The director shall be entitled to rely upon the waiver to approve the permit application or permit modification.

C. The director may not issue a permit to drill for gas or oil or approve a permit modification for a well where additional documentation is required pursuant to subdivision B 5 of 4VAC25-150-110 in Tidewater Virginia until he has considered the findings and recommendations of the collaborated with the Department of Environmental Quality, as provided for in § 62.1-195.1 of the Code of Virginia and, where appropriate, has required changes in the permitted activity based on to ensure permit conditions accurately reflect the results from the Department of Environmental Quality's recommendations coordinated review of the environmental impact assessment required pursuant to § 62.1-195.1 of the Code of Virginia.

D. The provisions of any order of the Virginia Gas and Oil Board that govern a gas or oil well permitted by the director shall become conditions of the permit.

4VAC25-150-280. Logs and surveys.

A. Each permittee drilling a well or corehole shall complete a driller's log, a gamma ray log, or other log showing the top and bottom points of geologic formations and any other log required under this section. The driller's log shall state, at a minimum, the character, depth, and thickness of geological formations encountered, including groundwater-bearing strata, coal seams, mineral beds, and gas-bearing or oil-bearing formations.

B. When a permittee or the director identifies that a well or corehole is to be drilled or deepened in an area of the Commonwealth which that is known to be underlain by coal seams, the following shall be required:

1. The vertical location of coal seams in the well or corehole shall be determined and shown in the driller's log and gamma ray log or other log.

2. The horizontal location of the well or corehole in coal seams shall be determined through an inclination survey from the surface to the lowest known coal seam. Each inclination survey shall be conducted as follows:

a. The first survey point shall be taken at a depth not greater than the most shallow coal seam; and

b. Thereafter shot points shall be taken at each coal seam or at intervals of 200 feet, whichever is less, to the lowest known coal seam.

3. Prior to drilling any well or corehole within 500 feet of a coal seam in which there are active workings, the permittee shall conduct an inclination survey to determine whether the deviation of the well or corehole exceeds one degree from true vertical. If the well or corehole is found to exceed one degree from vertical, then the permittee shall:

a. Immediately cease operations;

b. Immediately notify the coal owner and the division;

c. Conduct a directional survey to drilled depth to determine both horizontal and vertical location of the well or corehole; and

d. Unless granted a variance by the director, correct the well or corehole to within one degree of true vertical.

4. Except as provided for in subdivision B 3 of this section, if the deviation of the well or corehole exceeds one degree from true vertical at any point between the surface and the lowest known coal seam, then the permittee shall:

a. Correct the well or corehole to within one degree of true vertical; or

b. Conduct a directional survey to the lowest known coal seam and notify the coal owner of the actual well or corehole location.

5. The director may grant a variance to the requirements of subdivisions B 3 and B 4 of this section only after the permittee and coal owners have jointly submitted a written request for a variance stating that a directional survey or correction to the well or corehole is not needed to protect the safety of any person engaged in active coal mining or to the environment.

6. If the director finds that the lack of assurance of the horizontal location of the well or corehole to a known coal seam poses a danger to persons engaged in active coal mining or the lack of assurance poses a risk to the public safety or the environment, the director may, until 30 days after a permittee has filed the completion report required in 4VAC25-150-360, require that a directional survey be conducted by the permittee.

7. The driller's log shall be updated on a daily basis. The driller's log and results of any other required survey shall be kept at the site until drilling and casing or plugging a dry hole or corehole are completed.

C. Each permittee completing a well shall complete a cement bond log for the water protection string. [ Permittees may petition the director to submit alternative documentation that demonstrates effective bond between the casing and the formation. ]

4VAC25-150-300. Pits.

A. General requirements.

1. Pits are to be temporary in nature and are to be reclaimed when the operations using the pit are complete. All pits shall be reclaimed within 180 days unless a variance is requested and granted by the field inspector.

2. Pits may not be used as erosion and sediment control structures or stormwater management structures, and surface drainage may not be directed into a pit.

3. Pits shall have a properly installed and maintained liner or liners made of 10 mil or thicker high-density polyethylene or its equivalent.

