A. Summary of Work: These specifications cover pilot hole drilling and the construction, testing and sampling of one (1) new Lower Patapsco aquifer production well (Cliffton Well No. 5) for the Charles County Department of Public Works. The work includes well construction, development and testing, and the installation of a new high efficiency submersible well pump and motor and a pitless adapter unit.

B. Background/Purpose: The purpose of the project is to provide additional capacity

to the Cliffton Service Area from the Lower Patapsco aquifer to help ensure operational flexibility.

C. Project Sequence: The Work described in these technical specifications shall be

undertaken in the following general steps:

1. Mobilize to the site with suitable mud-rotary drilling and project support equipment.

2. Install temporary 20-foot tall sound barriers along a portion of the western boundary between the existing well house and the adjacent property.

3. Drill a pilot hole to the base of the Lower Patapsco aquifer at an estimated depth of approximately 1,100 feet bls.

4. Log the uncased pilot hole with geophysical logging equipment. 5. Perform a sieve analysis on formation samples collected from the Lower

Patapsco aquifer while drilling the pilot hole. 6. Submit the proposed well construction design to the Owner’s

Representative for review and approval. 7. Drill and install a double-cased (lap construction) Lower Patapsco aquifer

production well with 12-inch diameter steel well casing and 6-inch diameter stainless steel well screen and inner casing.

8. Thoroughly develop, test pump and sample the new well. 9. Dispose of all drill cuttings, drilling fluids, initial development water as

further described in these specifications. 10. Furnish and install a pitless adapter on the new well. 11. Furnish and install a new 350 gpm stainless steel submersible pump and

stainless steel motor in the well with 6-inch diameter threaded and coupled (T & C) steel column pipe.

12. Conduct a step-pressure operational test of the permanent well pump and motor.



13. Demobilize all well drilling equipment, remove the temporary sound barriers and restore the site.

The Work is to be undertaken on a combination lump sum/unit price basis with provision for greater or lesser quantities as necessary based on actual installed quantities as reported by the Contractor and verified in the field by the Owner’s Representative. A sketch of the proposed new production well is shown in Figure 1.

D. Scope of Work: The Work to be done hereunder includes the furnishing of all labor, equipment, materials, and appurtenances, unless specifically exempted, necessary for the complete and satisfactory construction, development, disinfection and testing of the proposed production well, and for furnishing and installing a new submersible well pump, motor, and pitless adapter as described under the following paragraphs. The Contractor will be required to provide all temporary electrical power necessary for the completion of the Work as specified, including power to perform the step-rate and 24-hour constant rate pumping tests in the new well and the final step-pressure pumping test on the permanent pump.

1.02 SITE LOCATION AND LAYOUT

A. Well Location: The well site is located north of Cliffton Drive, approximately 4,000 feet west of its intersection with U.S. Highway 301 on an existing tract of Charles County-owned land known as Tax Map 79, Parcel 119 (Figure 2). NOTE: Due to limited visibility along Cliffton Drive the Contractor will not be allowed to park vehicles along the road and must provide adequate safe parking within the boundaries of the well site for all his construction vehicles and equipment.

B. Surface Conditions: The well site has sufficient clear space to support drilling

operations and for staging materials and equipment. As part of a future project a new elevated storage tank will be erected at the site, north of where the new well is to be drilled.

At present the site contains numerous small-medium trees and some medium-heavy brush. The Contractor shall clear only that portion of the lot necessary to facilitate drilling operations and install and maintain for the duration of the project a suitable stabilized construction entrance, temporary stone access road, and work



pad. Upon completion of the project the construction entrance, stone access road and work pad must be removed and the site restored to the same condition as that which existed prior to the start of construction.

The proximity of the new well to the proposed location of the new elevated storage tank to be constructed at the site dictates that portable above-ground mud tanks must be utilized to handle the fluids to drill the new well. The location of any in-ground pick-up pits must be approved in advance by the Owner to ensure that their placement does not conflict with any future construction that will take place at the site.

C. Contractor’s Responsibility: The Contractor shall satisfy himself regarding all local conditions affecting his Work by making personal investigations and using his own knowledge and experience of the area and of well construction and testing practices. The Contractor shall inspect the well site and make all necessary arrangements for physical access to and from the work areas.

All drilling fluids, drill cuttings, and initial well development water must be hauled away and disposed of off-site in a manner approved by the Owner. The Contractor shall be responsible for the proper disposal of all water removed or pumped from the wells during this project. During the pumping tests non-sediment laden, slightly turbid water, as determined by the Owner may be disposed of at the site in an approved manner.

The Contractor is responsible for obtaining any local, state or federal discharge permits that may be required to facilitate the disposal of all water generated as part of this project, including, but not necessarily limited to, General Discharge Permit 11-HT as further described.

