action

that it would have been necessary to halt or reduce the permitted

activity in order to maintain compliance with the condition of this

permit.

3. Bypass of Treatment Facilities

a. Definitions

(1) Bypass means the intentional diversion of waste streams from

any portion of a treatment facility, which is not a designed or

established operating mode for the facility.

(2) Severe property damage means substantial physical damage to

property, damage to the treatment facilities which causes them to

become inoperable, or substantial and permanent loss of natural

resources which can reasonably be expected to occur in the absence of a

bypass. Severe property damage does not mean economic loss caused by

delays in production.

b. Bypass not exceeding limitations.

The permittee may allow any bypass to occur which does not cause

effluent limitations to be exceeded, but only if it also is for

essential maintenance to assure efficient operation. These bypasses are

not subject to the provisions of Paragraphs c. and d. of this section.

c. Notice

(1) Anticipated bypass. If the permittee knows in advance of the

need for a bypass, it shall submit prior notice, if possible at least

ten days before the date of the bypass; including an evaluation of the

anticipated quality and effect of the bypass.

(2) Unanticipated bypass. The permittee shall submit notice of an

unanticipated bypass as required in Section D, Paragraph D-4 (24-hour

notice).

d. Prohibition of bypass.

(1) Bypass is prohibited and the Permit Issuing Authority may take

enforcement action against a permittee for bypass, unless:

(a) Bypass was unavoidable to prevent loss of life, personal

injury, or severe and extensive property damage;

(b) There were no feasible alternatives to the bypass, such as

maintenance of sufficient reserve holding capacity, the use of

auxiliary treatment facilities, retention of untreated wastes, waste

hauling, or maintenance during normal periods of equipment downtime.

This condition is not satisfied if adequate back-up equipment should

have been installed in the exercise of reasonable engineering judgment

to prevent a bypass which occurred during normal periods of equipment

downtime or preventive maintenance; and

(c) The permittee submitted notices as required under Paragraph c.

of this section.

(2) The Permit Issuing Authority may, within its authority, approve

an anticipated bypass, after considering its adverse effects, if the

Permit Issuing Authority determines that it will meet the three

conditions listed above in Paragraph d.(1) of this section.

4. Upsets

``Upset'' means an exceptional incident in which there is

unintentional and temporary noncompliance with technology based permit

effluent limitations because of factors beyond the control of the

permittee. An upset does not include noncompliance to the extent caused

by operational error, improperly designed treatment facilities,

inadequate treatment facilities, lack of preventive maintenance, or

careless or improper operation. An upset constitutes an affirmative

defense to an action brought for noncompliance with such technology

based permit limitation if the requirements of 40 CFR 122.41(n)(3) are

met. (Note that this provision does not apply to water quality

requirements.)

5. Removed Substances

This permit does not authorize discharge of solids, sludge, filter

backwash, or other pollutants removed in the course of treatment or

control of wastewaters to waters of the United States unless

specifically limited in Part 1.

Section C. Monitoring and Records

1. Representative Sampling

Samples and measurements taken as required herein shall be

representative of the volume and nature of the monitored discharge. All

samples shall be taken at the monitoring points specified in this

permit and, unless otherwise specified, before the effluent joins or is

diluted by any other wastestream, body of water, or substance.

Monitoring points shall not be changed without notification to and the

approval of the Permit Issuing Authority.

2. Flow Measurements

Appropriate flow measurement devices and methods consistent with

accepted scientific practices shall be selected and used to insure the

accuracy and reliability of measurements of the volume of monitored

discharges. The devices shall be installed, calibrated and maintained

to insure that the accuracy of the measurements are consistent with the

accepted capability of that type of device. Devices selected shall be

capable of measuring flows with a maximum deviation of less than

10% from the true discharge rates throughout the range of

expected discharge volumes. Guidance in selection, installation,

calibration and operation of acceptable flow measurement devices can be

obtained from the following references:

Section E. Definitions

1. Permit Issuing Authority

The Regional Administrator of EPA Region IV or his designee, unless

at some time in the future the State receives the authority to

administer the NPDES program and assumes jurisdiction over the permit;

at which time, the Director of the State program receiving

authorization becomes the issuing authority.