4. Pits shall be constructed of sufficient size and shape to contain all fluids and maintain a two-foot freeboard.

5. Pits shall be enclosed by adequate fencing to secure the site from access by the public and wildlife.

Upon failure of the lining or pit, the operation shall be shut down until the liner and pit are repaired or rebuilt. The permittee shall notify the division, by the quickest available means, of any pit leak.

2. Motor oil and, to the extent practicable, crude oil shall be kept out of the pit. Oil shall be collected and disposed of properly. Litter and other solid waste shall be collected and disposed of properly and not thrown into the pit.

3. At the conclusion of drilling and completion operations or after a dry hole, well, or corehole has been plugged, the pit shall be drained in a controlled manner and the fluids disposed of in accordance with 4VAC25-150-420. If the pit is to be used for disposal of solids, then the standards of 4VAC25-150-430 shall be met.

4VAC25-150-340. Drilling fluids.

A. Operations plan requirements. Applicants for a permit shall provide, prior to commencing drilling, documentation that the water meets the requirements of subsection B of this section, and a general description of the additives and muds to be used in all stages of drilling. Providing that the requirement in 4VAC25-150-340 subsection C of this section is met, variations necessary because of field conditions may be made with prior approval of the director and shall be documented in the driller's log.

B. Water quality in drilling.

1. Before the water-protection string is set, permittees shall use one of the following sources of water in drilling:

a. Water that is from a water well or spring located on the drilling site; or

b. Conduct an analysis of groundwater within 500 feet a one-quarter-mile radius of the drilling location, and use:

(1) Water which is of equal or better quality than the groundwater; or

(2) Water which can be treated to be of equal or better quality than the groundwater. A treatment plan must be included with the application if water is to be treated.

(3) If, after a diligent search, a groundwater source (such as a well or spring) cannot be found within 500 feet a one-quarter-mile radius of the drilling location, the applicant may use water meeting the parameters listed in the Department of Environmental Quality's "Ground water criteria," 9VAC25-280-70. The analysis shall include, but is not limited to, the following items:

(1) (a) Chlorides;

(2) (b) Total dissolved solids;

(4) Drilling water analysis shall be taken within a one-year period preceding the drilling application.

2. After the water-protection string is set, permittees may use waters that do not meet the standards of subdivision B 1 of this section.

C. Drilling muds. No permittee may use an oil-based drilling fluid or other fluid which has the potential to cause acute or chronic adverse health effects on living organisms unless a variance has been approved by the director. Permittees must explain the need to use such materials and provide the material data safety sheets. In reviewing the request for the variance, the director shall consider the concentration of the material, the measures to be taken to control the risks, and the need to use the material. Permittees shall also identify what actions will be taken to ensure use of the additives will not cause a lessening of groundwater quality.

4VAC25-150-360. Drilling, completion, and other reports.

A. Each permittee conducting drilling shall file, electronically or on a form prescribed by the director, a drilling report within 90 days after a well reaches total depth.

B. Each permittee drilling a well shall file, electronically or on a form prescribed by the director, a completion report within 90 days after the well is completed. All completion reports shall include the cement bond log required in subsection C of 4VAC25-150-280. Subject to the approval of the director, permittees may submit alternative documentation that demonstrates effective bond between the casing and the formation.

C. The permittee shall file the driller's log, the results of any other log or survey required to be run in accordance with this chapter or by the director, and the plat showing the actual location of the well with the drilling report, unless they have been filed earlier.

D. The permittee shall, within 90 days of reaching total depth, file with the division the results of any gamma ray, density, neutron and, induction, and cement bond logs, or their equivalent, that have been conducted on the wellbore in the normal course of activities that have not previously been required to be filed.

4VAC25-150-365. Disclosure of well stimulation fluids.