1.03 NOISE CONTROL AND LIGHTING

A. Temporary Sound Barrier: Due to the proximity of the project site to a residential area, the Contractor shall install and maintain adequate noise control measures to the Owner’s satisfaction for the duration of this project. The Contractor shall construct a solid noise barrier along a portion of the western edge of Parcel 119 as shown on the plans.

In addition to the noise control barriers specified below the Contractor shall

employ other noise control measures as necessary, such as the use of special silencers, etc., to achieve compliance with the applicable Charles County Noise Control Ordinance. Specific requirements of the noise barrier wall are as follows:



1. Noise barrier walls shall be a minimum of 20 feet in height, or greater if required to achieve compliance with the noise control standards. The barriers shall extend as shown on the plans, a distance of approximately 150 feet.

2. The noise barrier wall shall be constructed of 1-inch thick (minimum) plywood weighing not less than 3 pounds per square foot.

3. There shall be no gaps between adjacent noise barrier wall panels. A minimum of 6-inch wide strips of 1-inch thick plywood shall be used to cover the seams between adjacent noise barrier panels.

The Contractor shall submit shop drawings for the noise barrier wall to the Owner’s Representative for approval prior to constructing the barrier. If the noise control barriers (and other measures undertaken by the Contractor) to mitigate the noise at the site prove to be inadequate in the field the Contractor shall take whatever additional steps are necessary to provide satisfactory noise abatement to meet the specified sound levels requirements at no additional cost to the Owner. Upon completion of well construction activities the Contractor shall remove the temporary noise barrier walls as part of his overall project demobilization activities.

B. Lights in the Work Area: All lighting at the project site provided by the Contractor must be concentrated in the work area and shall not illuminate or disturb the adjacent residential property.

method. The drilling fluid shall be maintained at such weight and viscosity to carry the cuttings out of the drilled hole and to prevent caving within the drilled hole.

C. Pilot Hole Sediment Sampling: During drilling of the pilot hole sediment samples

shall be collected from ground surface to the total depth drilled as follows:

1. Method of Collection: The Contractor shall obtain return flow (ditch) samples by removing from the circulating drilling fluid a representative sample of the formation by either collecting the samples in a cutting sample box, sediment shaker, a baffle in a ditch, or in some other approved manner. Provisions shall be made to determine the exact depth at which the samples are being collected.

The Contractor shall be required to drill the specified sample interval (10-foot intervals from ground surface to the top of the water bearing formation and 5-foot intervals thereafter, or at any pronounced change of formation) and then allow adequate time for a representative sample to be pumped up the borehole to the ground surface before advancing the pilot



hole to a greater depth. Immediately after collection the Contractor shall thoroughly wash each sample with clean water before placing them in containers. Special care shall be taken when washing the samples to preserve the integrity of each formation sample.

2. Collection Interval: Formation samples will be taken at 10 foot intervals,

or at any pronounced change of formation, from ground surface to near the top of the Lower Patapsco aquifer a depth of approximately 1,000 feet bls. Beginning at that depth samples shall be collected at 5 foot intervals and at any pronounced change of formation until the full thickness of the Patuxent aquifer has been penetrated. Special care should be used when collecting samples from the aquifer.

3. Number of Samples: One representative sample shall be obtained from

each 10-foot sampling interval, and at least two representative samples shall be obtained from each 5-foot sampling interval.

4. Marking Samples: Immediately after retrieval the formation samples shall

be placed in suitable containers, securely closed to avoid spillage and contamination, and clearly labeled in a permanent manner with at least the following information:

A. Location of the well. B. Name or number of the well. C. Depth interval represented by the sample. D. Date collected.

5. Delivery of samples: One set of samples collected while drilling the

aquifer shall be delivered to a qualified testing facility so that sieve analyses can be performed. The remaining set of samples shall be safely stored on-site by the Contractor until they are accepted by the Owner for additional processing.

3.03 ABANDONMENT OF THE PILOT HOLE (IF REQUIRED)

A. General Statement: Depending on the results of pilot hole drilling and geophysical logging the Contractor will either be asked to construct a production well or abandon the pilot hole. Well construction is covered in the next section of the specifications. If the pilot hole is to be abandoned it shall be done so as to



meet all applicable requirements of the State of Maryland regulations. 3.04 PRODUCTION WELL CONSTRUCTION

A. Description of Production Well Construction: The production well is to be completed with a 12-inch diameter steel well casing set to an approximate depth of 1,000 feet bls, and finished with 6-inch diameter stainless steel inner casing and well screen set in the Lower Patapsco aquifer. The new well is to have maximum efficiency and will be used for a potable water supply.

