Subject: Permit No. NCS000136
Mallinckrodt Chemical, Inc.
Wake County
Dear Mr. Mattison:
In accordance with your application for a stormwater discharge permit received on October
29, 1992, we are forwarding herewith the subject state - NPDES permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-2.15 .1 and the Memorandum
of Agreement between North Carolina and the US Environmental Protection agency dated
December 6, 1983.
The following responses are offered to the comments received on the draft permit in a letter
dated July 26, 1994, from Vicky Will, Environmental Affairs Manager.
The first issue raised in the comments was a request for an additional period of time for
accomplishment of secondary containment systems. Due to the size of Mallinckrodt's facility and
the number of storage areas you.requested that 24 months be allowed for the accomplishment of
this task. The request is reasonable and the final permit has been amended to allow 24 months.
In response to the question of the applicability of the requirements of the Preventative
Maintenance and Good Housekeeping Program and the request that the wording be modified to
specifically refer to plant equipment and/or systems relating to the stormwater requirements, the
Division concurs and the final permit has been so modified.
The third issue concerns the requirements for twenty-four hour reporting and the request that
the wording be changed in Part II, Section E, 5(b) and 5(c), to provide that the twenty-four hours
for reporting begin with the receipt of information or data indicating non-compliance. This
provision is addressed adequately in 5(a) of this Section where the requirements state "within 24
hours from the time the permittee became aware of the circumstances..." Paragraphs 5(b) and 5(c)
further clarify this same Section and the twenty-four hours referred to in all parts of this Section
are "from the time the permittee became aware of the circumstances." Hopefully; this clarification
satisfies Mallinckrodt's concern with this issue.
The fourth item requested that the correct name of the company be listed as the permittee,
Mallinckrodt Chemical, Inc. The final permit has been so modified. The Division received a
check (Check #0077002890 on July 13, 1994 for $100) and request for a change in ownership
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] .FAX [phone]
An Equal Opportunity Affirmative Action Employer 5T% recycled/ 10% post -consumer paper

concerning this change in name. Since the permit was still in draft form, no change fee was
required and the check is returned to you herein.
The final issue is that the upgradient drainage entering the Mallinckrodt property in Drainage
Area #4 may adversely affect the quality of the stormwater leaving the Mallinckrodt site. The
Division concurs with the proposal to collect upgradient and downgradient stonnwater samples at
each sampling instance. However, Mallinckrodt shall be required to report both the upgradient and
downgradient analytical results as well as reporting the differences. Assessment of the quality of
stormwater leaving the Mallinckrodt site will be based on the contribution to the pollutant load
calculated by the difference.
By copy of this letter I am asking that our Raleigh Regional Office investigate the potential
that unpermitted nonstormwater discharges are occurring upstream from and impacting the
Mallinckrodt site and advise you of their findings. Your assistance is appreciated in bringing this
matter to our attention. I hope I have adequately addressed your comments.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611
-7447. Unless such demand is made, this decision shall be final and binding.
Please take notice this permit is not transferable. Part Il, B.2. addresses the requirements to
be followed in case of change.in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Environmental Management or permits required by the Division of
Land Resources, Coastal Area Management Act or any other Federal or Local governmental
permit that may be required.
If you have any questions concerning this permit, please contact Bill Mills at telephone
number 919/733-5083.
Sincerely,.

DISCHARGES
SECTION A, FINAL LIMITATIONS AND CONTRQLS FOR STORMWATER DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified below.
1. Stormwater Pollution Prevention Plan
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plafi. This Plan shall be considered public information in accordance with Part II, Standard
Conditions, Section E.S. of this permit. The Plan shall include, at a minimum, the following
items:
a. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system; the
name of the municipality and the ultimate receiving waters, and accurate latitude
and longitude of the point(s) of discharge,
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
activities occurring in the drainage area, building locations and impervious surfaces,
and the percentage of each drainage area that is impervious. For each outfall, a

Permit No. NCSOOO1 36
2. Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Environmental Management.
a. If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to he sampled, the permittee may petition the Director for
representative outfall status. if it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge outfall locations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
C. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative s^torrn event (See Part 11,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d . Samples analyzed in accordance with the terms of this permit shall be submitted on forrns
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
C. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
f. This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
(1) All other discharges that are authorized by a non-stormwater NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant flushings, water from footing drains, flows from riparian
habitats and wetlands.
(3) Discharges resulting from fire -fighting.
Page 7

Permit No. NCS000136
If the storm event monitored and reported in,accordance with this permit coincides with a
non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

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.
It shall not be a defense for a perininee 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.
a. Definitions
(1) "Bypass" means the known diversion of stormwater from any portion of a
stormwater control facility including the collection system, which is not a
designed or established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property,
damage to the control 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 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
affect of the bypass.

(2) Unanticipated bypass. The perminee shall submit notice within 24 hours of
an unanticipated bypass as required in Part H, E. S. of this permit. (24-
hour notice).
d. Prohibition of Bypass
Bypass is prohibited and the Director may take enforcement action against a
permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury or severe
property damage;
(2) There were no feasible alternatives to the bypass, such as the use of
auxiliary control facilities, retention of stormwater or maintenance during
normal periods of equipment downtime or dry weather. This condition is
not satisfied if adequate backup controls 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
(3) The permittee submitted notices as required under Paragraph c. of this
section.
The Director may approve an anticipated bypass, after considering its adverse
effects, if the Director determines that it will meet the three conditions listed above
in Paragraph d. of this section.
4. Upset
a. Definition
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the permittee. An upset does
not include noncompliance to the extent caused by operational error, improperly
designed treatment or control facilities, inadequate treatment or control facilities,
lack of preventive maintenance, or careless or improper operation.
b. Effect of an Upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with technology based permit effluent limitations if the requirements of paragraph c.
of this condition are met, No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
C. Conditions Necessary for a Demonstration of Upset
A permittee who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs, or other
relevant evidence that . -
(1) An upset occurred and that the permittee can identify the cause(s) of the
upset;

Individual Stormwater Page A13
(2) The permitted facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 5. (b)
