NMOCD PIT RULE

19.15.17 NMACEffective June 28, 2013

Slide2

NMOCD Pit Rule

Case No. 14784 and 14785Order No. R-13506-DThis rule covers

all pits

, closed-loop systems, below-grade tanks and sumps

. Facilities under WQCC Discharge Plans are not exempt.

Slide3

NMOCD Pit Rule

Major Changes 2009 – 2013Below-grade tank now defined as > 5 bbl. CapacityContinuously flowing watercourse defined

Floodplain defined

New concept: “Life-form ratio” (re-vegetation)

Slide4

More Changes

2009 – 2013New concept: “Low chloride fluids

“Measurable” now

defined

New concept: “Multi-well fluid management pit

Definition of “significant watercourse” expanded and made more

descriptive

Temporary pits may now be used for multiple wells

Slide5

Still More Changes

Major Changes 2009 – 2013Permit still required for pits, but below-grade tanks are “registered” (district office)

Closed-loop systems require only notification of their use (district office)

Other than site-specific data may now be used to determine groundwater depth (modeling, cathodic well lithology)

Slide6

Major Changes in the Pit Rule

Major Changes 2009 – 2013Time limits for action on a permit now imposed on the NMOCD

If using “low-chloride fluids” (<15,000 mg/L):

A pit is now allowed where groundwater is at least 25 feet below the bottom of the pit

Significant changes in setbacks

Below-grade tanks meeting standards now allowed where groundwater is at least 25 feet deep

Slide7

Even More Major Changes

Major Changes 2009 – 2013A temporary pit (on-lease) or burial trench (on lease) may receive waste from another temporary pit (on-lease)

Soil beneath a BGT or drying pad shall be remediated to 600 mg/kg chlorides

Containments of only untreated fresh water are not temporary pits for the purposes of the rule

Slide8

All pits and below-grade tanks

Sumps, closed loop systemsGENERAL REQUIREMENTS

Slide9

NMOCD Pit Rule

19.15.17.9 Permit Application and RegistrationForm C-144 is to be used to apply to the division for a permit to construct or use a pit or to register a below-grade tank

May be filed by itself or included as an attachment to a permit application for the facility where the pit or below-grade tank will be located

Slide10

NMOCD Pit Rule

Pit construction requires a permit issued by the division. All pits must be lined.The division may issue a single permit for all pits associated with a single APD.

Below-grade tanks installed after June 28, 2013 must be

registered

with the appropriate division office.

Closed-loop systems and sumps do not require a permit or registration, but the district office must be notified on the APD or C-103, or applicable BLM form of use of a closed-loop system.

Slide11

NMOCD Pit Rule

Siting Requirements for Excavated MaterialNewly-excavated (non-contaminated)Distance from a continuously flowing, or significant watercourse 100 feet or greater

Pits must be fenced to deter unauthorized access

Chain link (6 feet high) with barbed wire (2 strands) on top if pit located within 1,000 feet of an occupied permanent residence, school, hospital, institution or church

Permanent pits, MWFM pits, and open top tanks must be netted

Slide13

the operator has

transferred the

wastes and the liner to a burial trench or another temporary pit, a 5-point composite sample must be taken under the

original temporary pit

Sample must be analyzed for the constituents shown in Table I of 19.15.17.13 NMAC

Additional delineation may be required by the district office if levels are exceeded

Chloride level for the soil beneath a BGT or drying pad shall be less than 600 mg/kg per EPA method 300.0

Chloride level for the soil cover for burial in place or trench burial shall be at least

4 feet

of uncontaminated soil with chloride concentration less than 600 mg/kg per EPA method 300.0

Soil covers shall be contoured to prevent erosion

Slide64

Reclamation and Re-vegetation

Re-seed in the first favorable growing season

Reclamation complete when life-form ratio of 50%, and total plant cover of 70% of pre-disturbance levels is achieved excluding noxious weeds

These requirements shall be superseded by other federal or tribal agencies if those requirements equal or exceed those specified in this rule

Slide65

EXCEPTION HANDLED BY SANTA FE

VARIANCE HANDLED BY DISTRICT OFFICEEXCEPTIONS & VARIANCES

Slide66

NMOCD Pit Rule

19.15.17.15 Exceptions and Variances“Exception” means authorization from the division’s Santa Fe office to depart from the requirements of 19.15.17 NMAC

.

Variance

” means authorization from the appropriate division district office to depart from the requirements of 19.15.17 NMAC. A variance may not be obtained where exceptions are required

specifically by

a provision of 19.15.17 NMAC.

Slide67

NMOCD Pit Rule

Exceptions and VariancesThe Commission made a conscious effort to specify, in the rule, whether a particular departure from the rule was an exception or a variance

Generally

: Any departure from a requirement concerning permanent pits must be approved by the Santa Fe office

Generally

: Any departure from any other requirement can be approved by the appropriate OCD district office

Slide68

NMOCD Pit Rule

Exceptions and VariancesIn the few instances where the rule does not specify, it is safe to assume that a departure is a variance, and can be handled by the district office

The district office may deem such a departure to be significant enough that it requires an exception

Specific procedures listed in rule to apply for exception or variance

Slide69

NMOCD Pit Rule

19.15.17.16 Permit Approvals, Conditions, Denials, Revocations, Suspensions, Modifications or TransfersDivision shall determine an application administratively complete or provide written notice as to deficiencies within 30 days of receipt

If no written notice is received, operator may assume application is administratively complete. This does not mean the permit is approved.

Slide70

NMOCD Pit Rule

19.15.17.16 Permit Approvals, Conditions, Denials, Revocations, Suspensions, Modifications or TransfersThe division has a total of 60 days to approve, deny or approve with conditions the application

If no action is taken by the division within 60 days, application is deemed denied

Operator may apply for a hearing

Slide71

NMOCD Pit Rule

19.15.17.16 Permit Approvals, Conditions, Denials, Revocations, Suspensions, Modifications or TransfersThe division may impose conditions for approvalThe division must notify the operator in writing if application is denied

The operator may

apply for a modification of a

permit

Slide72

NMOCD Pit Rule

19.15.17.16 Permit Approvals, Conditions, Denials, Revocations, Suspensions, Modifications or TransfersThe division may revoke, suspend or impose additional conditions upon discovery that the operator is in material breach of any applicable statutes or rules

Operator to be notified by certified mail, return receipt requested of any intended revocation, suspension or imposition of additional conditions

Operator may request a hearing on this matter within 10 days after receipt of such notification

Slide73

NMOCD Pit Rule

19.15.17.16 Permit Approvals, Conditions, Denials, Revocations, Suspensions, Modifications or TransfersPermits shall not be transferred without division approval