A. In addition to other requirements that may be prescribed by the director, each completion report required in 4VAC25-150-360 shall also contain the following disclosures:

The operator of the well shall complete the Chemical Disclosure Registry form and upload the form on the Chemical Disclosure Registry, including:

i. Each additive used in the hydraulic fracturing treatments and the trade name, supplier, and a brief description of the intended use or function of each additive in the hydraulic fracturing treatment or treatments;

j. Each chemical ingredient used in the hydraulic fracturing treatment or treatments of the well that is subject to the requirements of 29 CFR 1910.1200(g)(2), as provided by the chemical supplier or service company or by the operator, if the operator provides its own chemical ingredients;

k. The actual or maximum concentration of each chemical ingredient listed under subdivision j of this subsection in percent by mass;

l. The CAS number for each chemical ingredient listed, if applicable; and

m. A supplemental list of all chemicals, their respective CAS numbers, and the proportions thereof not subject to the requirements of 29 CFR 1910.1200(g)(2), that were intentionally included in and used for the purpose of creating the hydraulic fracturing treatments for the well.

B. [ The department shall obtain and maintain data submitted to the Chemical Disclosure Registry. ] If the Chemical Disclosure Registry is temporarily inoperable, the operator of a well on which hydraulic fracturing treatment or treatments were performed shall supply the department with the required information and upload the information on the registry when it is again operable. The information required shall also be filed as an attachment to the completion report for the well, which shall be posted, along with all attachments, on the department's website, except that information determined to be subject to trade secret protection shall not be posted.

C. All information related to the specific identity or CAS number or amount of any additive or chemical ingredient used in hydraulic fracturing shall be submitted to the department and shall be available to the public unless the department determines that information supplied by the operator and claimed to be a trade secret is entitled to such protection. All information claimed as a trade secret shall be identified as such at the time of submission of the appropriate report. The department shall treat as confidential in accordance with law, information that meets the criteria specified in law for a trade secret and is contained on such forms and filings as is required under this chapter. [ Such criteria shall include a demonstration by the claimant that the information derives independent economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use, and is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. ]

Should the department determine that information is protected as a trade secret, the operator of the well shall indicate on the Chemical Disclosure Registry or the supplemental list that the additive or chemical ingredient or their amounts are entitled to trade secret protection. If a chemical ingredient name or CAS number is entitled to trade secret protection, the chemical family or other similar description associated with such chemical ingredient shall be provided. The operator of the well on which hydraulic fracturing was performed shall provide the contact information, including the name, authorized representative, mailing address, and phone number of the business organization for which trade secret protection exists. Unless the information is entitled to protection as a trade secret, information submitted to the department or uploaded on the Chemical Disclosure Registry is public information.

D. The operator understands that the director may disclose information regarding the specific identity of a chemical, the concentration of a chemical, or both the specific identity and concentration of a chemical claimed to be a trade secret to additional department staff to the extent that such disclosure is necessary to assist the department in responding to an emergency resulting in an order pursuant to subsection D of § 45.1-361.27 of the Code of Virginia provided that such individuals shall not disseminate the information further. In addition, the director may disclose such information to any relevant state or local government official to assist in responding to the emergency. Any information so disclosed shall at all times be considered confidential and shall not be construed as publicly available. [ The director shall notify the trade secret claimant or holder of disclosures made to relevant state or local government officials as soon as practicable after such disclosure is made. ]

E. An operator may not withhold information related to chemical ingredients used in hydraulic fracturing, including information identified as a trade secret, from any health professional or emergency responder who needs the information for diagnostic, treatment, or other emergency response purposes subject to procedures set forth in 29 CFR 1910.1200(i). An operator shall provide directly to a health professional or emergency responder, all information in the person's possession that is required by the health professional or emergency responder, whether or not the information may qualify for trade secret protection under this section. The person disclosing information to a health professional or emergency responder shall include with the disclosure, as soon as circumstances permit, a statement of the health professional's confidentiality obligation. In an emergency situation, the operator shall provide the information immediately upon request to the person who determines that the information is necessary for emergency response or treatment. The disclosures required by this subsection shall be made in accordance with the procedures in 29 CFR 1910 with respect to a written statement of need and confidentiality agreements, as applicable.

4VAC25-150-535. Pressure testing requirements for production casing in conventional gas or oil wells.

A. The operator shall install casing that can withstand the effects of tension and can prevent leaks, burst, and collapse during (i) the casing's installation and cementing and (ii) subsequent drilling and producing operations.