2. Act

Act means the Clean Water Act (formerly referred to as the Federal

Water Pollution Control Act) Public Law 92-500, as amended by Public

Laws 95-217, 95-576, 96-483,97-117, and Public Law 100-4, 33 U.S.C.

1251 et seq.

3. Concentration Measurements

a. The ``average monthly concentration'', is the sum of the

concentrations of all daily discharges sampled and/or measured during a

calendar month on which daily discharges are sampled and measured,

divided by the number of daily discharges sampled and/or measured

during such month (arithmetic mean of the daily concentration values).

The daily concentration value is equal to the concentration of a

composite sample or in the case of grab samples is the arithmetic mean

(weighted by flow value) of all the samples collected during the

calendar day.

b. The ``maximum daily concentration'', is the concentration of a

pollutant discharge during a calendar day. It is identified as ``Daily

Maximum'' under ``Other Limits'' in Part I of the permit and the

highest such value recorded during the reporting period is reported

under the ``Maximum'' column under ``Quality'' on the DMR.

4. Other Measurements

a. The effluent flow expressed as MGD is the 24 hour average flow

averaged monthly. It is the arithmetic mean of the total daily flows

recorded during the calendar month. Where monitoring requirements for

flow are specified in Part I of the permit the flow rate values are

reported in the ``Average'' column under ``Quantity'' on the DMR.

b. An ``instantaneous flow measurement'' is a measure of flow taken

at the time of sampling, when both the sample and flow will be

representative of the total discharge.

c. Where monitoring requirements for pH or dissolved oxygen are

specified in Part I of the permit, the values are generally reported in

the ``Quality or Concentration'' column on the DMR.

5. Types of Samples

a. Grab Sample: A ``grab sample'' is a single influent or effluent

portion which is not a composite sample. The sample(s) shall be

collected at the period(s) most representative of the total discharge.

6. Calendar Day

A calendar day is defined as the period from midnight of one day

until midnight of the next day. However, for purposes of this permit,

any consecutive 24-hour period that reasonably represents the calendar

day may be used for sampling.

7. Hazardous Substance

A hazardous substance means any substance designated under 40 CFR

Part 116 pursuant to Section 311 of the Clean Water Act.

8. Toxic Pollutant

A toxic pollutant is any pollutant listed as toxic under Section

307(a)(1) of the Clean Water Act.

Section F. Application Requirements

discharge location (including latitude and longitude), and (7) the name

of the receiving water. Operators having several individual permits are

encouraged to consolidate requests for coverage into one NOI for all

individual permits. The previous submission of the proper forms in the

renewal application does not relieve the permittee desiring coverage

under the general permit of the requirement to file a NOI.

b. Dischargers with current individual NPDES permits that desire

coverage under this general permit are required to file an NOI to the

Permit Issuing Authority at least thirty (30) days prior to expiration

of their current permit(s). The NOI shall contain the same information

individual permit are required to submit the appropriate application

forms at least 180 days before expiration of their individual permit.

c. Dischargers who have not previously obtained an individual NPDES

permit are required to submit to EPA the FDEP approval order letter

approving the site RAP. The RAP approval order shall be attached to an

NOI to be covered by the general permit and shall contain the same

information specified in paragraph a above. The application for

coverage under the general permit must be made at least forty-five (45)

days before the discharge is to commence.

d. Dischargers seeking coverage under Part I A.3.a. will be

required to submit to EPA the date the discharge is expected to cease,

results of analytical data and the same information in paragraph a

above, except items (3), (4) and (5). Notification of coverage to

discharge will be upon receipt of EPA's short-term coverage letter.