B. Method of Drilling: Drilling for the production well shall be undertaken using the

hydraulic mud rotary method for the pilot hole, and also for reaming the pilot hole to accept the outer well casing. The drilling fluid shall be maintained at such weight and viscosity to carry the cuttings out of the hole and to prevent caving within the drilled hole. After the well casing is set and cemented in place either the hydraulic mud rotary or reverse rotary drilling method may be utilized to ream the formation area to accept the well screen and gravel pack.

Once the 12-inch diameter steel outer casing is set and grouted in place, the Contractor will pump the drilling fluid out of the mud pits and completely flush out the casing with clear water. Effluent from these operations shall be disposed of off-site as previously specified. After removal and disposal of the drilling fluids the Contractor will mix new mud (if drilling by the mud rotary method) or fill his tanks with clean water (if using a reverse drilling method) and proceed drilling through the formation areas to be screened.

C. Selection of Screen Dimensions: The well screen slot size, configuration, depth

interval, and gravel pack size will be selected by the Contractor and approved by the Owner based on all previous work and the intent of these specifications. The Contractor shall check the driller’s logs, geophysical logs, and sieve analysis from the pilot hole to reach a final recommendation concerning screen slot size and placement.

The total estimated length of stainless steel inner casing and screen shall be

approximately 200 feet. For bidding purposes this shall include 65 feet of well screen; 40 feet of blank casing; 10-foot sump; 10-foot transition blank; 5-foot relief screen; and 70 feet of lap pipe.



D. Drilling to Set Well Casing: The drilled hole for the 12-inch diameter steel well casing shall be reamed to a minimum diameter of 21 inches from ground surface to a depth of approximately 1,000 feet bls. The 21-inch diameter hole is necessary to allow sufficient room for the well casing and 2-inch diameter external monitoring pipe. Once the 12-inch diameter casing has been installed and grouted in place, the hole for the 6-inch diameter well screen and blank sections will be drilled to a nominal diameter of 11 inches.

E. Installation of the Casing: The sections of 12-inch diameter steel well casing

shall be set in the drilled hole in such a manner that they will be round, plumb and true to alignment. Casing joint connections are to be welded in accordance with the latest procedures set forth by the American Welding Society and as previously described.

The 2-inch diameter stainless steel monitoring pipe shall be attached to the outside of the 12-inch diameter well casing to a depth and in a manner as previously described, and installed as the casing is lowered into the drilled hole.

F. Alignment Test: The test for alignment in the 12-inch diameter steel well casing

shall be made after the casing has been installed in the drilled hole and before grouting the annular space. Alignment shall be tested by lowering into the well a 40-foot long section of 4-inch diameter (or larger) pipe with guides on each end and in the middle. The outer diameter of the guides shall not be more than ½-inch smaller than the diameter of the casing being tested. The guides shall be a minimum of one (1) foot long. The alignment tool shall be lowered into the well on a cable. Installation of the alignment tool on rigid pipe will not be allowed. The steel outer casing shall be tested for alignment over its entire length.

G. Results of Alignment Test: Should the alignment tool fail to move freely

throughout the length of the casing being tested, the alignment of the well shall be corrected by the Contractor at his own expense. If the Contractor fails to correct the faulty alignment, the Owner may refuse to accept the well and require that another well be constructed at another location on the property. The inside and outside of the existing casing or borehole, if the casing is removed, would then be properly filled and sealed at the Contractor’s expense. The Owner may waive the requirements for alignment if, in his judgment, the defect is due to circumstances beyond the Contractor’s control



and/or the utility of the completed well will not be materially affected.

H. Installation of Grout: The annular space between the drilled hole and the 12-inch diameter steel well casing shall be sealed by pressure grouting from the bottom of the casing to ground surface. This shall be accomplished either by pumping grout through a tremie pipe set inside the pressurized well casing to near the bottom of the 12-inch diameter steel casing (Halliburton method), or by pumping grout through a tremie pipe set on the outside the casing to near the bottom of the well casing (stage grouting), and retrieving pipe after each grout lift has been pumped.

In either case, sufficient circulation shall be established in the annular space prior to the start of grouting operations by pumping conditioned drilling fluid or clean water through the tremie pipe to clear obstructions in the annular space. After circulation has been established in the borehole, without significant interruption the entire annular space shall be filled with neat cement grout pumped down the tremie pipe under pressure. Pumping shall continue until cement returns are observed at the ground surface in the return ditch. No work shall be allowed to be performed on the well for at least 24-hours after completion of grouting operations to allow adequate time for the cement grout to set. The Owner must be notified a minimum of 24 hours prior to the start of grouting operations and shall be present at site to witness the presence of grout returns at the ground surface.