B. Except as provided in subsection C of this section, all casing must be a string of new pipe with an internal pressure rating that is at least 20% greater than the anticipated maximum pressure to which the casing will be exposed.

C. Used casing may be approved for use as surface, intermediate, or production casing but shall be pressure tested after cementing and before completion. A passing pressure test is holding the anticipated maximum pressure to which it will be exposed for 30 minutes with not more than a 10% decrease in pressure.

D. New or used plain end casing, except when being used as conductor pipe, that is welded together for use must meet the following requirements:

1. The casing must pass a pressure test by holding the anticipated maximum pressure to which the casing will be exposed for 30 minutes with not more than a 10% decrease in pressure. The operator shall notify the department [ electronically ] at least 24 hours before conducting the test. The test results shall be entered on the drilling report.

2. The casing shall be welded using at least three passes with the joint cleaned between each pass.

4VAC25-150-610. Casing requirements for coalbed methane gas wells.

A. Water protection string.

1. Except as provided in subdivision A 5 of this section, the permittee shall set a water-protection string set to a point at least 300 feet below the surface or 50 feet below the deepest known groundwater horizon, whichever is deeper, circulated and cemented to the surface. If cement does not return to the surface, every reasonable effort shall be made to fill the annular space by introducing cement from the surface.

2. The operator shall test or require the cementing company to test the cement mixing water for pH and temperature prior to mixing the cement and to record the results on the cementing ticket.

3. After the cement is placed, the operator shall wait a minimum of eight hours and allow the cement to achieve a calculated compressive strength of 500 psi before drilling, unless the director approves a shorter period of time. The wait-on-cement (WOC) time shall be recorded within the records kept at the drilling rig while drilling is taking place.

4. When requested by the director, the operator shall submit copies of cement tickets or other documents that indicate the above specifications have been followed.

5. A coal-protection string may also serve as a water protection string only for gob wells.

B. Coal protection strings.

1. When any well penetrates coal seams that have not been mined out, the permittee shall, except as provided in subdivisions B 2 and B 3 of this section, set a coal-protection string. The coal-protection string shall exclude all fluids, oil, gas, and gas pressure, except that which is naturally present in each coal seam. The coal-protection string shall also exclude all injected material or disposed waste from the coal seams or the wellbore. The string of casing shall be set to a point at least 50 feet below the lowest coal seam, or as provided in subdivision B 3 of this section, and shall be circulated and cemented from that point to the surface, or to a point not less than 50 feet into the water-protection string or strings which are cemented to the surface.

2. For good cause shown, either before or after the permit is issued, when the procedure specified in subdivision B 1 of this section is demonstrated by the permittee as not practical, the director may approve a casing program involving:

a. The cementing of a coal-protection string in multiple stages;

b. The cementing of two or more coal-protection strings; or

c. The use of other alternative casing procedures.

3. The director may approve the program, provided he is satisfied that the result will be operationally equivalent to compliance with the provisions of subdivision B 1 of this section for the purpose of permitting the subsequent safe mining through the well or otherwise protecting the coal seams as required by this section. In the use of multiple coal-protection strings, each string below the topmost string shall be cemented at least 50 feet into the next higher string or strings that are cemented to the surface and be verified by a cement top log.

4. Depth of coal-protection strings.

a. A coal-protection string shall be set to the top of the red shales in any area underlain by them unless, on a showing by the permittee in the permit application, the director has approved the casing point of the coal-protection string at some depth less than the top of the red shales. In such event, the permittee shall conduct a gamma-ray/density log survey on an expanded scale to verify whether the well penetrates any coal seam in the uncased interval between the bottom of the coal-protection string as approved and the top of the red shales.

b. If an unanticipated coal seam or seams are discovered in the uncased interval, the permittee shall report the discovery in writing to the director. The permittee shall cement the next string of casing, whether a part of the intermediate string or the production string, in the applicable manner provided in this section for coal-protection strings, from a point at least 50 feet below the lowest coal seam so discovered to a point at least 50 feet above the highest coal seam so discovered.

c. The gamma-ray/density log survey shall be filed with the director at the same time the driller's log is filed under 4VAC25-150-360.

d. When the director believes, after reviewing documentation submitted by the permittee, that the total drilling in any particular area has verified the deepest coal seam higher than the red shales, so that further gamma-ray/density logs on an expanded scale are superfluous for the area, he may waive the constructing of a coal-protection string or the conducting of such surveys deeper than 100 feet below the verified depth of the deepest coal seam.