e. Notification of coverage will be given by the Permit Issuing

Authority by certified mail to the permittee, for dischargers seeking

coverage under Part I Sections A.1 and A.2, with the issuance date for

each facility being the effective date of coverage by the Permit

Issuing Authority.

f. Dischargers meeting the conditions set forth in Part I A.3.c.

are not required to submit an detailed NOI as outlined above, but must

submit a copy of the analytical tests and a summary of the proposed

activity at least one (1) week before discharge begins. These

dischargers are covered upon receipt of the data, unless notified

otherwise by EPA.

g. The coverage of the permit shall expire on ____________, five

(5) years from the effective date of the permit.

h. In accordance with 40 CFR 122.28(a)(2) permittees who are

covered by this general permit who seek to be continued under this

general permit, shall submit an complete NOI in accordance with

paragraph a, to EPA 180 days before the expiration of this permit.

Section G. Additional General Permit Conditions

1. The Permit Issuing Authority may require any person authorized

by this permit to apply for and obtain an individual NPDES permit when:

a. The discharge(s) is a significant contributor of pollution;

(5) In the opinion of the RA, are more appropriately controlled

under an individual permit than under a general permit.

The Regional Administrator (RA) may require any operator authorized

by this permit to apply for an individual NPDES permit only if the

operator has been notified in writing that a permit application is

required.

2. Any operator authorized to discharge by this permit may request

to be excluded from the coverage of this general permit by applying for

an individual permit. The operator shall submit an application together

with the reasons supporting the request to the RA.

3. When an individual NPDES permit is issued to an operator

otherwise subject to this general permit, the applicability of this

permit to the owner or operator is automatically terminated on the

effective date of the individual permit.

4. A source excluded from coverage under this general permit solely

because it already has an individual permit may request that its

individual permit be revoked, and that it be covered by this general

permit. Upon revocation of the individual permit, this general permit

shall apply to the source.

5. A petroleum contamination recovery operation may be excluded

from this general permit if it proposes discharges to receiving waters

standard or limitation so issued or approved--

1. Contains different conditions or is otherwise more stringent

than any condition in this permit; or

2. Controls any pollutant not limited in the permit. The permit as

modified or reissued under this paragraph shall also contain any other

requirements of the Act then applicable.

Part IV

Best Management Practices and Pollution Prevention Conditions

Section A. General Conditions

1. BMP Plan

Preparation of a Best Management Practices (BMP) Plan shall be

prepared in conjunction with development of the Remedial Action Plan

required by Florida Department of Environmental Protection (See Part

II.F.c.). The permittee shall maintain the BMP plan at the facility and

shall make the plan available to the permit issuing authority upon

request. The ``NPDES Guidance Document'' can be used as a reference

which contains technical information on BMPs and the elements of the

BMP program. The permittee shall develop and implement a BMP plan which

prevents, or minimizes the potential for, the release of pollutants

from ancillary activities, including material storage areas; plant site

runoff; in-plant transfer, process and material handling areas; loading

and unloading operations, and sludge and waste disposal areas, to the

waters of the United States through plant site runoff; spillage or

leaks; sludge or waste disposal; or drainage from raw material storage.

The term pollutants refers to any substance listed as toxic under

Section 307(a)(1) of the Clean Water Act, oil, as defined in Section

311(a)(1) of the Act, and substance listed as hazardous under Section

311 of the Act. Copies of the ``NPDES Guidance Document'' may be

obtained by submitting written requests to: Director, Water Management

Division, U.S. EPA Region IV, 345 Courtland St. N.E., Atlanta, Georgia

30365.

discharge one (1) year or more shall develop a Pollution Prevention

Plan for the site and submit it with the NOI. It shall contain the

following information:

(a) A Narrative of What Caused the Groundwater Contamination.

(b) Methods currently being deployed at the site to prevent

groundwater contamination from reoccurring.

(c) Other alternative treatment options which were considered in

reducing the groundwater contamination.