I. Drilling to Set Well Screen and Blank Sections: The drilled hole for the 6-inch

diameter stainless steel well screen and blank sections shall measure not less than 11 inches in diameter from the bottom of the 12-inch diameter well casing to a depth of approximately 1,100 feet bls. The 11-inch diameter hole for the screen line shall be drilled after the 12-inch diameter casing has been installed and grouted in place.

J. Installation of Well Screen and Inner Casing: The 6-inch diameter stainless steel

well screen, blank sections, and inner casing shall be installed in the 11-inch diameter drilled hole in such a manner that the sections remain round, plumb and true to alignment. Centralizers will be installed on the screen and riser pipe at intervals as previously specified.

K. Installation of Gravel Pack: After the riser pipe and well screen are properly and

securely positioned in the well, the Contractor shall furnish and install a gravel pack in the annular space between the well casing and screen and the drilled hole.



The gravel pack material shall be composed of graded gravel having a hard, clean, smooth surface as previously described in Section 2.07. The size of the gravel shall be selected in accordance with the character of the water-bearing formations and the design of the well screen. The Contractor shall be responsible for ensuring that the gravel pack material is adequately disinfected during installation. The gravel pack shall be placed adjacent to the well screen using the tremie pipe method so that the entire annular space between the screen and the borehole to a point approximately five (5) feet below the top of the 6-inch diameter lap pipe is uniformly filled with gravel. The borehole shall be continually flushed with clean water to remove drilling sediments and natural clays prior to and during installation of the gravel pack.

3.05 WELL DEVELOPMENT

A. Development Methods: A method of development will be used which will result in the removal of fine material in the vicinity of the well screen, increase the material porosity of the undisturbed formation and remove the mud cake and drilling fluid from the boreholes. This is to be accomplished with a method of development which will cause a reversal of flow through the well screens, combined with pumping, to remove color and fine materials. Acceptable development methods may include, but are not limited to, double-disc surge block agitation and airlift pumping, or high velocity jetting and pumping.

The well screen shall be evenly developed over its entire length in isolated 5 foot

increments starting at the deepest set screen interval and progressing systematically to the upper-most screen. Development shall include at least 2 hours of vigorous development for each 5-foot interval. Development by the above described methods must be done prior to the installation of the test pump.

3.06 SUPPLEMENTAL WELL DEVELOPMENT

A. Checking Efficiency During Development: The Contractor may, as part of this

Work, conduct tests periodically to check the progress of development and well efficiency. All of these tests shall be included in the base bid amount of the well.

B. Additional Development: Development shall be sufficient to provide a minimum

acceptable efficiency for the well as defined under the Acceptance Standards contained in these specifications. After the pumping tests the Contractor may continue to develop the well to allow the well to reach the minimum



requirements. All additional development and re-testing necessary to meet the Acceptance Standards will be at the Contractor’s expense.

WATER SUPPLY PROGRAM

SAMPLING PROCEDURES FOR NEW PUBLIC SUPPLY WELLS

The Water Supply Program is frequently asked questions about required testing for new water

supply wells for community or non-transient noncommunity water systems. We have

summarized our current requirements in this document. The tests must be completed and

submitted to the Water Supply Program (WSP) for approval prior to placing a well in operation.

This testing is also required prior to issuance of MDE's Water Treatment Facilities construction

permit. The samples must be collected by a State-certified sampler and the tests performed

by a State-certified lab using approved drinking water methods. The labs are required to

submit data using MDE self-monitoring report forms for all primary standards. Please organize

the data according to the headings A through H described below. It is important that the sample

be representative of the water in the aquifer, that there is no contamination from water used

during drilling or well development, and that the well is fully developed prior to sample

collection. Stable turbidity, temperature, pH and conductivity are good indicators to determine

when to sample. The well and any down-hole equipment must be disinfected and dechlorinated

prior to bacteriological sampling.

There often are site specific conditions which could warrant testing additional parameters, testing

certain parameters over an extended period or testing a more limited number of parameters.

Requests for reduction in testing parameters must be made in writing with reasons provided. If

the new well is located in an existing well field or replacing an existing well the required testing

may be reduced.

For proper sampling containers, preservation and holding times consult with an approved

laboratory. Testing for all parameters to be performed on unfiltered samples.

The following parameters are required to be tested for new sources:

A. Bacteriological - test for concentration (MPN) of total coliform and fecal coliform, if total

coliform is present (include check for chlorine residual)

Final bacteriological testing will be required for raw and finished water after the water

treatment facility has been constructed and disinfected.

B. Turbidity, Temperature, pH, Conductivity - it is often useful to determine if the pH rises

with stirring. Report initial and final values.