C. Coal-protection strings of wells drilled prior to July 1, 1982. In the case of wells drilled prior to July 1, 1982, through coal seams without coal-protection strings as prescribed in subsection B of this section, the permittee shall retain such coal-protection strings as were set. During the life of the well, the permittee shall, consistent with a plan approved by the director, keep the annular spaces between the various strings of casing adjacent to coal seams open to the extent possible, and the top ends of all such strings shall be provided with casing heads, or such other approved devices as will permit the free passage of gas or oil and prevent filling of the annular spaces with dirt or debris.

D. Producing from more than one stratum. The casing program for any well designed or completed to produce from more than one stratum shall be designed in accordance with the appropriate standard practices of the industry.

E. Casing through voids.

1. When a well is drilled through a void, the hole shall be drilled at least 30 feet below the void. The annular space shall be cemented from the base of the casing up to the void, and every reasonable attempt shall be made to fill up the annular space from the top of the void to the surface; or it shall be cemented at least 50 feet into the next higher string or strings of casing that are cemented to the surface, and shall be verified by a cement top log.

2. For good cause shown, the director may approve alternate casing procedures proposed by the permittee, provided that the director is satisfied that the alternative casing procedures are operationally equivalent to the requirements imposed by subdivision E 1 of this section.

3. For good cause shown, the director may impose special requirements on the permittee to prevent communication between two or more voids.

F. A well penetrating a mine other than a coal mine. In the event that a permittee has requested to drill a well in such a location that it would penetrate any active mine other than a coal mine, the director shall approve the safety precautions to be followed by the permittee prior to the commencement of activity.

G. Production casing.

1. Unless otherwise granted in a variance from the director:

a. For coalbed methane gas wells with cased completions and cased/open hole completions, production casing shall be set and cemented from the bottom of the casing to the surface or to a point not less than 50 feet into the lowest coal-protection or water-protection string or strings which are cemented to the surface.

b. For coalbed methane gas wells with open hole completions, the base of the casing shall be set to not more than 100 feet above the uppermost coalbed which is to be completed open hole. The casing shall be cemented from the bottom of the casing to the surface or to a point not less than 50 feet into the lowest coal-protection or water-protection string or strings which are cemented to the surface.

2. A coal-protection string may also serve as production casing.

H. Reporting of lost circulation zones. The permittee shall report to the director as soon as possible when an unanticipated void or groundwater horizon is encountered that results in lost circulation during drilling. The permittee shall take every necessary action to protect the lost circulation zone.

4VAC25-150-615. Pressure testing requirements for production casing in coalbed methane gas wells.

A. The operator shall install casing that can withstand the effects of tension and can prevent leaks, burst, and collapse during (i) the casing's installation and cementing and (ii) subsequent drilling and producing operations.

B. Except as provided in subsection C of this section, all casing must be a string of new pipe with an internal pressure rating that is at least 20% greater than the anticipated maximum pressure to which the casing will be exposed.

C. Used casing may be approved for use as surface, intermediate, or production casing but shall be pressure tested after cementing and before completion. A passing pressure test is holding the anticipated maximum pressure to which it will be exposed for 30 minutes with not more than a 10% decrease in pressure.

D. New or used plain end casing, except when being used as conductor pipe, that is welded together for use must meet the following requirements:

1. The casing must pass a pressure test by holding the anticipated maximum pressure to which the casing will be exposed for 30 minutes with not more than a 10% decrease in pressure. The operator shall notify the department [ electronically ] at least 24 hours before conducting the test. The test results shall be entered on the drilling report.

2. The casing shall be welded using at least three passes with the joint cleaned between each pass.

E. The provisions of this section shall not apply to gob wells.