(d) Explanation of why long term treatment of discharge to Surface

Waters of the United States was chosen as opposed to:

(1) Reduction-Monitor Phase I--Using a combination of techniques to

significantly reduce groundwater contamination that could be achieved

in three (3) months or less, with the objective of reaching a monitor-

only status.

(2) Reduction-Monitor Phase II--Using a combination of techniques

to significantly reduce groundwater contamination that could be

achieved in six (6) months or less, with the objective of reaching a

monitor-only status.

In an effort to promote pollution prevention, the Permit Issuing

Authority may issue permits which include or require pollution

prevention activities.

Part V

Whole Effluent Toxicity Testing Program Acute Freshwater Language

As required by Part I of the permit, within 30-days after

commencement of discharge, permittees discharging to fresh waters,

which are surface waters in which the chloride concentration at the

surface is less than 1500 milligrams per liter, shall initiate the

series of tests described below to evaluate whole effluent toxicity of

the discharge from the outfall. If more than one (1) outfall exists,

separate tests will be performed on each outfall. All test species,

procedures and quality assurance criteria used shall be in accordance

with Methods for Measuring the Acute Toxicity of Effluents to

Freshwater and Marine Organisms, EPA/600/4-90/027F, or the most current

edition. The dilution/control water used will be moderately hard water

as described in EPA/600/4-90/027F, Section 7, or the most current

edition. A standard reference toxicant quality assurance test shall be

conducted concurrently with each species used in the toxicity tests and

the results submitted with the discharge monitoring report (DMR).

Alternatively, if monthly QA/QC reference toxicant tests are conducted,

these results must be submitted with the DMR.

1. a. The permittee shall conduct 96-hour acute static-renewal

multi-concentration toxicity tests using the daphnid (Ceriodaphnia

dubia) and the fathead minnow (Pimephales promelas). All tests shall be

conducted on one grab sample of 100% final effluent. All tests shall be

conducted on a control (0%) and the following dilution concentrations

at a minimum: 100.0%, 50.0%, 25.0%, 12.5%, and 6.25%.

b. If control mortality exceeds 10% for either species in any test,

the test(s) for that species (including the control) shall be repeated.

A test will be considered valid only if control mortality does not

exceed 10% for either species.

2. The toxicity tests specified above shall be conducted once every

month until three (3) valid monthly tests have been completed, and once

every year thereafter for the duration of the permit, unless notified

otherwise by the permit issuing authority. These tests are referred to

as ``routine'' tests.

3. a. If unacceptable acute toxicity (an LC50 of 100% or less

occurs in either test species in any of the above-described tests

within the specified time) is found in a ``routine'' test, the

permittee shall conduct two additional acute toxicity tests in the same

manner as the ``routine'' test on the specie(s) indicating unacceptable

acute toxicity. For each additional test, the sample collection

requirements and test acceptability criteria specified in Section 1

above must be met for the test to be considered valid. The first test

shall begin within two weeks of the end of the ``routine'' tests, and

shall be conducted weekly thereafter until two additional, valid tests

are completed. The additional tests will be used to determine if the

toxicity found in the ``routine'' test is still present.

b. Results from additional tests, required due to unacceptable

acute toxicity in the ``routine'' test(s), must be reported on the

Discharge Monitoring Report (DMR) Form for the month in which the test

was begun. Such test results must be submitted within 45 days of

completion of the second additional, valid test.

As required by Part I of this permit, within 30-days after

commencement of discharge, permittees discharging to marine waters,

which are surface waters in which the chloride concentration at the

surface is greater than or equal to 1500 milligrams per liter, shall

initiate the series of tests described below to evaluate whole effluent

toxicity of the discharge from the outfall. If more than one (1)

outfall exists, separate tests will be performed on each outfall. All

test species, procedures and quality assurance criteria used shall be

in accordance with Methods for Measuring the Acute Toxicity of

Effluents to Freshwater and Marine Organisms, EPA/600/4-90/027F, or the

most current edition. The dilution/control water and effluent used will

be adjusted to a salinity of 20 parts per thousand using artificial sea

salts as described in EPA/600/4-90/027F, Section 7 (or the most current

edition). A standard reference toxicant quality assurance test shall be

conducted concurrently with each species used in the toxicity tests and

the results submitted with the discharge monitoring report (DMR).