C. Secondary Constituents

1) Chloride 6) Calcium

2) Alkalinity 7) Iron

3) Hardness 8) Manganese

4) Total Dissolved Solids 9) Zinc

5) Sulfide 10) Color

11) free CO2 required for sources with pH less than 6.0

2

Primary Standards - Chemical & Radiological (See Reporting forms for contaminant lists)

D. Inorganic Compounds (IOCs)

Test for all contaminants listed on Inorganic Self-Monitoring Report

(IOC/MDE/WMA/COM.008 – Revised 7-02) except as noted below. Detection levels for

testing are in every case 1/2 the MCL or less and can be found in 40 CFR 141.

Nitrate samples will be required within 3 months prior to issuing a Certificate of

Potability for all sources when levels are 5 mg/l or greater.

1) Also test for lead and copper. Detection level for lead is 5 ppb and is 50 ppb for

copper.

2) Asbestos and cyanide testing are required for sources vulnerable to these

contaminants, as determined by the Water Supply Program.

E. Volatile Organic Compounds (VOCs)

Test for all contaminants listed on Volatile Organic Self-Monitoring Report

(VOC/MDE/WWMA/COM.009 – Revised 7-02). Required detection level for all VOC

contaminants is 0.5 parts per billion (ppb).

F. Synthetic Organic Compounds (SOCs)

The SOCs are listed on Organic Self-Monitoring Report (SOC/MDE/WMA/COM.007 –

Revised 7-02). Wells are classified by the WSP to be in confined or unconfined aquifers.

Testing for SOCs is not required for wells in confined aquifers.

Testing for SOCs is required for wells in unconfined aquifers. Diquat, dioxin, endothall

and glyphosate testing is not required at unconfined sources. Dioxin testing, however may

be required at unconfined sources near military installations or superfund sites.

G. Radiological Contaminants

1) Gross alpha particle radioactivity - if the gross alpha particle is above 5 pCi/liter

the sample must also be analyzed for radium-226 and radium-228.

2) Man-made radioactivity is only required when a supply is potentially affected by a

source of radioactive contamination.

Testing for radon is required for wells in Baltimore, Carroll, Cecil, Frederick, Harford,

Howard, Montgomery and Washington Counties.

H. Testing for Surface Water Influence

Monitoring over an extended period is required if the source is likely to be under the

influence of surface water. Wells within 500' feet of a surface water source with less than

50' of casing and all wells in carbonate rock formations are required to be tested

following rainfall events. A detailed sampling protocol is available from the Water

Supply Program.

Contact the Water Supply Program (410-537-3714) with any questions.

APPLICABILITY AND COVERAGEPursuant to the provisions of Title 9 of the Environment Article, Annotated Code of Maryland, and the provisions of the Federal Clean Water Act (CWA), 33 U.S.C. §1251 et seq. and implementing regulations 40 CFR Parts 122, 123, 124, and 125, the Maryland Department of the Environment, hereinafter referred to as the “Department”, hereby authorizes operators located in the state of Maryland, who have submitted a notice of intent (NOI) and received written approval from the Department, to discharge wastewater from hydrostatic testing and related discharges described herein to waters of the state of Maryland in accordance with the eligibility requirements and other conditions set forth in this permit and consistent with the permittees’ NOI on file with the Department.

A. Geographic�Coverage�This permit covers discharges to surface or groundwater located within the territorial boundaries of the state of Maryland.

B. Eligible DischargesThis permit covers the following discharges:

1. Treated tank bottom wastewater from petroleum (i.e., gasoline, kerosene, fuel oil, ‘Number 6 oil’ and aviation fuel only) storage tanks to surface waters;

2. Wastewater from the disinfection (only disinfection agents containing bromide or chloride are authorized) or hydrostatic testing of pipes, pipelines or tanks;

3. Wastewater from draining or flushing of fire control systems;

4. Discharges from potable water systems resulting from the overflow, flushing, disinfection, hydrostatic testing, mechanical cleaning, or dewatering of vessels or structures used to store or convey potable water;

5. Untreated “water” in excess of 10,000 gallons per day as a monthly average from water storage or distribution systems, including but not limited to hydrogeologic/aquifer/well head yield-testing; and

6. Storm water discharges from petroleum storage tank containment structures.

C. Ineligible DischargesThe following discharges are not eligible for coverage under this general permit:

1. Discharges of any type from oil terminals;

2. Tank bottom wastewater discharges to groundwater of the state;

3. Wastewater from the chemical cleaning of storage tanks, pipes and pipelines; and

4. Wastewater discharges to groundwater that, before treatment, contain concentrations of benzene, lead, or other substances in excess of Toxicity Characteristic Leaching Procedures (TCLP) concentrations as defined in COMAR 26.13.02.14.

D. No Permit Required No discharge permit is required for the discharge of water from impoundments formed by the damming of natural drainage paths, or for the discharge of any untreated "waters" less than 10,000 gallons per day, as a monthly average.