Alternatively, if monthly QA/QC reference toxicant tests are conducted,

these results must be submitted with the DMR.

1. a. The permittee shall conduct 96-hour acute static-renewal

multi-concentration toxicity tests using the mysid shrimp (Mysidopsis

bahia) and the inland silverside (Menidia beryllina). All tests shall

be conducted on one grab sample of 100% final effluent. All tests shall

be conducted on a control (0%) and the following dilution

concentrations at a minimum: 100.0%, 50.0%, 25.0%, 12.5%, and 6.25%.

b. If control mortality exceeds 10% for either species in any test,

the test(s) for that species (including the control) shall be repeated.

A test will be considered valid only if control mortality does not

exceed 10% for either species.

2. The toxicity tests specified above shall be conducted once every

month until three (3) valid monthly tests have been completed, and once

every year thereafter for the duration of the permit, unless notified

otherwise by the permit issuing authority. These tests are referred to

as ``routine'' tests.

3. a. If unacceptable acute toxicity (an LC50 of 100% or less

occurs in either test species in any of the above- described tests

within the specified time) is found in a ``routine'' test, the

permittee shall conduct two additional acute toxicity tests in the same

manner as the ``routine'' test on the specie(s) indicating unacceptable

toxicity. For each additional test, the sample collection requirements

and test acceptability criteria specified in Section 1 above must be

met for the test to be considered valid. The first test shall begin

within two weeks of the end of the ``routine'' tests, and shall be

conducted weekly thereafter until two additional, valid tests are

completed. The additional tests will be used to determine if the

toxicity found in the ``routine'' test is still present.

b. Results from additional tests, required due to unacceptable

acute toxicity in the ``routine'' test(s), must be reported on the

Discharge Monitoring Report (DMR) Form for the month in which the test

was begun. Such test results must be submitted within 45 days of

completion of the second additional, valid test.

3. Background

The adoption of the State Underground Petroleum Environmental

Response (SUPER) Act of 1986 set standard procedures for the State of

Florida's Department of Environmental Protection (FDEP) and their

Division of Waste Management's Bureau of Waste Cleanup to regulate

during cleanup processes undertaken at all petroleum contamination

sites. The SUPER Act was amended on February 20, 1990, and is currently

referred to as Chapter 17-770, Petroleum Contamination Cleanup

Criteria.

Chapter 17-770 gives the FDEP authority over cleanup operations for

areas which have been contaminated by fuels from petroleum storage

systems. Chapter 17-770 also provides guidance for permittees in

preparing initial remedial actions (IRA's), contamination assessment

reports (CAR's), and remedial action plans (RAP's) while assessing and

delineating areas where suspected petroleum contamination has occurred.

In order to facilitate the authorization process for the potentially

large number of permittees who would be required to discharge treated

groundwater to surface waters of Florida, the FDEP requested that an

NPDES general permit be issued to cover these facilities in Florida.

The U.S. Environmental Protection Agency (EPA), after proposing a draft

permit on August 25, 1988 (53 FR 32442), issued a final NPDES general

permit on July 17, 1989 (54 FR 29986), to cover the facilities and

similar types of discharges associated with them. This NPDES General

Permit was modified on August 29, 1991 (56 FR 42736), to address

general dewatering for uncontaminated discharges of produced

groundwater and short term discharges from facilities with treated

groundwater. This modification also changed the number of the permit

from FLG040001 to FLG830000.

As of June, 1994, EPA has authorized over 350 facilities to

discharge under the general permit, and the FDEP estimates that there

are over 20,000 facilities that have reported suspected petroleum leaks

throughout the State of Florida. The current permit FLG83000 expired on

July 16, 1994, and numerous facilities are either discharging under

this permit or submitting Notices of Intent for coverage under this

general permit. Therefore, EPA Region IV is proposing to reissue the

NPDES General Permit No. FLG830000 to facilities in the State of

Florida to assist in permitting these types of activities. The

requirements for those facilities that were covered by the current

NPDES General Permit before July 16, 1994, will be continued in force

until reissuance of this general permit occurs. However, once

reissuance occurs, all facilities covered by this permit will be

required to submit a NOI requesting continued coverage under the

reissued general permit within sixty (60) days after reissuance of the

general permit. Permittees submitting NOI's after July 17, 1994, will

not be provided with a notification of coverage under the general

permit. These facilities will not be allowed to discharge until the

date which the reissued NPDES General Permit, FLG830000, becomes

effective, or until an individual permit is issued to the facility.

4. General Information for This Florida General Permit

This general permit places limitations on discharges from treatment

systems which are used to treat common contaminants found in petroleum

fuels and allows the permittee to expedite startup of a hydrocarbon

recovery system once a leak has been detected and groundwater has been

contaminated. The general permit also allows general dewatering for

uncontaminated sites. Normally, such a recovery system consists of

monitoring wells that are used for sampling and delineating plume

movement. Recovery wells, which may be vertical or horizontal, are used

to recover contaminated groundwater in the impacted area. The placement

of recovery wells is generally determined after consideration of

geologic conditions and groundwater movement in order to maximize

recovery of petroleum hydrocarbons. The rate of movement by the

contaminants is affected by the varying permeability and adsorptive

characteristics of the water-filled pore spaces and depth of the water

table. After the contamination reaches the water table, the free-

floating contaminant is usually pumped from the recovery wells to an

above ground storage tank. Additionally, vapor recovery systems are

often used to remove volatiles from the soil. The dissolved organics in

the contaminated water are pumped to an air stripper and treated using

packed-tower aeration and, when necessary, carbon adsorption. Both of

these treatment processes have proven effective in removing up to 99%

of the volatile compounds before discharge into surface waters.

The Florida FDEP and EPA Region IV estimates that of the sites for

which a RAP is prepared in any given year, a maximum of 100 facilities

may propose discharge to surface water under this general permit. In

order to allow hydrocarbon recovery operations to be performed without

processing individual applications for permit issuance, EPA proposes to

reissue this general permit to sources identified within the political

boundaries of the State of Florida.

This general permit may be used to authorize discharges of treated

groundwater and storm water incidental to groundwater cleanup

operations. Long term cleanups, over thirty (30) days, must have an

approved remedial action plan (RAP) before submitting a NOI to

discharge under this NPDES General permit. The RAP Approval Order must

be submitted with the applicant's NOI and is required before

authorizing cleanups over thirty (30) days. This permit is not limited

to cleanup operations funded by the State of Florida, but may cover all

such cleanup operations if the NOI requirements are satisfied.

5. Basis for Final Effluent Limits and Permit Conditions

The effluent limits for the general permit are based on treatment

technology data obtained from previous individual application requests.

The general permit has been written to require an effluent limit on

three (3) chemicals, i.e., benzene, naphthalene and lead.

Benzene is a potential carcinogen according to EPA 440/5-80-0180

and Florida has adopted a WQS for this parameter. However, the previous

technology-based effluent limit of 1.0 g/l is more stringent

than Florida's water quality standard of 71.28 g/l at (FAC 17-

302.530(9)), dated April 25, 1993; therefore, the more stringent

technology based limit, which is also protective of water quality, will

be included in the reissued permit. Based on the ``Ambient Water

Quality Document for Benzene,'' this maximum contaminant level for

benzene is well below the 10-6 risk factor of 40 g/l for

consumption of contaminated aquatic organisms. This limit of 1.0

g/l is also between the 10-5 risk factor of 6.6

g/l and 10-6 risk factor of .66 g/l for

consumption of contaminated water and aquatic organisms.