E. Individual Permit or Another General Permit Required

1. If the Department determines that a discharge may cause an in-stream exceedance of water quality standards, the Department may require additional actions, including an application for an individual permit.

2. The Department may require any person authorized by this permit to apply for and obtain an individual state or state/NPDES discharge permit or obtain coverage under another general permit. If an owner or operator fails to submit, in a timely manner, an application for the Department-required individual state or state/NPDES discharge permit or a Notice of Intent (NOI) for another general permit as established by this condition, the applicability of this permit to the owner or operator is automatically terminated. Effective at the end of such day that was specified by the Department for the application or NOI to be submitted this permit is terminated and the permittee’s continuance of discharges that are covered by this permit is no longer authorized.

3. Any person authorized by this permit may request to be excluded from coverage under this permit by applying for an individual state or state/NPDES discharge permit or requesting coverage under another general permit. The Department may grant this request by issuing an individual state or a state/NPDES discharge permit or by granting coverage under another general permit, if the reasons cited by the owner or operator are adequate to support the request.

4. When an individual state or state/NPDES discharge permit is issued to a person for discharges otherwise subject to this permit, the applicability of this permit to the permittee is automatically terminated on the effective date of the individual state or state/NPDES discharge permit.

5. If there is evidence indicating potential or realized impacts on water quality due to any activity covered by this permit, the owner or operator of the discharging facility may be required to obtain an individual state or a state/NPDES discharge permit or coverage under another general permit.

6. If a person otherwise covered under this permit is denied coverage under an individual state or a state/NPDES discharge permit, the denial automatically terminates on the date of the denial, the person's coverage under this general permit, unless otherwise specified by the Department.

7. The Department may process an NOI as an application for an individual permit if site specific conditions do not allow registration of the facility under the general permit without compromising water quality. Such circumstances may occur when a permittee proposes to discharge to impaired waters, with or without an existing Total Daily Maximum Load (TMDL), or for discharges to high quality waters.

F. Termination of Permit

1. The Department may terminate coverage under this general permit for an existing permittee if the Department finds that:

a. The NOI contained false or inaccurate information;

b. Conditions or requirements of the discharge permit have been or are about to be violated;

c. Substantial deviation from plans, specifications, or requirements has occurred;

d. The Department has been refused entry to the premises for the purpose of inspecting to insure compliance with the conditions of the discharge permit;



e. A change in conditions exists that requires temporary or permanent reduction or elimination of the permitted discharge;

f. Any state or federal water quality stream standard or effluent standard has been or is likely to be violated; or

g. Any other good cause exists for terminating coverage under this permit.

2. If the Department terminates permit coverage as a result of one of the conditions listed in Section F-1 above, the permittee must apply for an individual permit immediately. The permittee must also cease any and all activities listed in PART I - Section B. until coverage is granted under an individual permit. If there are periods of discharge between the termination of the general permit and the effective date of the individual permit, the facility operator and owner are accountable for those discharges and any violations of state and federal law are subject to penalty as detailed in PART VI.

3. Any permittee not requesting termination of permit coverage remains responsible for meeting all permit requirements, including monitoring and reporting. A permittee should request permit termination by submitting a Notice of Termination (NOT) MDE/WMA/PER.005 form (http://www.mde.state.md.us/) if:

a. All discharges have permanently ceased.

b. For discharge of storm water from containment structures, all product has been permanently removed from storage tanks and all residual contamination in the containment structure has been removed.

G. Authorization

1. To be authorized to discharge under this general permit, a person is required to submit an NOI in accordance with the requirements of PART III of this permit, pay the required fee, receive notification from the Department of registration and comply with the terms and conditions of this permit. Coverage under this permit is effective on the date that the NOI is accepted by the Department, provided the NOI fee has been paid to the Department in accordance with the terms stipulated in PART III below. A person who submits such an NOI, is notified of its acceptance by the Department, complies with the terms and conditions of this permit, and pays the required fee, is authorized to discharge under the terms and conditions of this general permit.

2. If the NOI fee is paid by check which does not clear for any reason, the applicant will be given 30 calendar days to make proper payment, including any interest and other charges. If payment is not received by the 31st calendar day, coverage under this permit shall be considered void from the outset. The permittee should save the cancelled check, a copy of the completed NOI, and the registration letter from the Department. These documents shall be provided to the Department upon request.

H. Transfer of Authorization

1. The authorization under this permit is not transferable to cover a change in facility location.

2. The authorization under this permit is not transferable to any person except in accordance with this section.



3. Authorization to discharge under this permit may be transferred to another person if:

NOTE: The temperature difference shall be measured as follows: The discharge shall not cause the temperature of the receiving waters to exceed the water quality criteria described above, or if the ambient stream temperature already exceeds those criteria, then the discharge shall not cause a measureable rise in the receiving water temperature beyond a mixing zone. The allowable mixing zone for temperature in still water is 50 feet radially from the outfall and in flowing water, 50 feet from the discharge point (outfall) in the direction of flow at the time of measurement. To quantify these variables, this permit expresses the results as “temperature difference”, which is the arithmetic result of subtracting the effluent temperature or the temperature at the effluent first, and if the temperature is less than or equal to the stream standard, no in-stream measurements are necessary and the permittee shall report “<0” on the discharge monitoring report (DMR).

b. All used tanks, pipes or pipelines shall be cleaned before being filled with test water. All wastewater and removed solids resulting from cleaning operations shall be properly disposed in a manner which will not result in a discharge to waters of the state.

c. If the wastewater discharge is solely to groundwater, the above effluent limitations and monitoring requirements are waived except for flow and oil and grease.

d. The permittee shall take all necessary measures to prevent erosion damage during the discharge. Any gullying greater than six inches in depth is considered excessive erosion. If the discharge is onto normally dry land or a dry drainage channel, these preventive measures may include, but are not limited to, discharge via a diffuser, discharge into riprap, discharge into a splash barrier, and flow rate controls. If the discharge is directly into flowing or standing water, preventive measures include flow rate control and locating the point of discharge in the receiving water at a sufficient depth to avoid bottom scour.

e. If water for testing purposes is appropriated from surface or groundwaters of the state, the permittee shall obtain, if necessary, a water appropriation permit from the Department. If water is withdrawn from surface sources for testing purposes, the raw water intake shall be placed off the bottom of the waterway and a screen shall surround the end of the intake pipe. If possible, water shall not be withdrawn immediately after a rain event has significantly elevated the turbidity of the water supply. High suspended solids in the test water will not be justification for exceeding the TSS discharge limit.

f. If test water is discharged into an oil/water separator, settling basin or any other treatment system normally used to treat process or storm water, the rate of discharge shall not exceed the design capacity of the treatment system.

g. Discharges shall not contain visible oil sheen, floating solids or persistent foam.

3. Wastewater from draining or flushing of fire control systems

a. The permittee shall take all necessary measures to prevent erosion damage during the discharge. Any gullying greater than six inches in depth is considered excessive erosion. If the discharge is onto normally dry land or a dry drainage channel, these preventive measures may include, but are not limited to, discharge via a diffuser, discharge into riprap, discharge into a splash barrier, and flow rate controls. If the discharge is directly into flowing or standing water, preventive measures include flow rate control and locating the point of discharge in the receiving water at a sufficient depth to avoid bottom scour.



b. The discharge shall not cause the temperature of the receiving waters, beyond a mixing zone that in still water extends 50 feet radially from the outfall and in flowing water, 50 feet from the discharge point (outfall) in the direction of flow at the time of measurement to exceed 68°F in Use III or III-P receiving waters, 75°F in Use IV or IV-P receiving waters, and 90°F in Use I, I-P, or II receiving waters. If the ambient temperature of the receiving waters exceeds these standards, the temperature of the discharge shall not increase the ambient temperature of the stream.

c. For discharges over 100,000 gallons or those that equal at least half the flow in the receiving stream and which occur between May 1st and November 1st, the permittee shall verify compliance with the temperature limits identified above by measuring the temperature of the water to be discharged within a half-hour prior to discharge. If the temperature of the discharge exceeds 68°F, the permittee shall measure the temperature of the receiving waters at the edge of the mixing zone midway through the discharge period.

d. The results of monitoring in b and c, above, shall be kept with the permit registration letter, and made available to the Department upon request.

e. Per COMAR 26.08.03.06, the discharge shall not contain chlorine or chlorine-containing compounds except in nondetectable levels. The nondetectable level shall be less than 0.1 milligram/Liter as determined using either the DPD titrimetric or colorimetric method or an alternative method approved by the Department. Dechlorination may be accomplished by: i.) Chemical addition; ii.) Absorption onto activated carbon; iii.) Control of discharge rates or holding of the effluent so that chlorine residuals are

reduced to the nondetectable level; or iv.) Any other method approved in advance by the Department.

f. Discharges shall not contain visible oil sheen, floating solids or persistent foam.