Most facilities have been able to meet the technology based

effluent limit for lead of 30 g/l, which is required since

older gasoline sites may have marketed fuels with leaded compounds

added in the form of tetraethyllead. Based on the ``Ambient Water

Quality Document for Lead,'' this limit is well below the current human

health standard of 50 g/l, which is protective of human health

against the ingestion of contaminated water and contaminated aquatic

organisms (EPA 440/5-80-057).

The naphthalene limit of 100 g/l was developed based on

FDEP petroleum contamination site cleanup criteria (17-

770.730(5)(a)2e), amended February 20, 1990. According to the ``Ambient

Water Quality Document for Naphthalene,'' acute and chronic toxicity to

freshwater aquatic life occurs at concentrations as low as 2300

g/l for the Rainbow Trout and 620 g/l for the Fathead

Minnow and would occur at lower concentrations among species that are

more sensitive than those tested. Also, according to the ``Handbook of

Environmental Data and Organic Chemicals,'' tainting of fish flesh

occurs for naphthalene near 1000 g/l. The petroleum site

criteria limit of 100 g/l for naphthalene is more stringent

than EPA's water quality document for this parameter and should provide

adequate protection for more sensitive aquatic organisms.

The pH requirements were established based on water quality

criteria at Florida Administrative Code (FAC) 17-303.530(52)(c), dated

April 25, 1993. For fresh waters and coastal waters, the pH of the

effluent shall not be lowered to less than 6.0 units for fresh waters,

or less than 6.5 units for marine waters, or raised above 8.5 units,

unless the permittee submits data during the NOI request confirming a

natural background pH outside of this range. If the natural background

of the receiving water, as revealed by sampling data from the permittee

in the NOI request, is determined to be less than 6.0 standard units

for fresh waters, or less than 6.5 standard units in marine waters, the

pH shall not vary below natural background or vary more than one (1)

unit above natural background. If natural background of the receiving

water, as revealed by sampling data from the permittee in the NOI

request, is determined to be higher than 8.5 units, the pH shall not

vary above natural background or vary more than one (1) unit below

natural background. The continuous monitoring for pH is an option

granted to the permittee and is based on Sec. 401.17 of the Clean Water

Act.

The permittee may request an individual permit to seek less

stringent end-of-pipe effluent limitations for benzene, total lead, and

naphthalene dependent upon resulting instream concentrations during

critical low flows of the receiving stream.

The groundwater reporting requirements for the parameters: TOC, pH,

the Total Recoverable Metals which include Mercury, Cadmium, Copper,

Lead, Zinc, Chromium (Hexavalent), Benzene and Naphthalene, to

determine if contamination exists from other sources are based on

Section 308(a) of the Clean Water Act. The screening values for TOC,

Benzene, and Naphthalene are based on the final August 29, 1991,

modification (56 FR 42739) and the standards for total recoverable

metals are based on the most current Florida Water Quality Standards

for total recoverable metals at FAC Section 17-302.530 [4-25-93]. As

with any petroleum fuel, other aromatic compounds will be present once

testing has occurred. Other volatiles will be present in untreated

groundwater in greater concentrations than benzene. Past experience in

treatment design has shown that these organics can be effectively

treated before discharging to surface waters. According to the

``Toxicant Profile for the ALKYL BENZENES,'' (Ethylbenzene,

Isopropylbenzene, Toluene, Xylene) prepared for Florida's DEP by the

Center of Biomedical and Toxicological Research at Florida State

University, levels for these ALKYL BENZENES of 100-200 g/l

were recommended for the protection of aquatic organisms and human

health. These recommendations are below EPA's ``Ambient Water Quality

Criteria'' documents recommendation for human health which suggest

levels of 1400 g/l to 14300 g/l for Ethylbenzene and

Toluene.