4. Discharges from Potable Water Systems

This section covers all discharges from potable water utilities except any discharges from super chlorination of pipes or tanks. Super chlorinated discharges and mechanical cleaning shall meet the limits as identified in PART IV - Section B.2 - Discharges from Disinfection and Hydrostatic Testing of Pipes, Pipelines, and Tanks.

a. The permittee is authorized to discharge water from the overflow, draining, or dewatering of reservoirs, vessels or structures used to store or convey potable water for consumption including standing water, and water from flushing, hydrostatic testing, mechanical cleaning, water main breaks, leaks, or other releases.

b. All facilities shall develop a Pollution Prevention Plan (PPP) with technology based best management practices. The PPP is subject to the review and approval of the Department, upon request. For new permittees, the PPP shall address an inventory of planned discharges and their quality and necessary treatment, and shall be implemented within six months of registration under the permit. For facilities renewing permit coverage, the plan shall be reviewed and updated prior to application for permit coverage, and as necessary. i.) The PPP shall include:

1. An inventory of anticipated discharges, including type of discharge (from flushing, line maintenance, tank cleaning, etc.), and any scheduled events.

2. The expected quantity, quality, and location of each discharge.



3. All potential discharge alternatives including disposal into the sanitary sewer, overland flow, storm sewer, or other potential alternatives.

4. Any available data on the quality of previous discharges of different types, at the point where it leaves the system and at the point of entry into state waters.

5. All treatment options available for different discharge types and in different locations. 6. Stream designations and other factors used to determine the impact of the discharge

upon waters of the state. ii.) Water quality data from previous discharges and location and volume of anticipated

discharges shall be considered in developing the most protective treatment methods. iii.) The Department may notify the permittee at any time that the PPP does not meet one or

more of the minimum requirements of this PART. After such notification from the Department, the permittee shall make changes to the PPP to correct the deficiencies and shall submit to the Department a written certification that the requested changes have been made. The permittee shall have 90 days after such notification to make the necessary changes in the PPP and shall implement the changes as agreed between the permittee and the Department.

iv.) The PPP shall address practices to ensure the discharge intends to meet the conditions associated with COMAR 26.08.03.06.

c. The discharge shall not cause the temperature of the receiving waters, beyond a mixing zone that in still water extends 50 feet radially from the outfall and in flowing water, 50 feet from the outfall in the direction of flow at the time of measurement, to exceed 68°F in Use III or III-P receiving waters, 75°F in Use IV or IV-P receiving waters, and 90°F in Use I, I-P, or II receiving waters. If the ambient temperature of the receiving waters exceeds these standards, the temperature of the discharge shall not exceed (to the nearest degree F) the ambient temperature of the stream.

d. For discharges over 100,000 gallons or those that equal at least half the flow in the receiving stream and which occur between May 1st and November 1st, the permittee shall verify compliance with the temperature limits identified above by measuring the temperature of the water to be discharged within a half-hour prior to discharge. If the temperature of the discharge exceeds 68°F, the permittee shall measure the temperature of the receiving waters at the edge of the mixing zone midway through the discharge period.

e. The results of monitoring in c and d, above, shall be kept with the permit registration letter, and made available to the Department upon request.

f. The permittee shall take all necessary measures to prevent erosion damage during the discharge. Any gullying greater than six inches in depth is considered excessive erosion. If the discharge is onto normally dry land or a dry drainage channel, these preventive measures may include, but are not limited to, discharge via a diffuser, discharge into riprap, discharge into a splash barrier, and flow rate controls. If the discharge is directly into flowing or standing water, preventive measures include flow rate control and locating the point of discharge in the receiving water at a sufficient depth to avoid bottom scour.

5. Untreated “water” in excess of 10,000 gallons per day as a monthly average from water storage or distribution systems, including but not limited to hydrogeologic/aquifer/well head yield-testing

a. The permittee is authorized to discharge water from the overflow, draining, yield-testing or dewatering of reservoirs, drinking source wells and aquifers if they contain only untreated “water”.



b. The permittee shall take all necessary measures to prevent erosion damage during the discharge. Any gullying greater than six inches in depth is considered excessive erosion. If the discharge is onto normally dry land or a dry drainage channel, these preventive measures may include, but are not limited to, discharge via a diffuser, discharge into riprap, discharge into a splash barrier, and flow rate controls. If the discharge is directly into flowing or standing water, preventive measures include flow rate control and locating the point of discharge in the receiving water at a sufficient depth to avoid bottom scour.

c. At any time after authorization under this permit, the Department may determine that the permittee’s “water” discharge may cause, have reasonable potential to cause, or contribute to an excursion above any applicable water quality standard. If such a determination is made, the Department may require the permittee to: i.) Modify any current controls to adequately address, achieve and document the identified

water quality concerns; ii.) Submit valid and verifiable data and information that are representative of ambient

conditions and indicate that the receiving water is attaining water quality standards; and/or

iii.) Cease discharges from the activity and submit an individual permit application according to PART I - Section E.

6. Storm Water Discharges from Aboveground Petroleum Storage Tank Containment Structures

a. The permittee is authorized to discharge storm water from within dikes, berms, walls or any other containment structure for aboveground petroleum storage sites with a storage capacity of 10,000 gallons or more, and shall meet the limitations specified below at the final discharge point.