The recommended treatment technology of air stripping and, when

necessary, carbon adsorption, will reduce the benzene concentration to

below 1.0 g/l. Therefore, EPA will not impose specific limits

on the other pollutants which may occur since meeting the limits set in

this permit should reduce the other pollutants well below those levels

allowable based on Florida's water quality standards. Also, the

effluent shall not be lethal to more than 50% of appropriate fish or

invertebrate test organism in a 96-hour static renewal test. Whole

Effluent Toxicity (WET) monitoring tests performed by six (6)

facilities between May 8, 1991 thru March, 1994 indicated that these

effluents were toxic and, therefore, have the reasonable potential to

violate Florida's water quality standards at FAC Section 17-

4.244(3)(a). Because previous 48-hour static WET monitoring tests have

revealed that these effluents have the potential of being toxic,

toxicity testing requirements as authorized and required by 40 CFR

Section 122.44(d)(1)(iv), and contained in Part I, A.1 and A.2 and in

Part V have been included to ensure that the effluent from these

facilities conforms with the FAC. An LC50 of 100% or less in a

test of 96 hours duration or less will constitute a violation of FAC

(February 2, 1994) Section 17-4.244(3)(a) and the terms of this permit.

Since the recovery wells in most instances are placed in areas of

highest contamination, it is reasonable to conclude that the greatest

potential for toxicity should occur during the initial startup stages

of operation. Therefore, an initial frequency of once every month for

three (3) months is included in these requirements to indicate toxicity

and determine treatment performance of these facilities immediately

after commencement of discharge. If no toxicity is confirmed, the

frequency is then reduced to yearly since the permittee will be

required to meet effluent limitations and the potential for toxicity is

at a minimum. Failure to demonstrate compliance with the acute toxicity

requirement will constitute a violation of the terms of the permit.

The sample type for all biomonitoring is ``Grab'' in accordance

with Part V of this general permit.

The permittee is required to develop and implement a Best

Management Practices (BMPs) plan in conjunction with development of the

Remedial Action Plan required by FDEP. BMPs are actions or procedures

to prevent or minimize the potential for the release of toxic

pollutants or hazardous substances in significant amounts to surface

waters. Additionally, for long term cleanups, the permittee shall

develop a Pollution Prevention Plan which considers alternatives for

preventing and reducing impacts to surface waters in accordance with

Part IV. A.2 of this permit.

6. Treatment Technology

According to EPA's publication entitled ``Treatment of Volatile

Organic Compounds in Drinking Water,'' a drinking water research

experiment was conducted on spiked water using one organic volatile and

then by combining two volatiles. The experiment used aeration as the

treatment process. It was discovered that no difference was observed in

treatment efficiency when applying aeration to one organic chemical or

a combination of volatiles. In this particular experiment an overall

efficiency of 92% was obtained. Most petroleum fuels consist of a

combination of volatiles and aromatics, each different, based on

additives included during refining of the fuel. In case studies

revealed in the Environmental Science and Engineering's document ESE

No. 84-912-0300, packed tower aeration utilizing different packing

materials, varying flow paths and air-to-water ratios have been proven

effective in removing over 99% of the volatiles. Some particular

compounds are not as easily air-stripped as others which would

necessitate the need for a combination treatment design used in

conjunction with aeration. Carbon adsorption has been proven effective

in removing organics from water until the influent concentration is in

equilibrium with the effluent and the organics no longer adhere to the

carbon surface. Adsorption has been used successfully in removing less

volatile compounds of higher molecular weight. Other remediation

techniques currently being deployed include vapor recovery systems and

bioremediation which enhances biological activity.

According to (EPA 570/9-84-005) entitled ``Adsorption Techniques in

Drinking Water Treatment'' the efficiency of carbon adsorption was

proven effective during a case study in Hialeah, Florida at the Preston

water treatment plant. In this study, groundwater from a drinking water

aquifer was spiked with higher molecular weight extractables before

treating the water with granular activated carbon. It was found that

more than 90% removal of the spiked compounds was obtained. The

combination of air-stripping with adsorption usually extends the

adsorptive life of the activated carbon and leads to more efficient

treatment, but is not always required or recommended in every

situation.
