WS 06d: Pre-Closure of a Previously Registered UIC Well

Use this form to notify MassDEP if you intend to close a UIC Class V well with an existing UIC Registration Number.

310 CMR 27.00 Contact Information


The Details

What you need

You must use this form if you propose to close a Class V well(s), but only if the well was previously registered with MassDEP. Any Class V well (including unauthorized wells, such as motor-vehicle-waste disposal wells) that was not previously registered with MassDEP must instead use the applicable UIC Registration Form (BRP WS 06). The only types of Class V wells that do not require UIC Registration are:

  • wells that have a permit from the MassDEP Groundwater Discharge Program (314 CMR 5.00)
  • sewage treatment and disposal systems regulated under Title 5 (310 CMR 15.00)
  • UIC Class V wells that did not require UIC registration because the property is only used for single-family residential use.

Note that even if the original well use was exempt from registration, all abandoned wells (wells that were not properly closed before they came into a state of disrepair) require UIC Registration and Closure.

If you are submitting pre-closures for multiple UIC registrations, you must use a separate form for each unique registration number.

This application form applies to all land uses.

Regulations that apply primarily include, but are not limited to:  Underground Injection Control Program, 310 CMR 27.00.

The closure of UIC Class V wells must comply with the Mass DEP Guidance Document #: BRP/DWM/DW/G04-3,Massachusetts Closure Guidance for Underground Injection Control (UIC) Wells (including shallow injection wells)   Please note that although this document applies to all UIC Class V well closures, it focuses on the closure of motor vehicle-waste disposal wells. Therefore, the sampling requirements listed in those guidelines do not necessarily apply to nonmotor vehicle-waste disposal wells. Sampling requirements for other types of wells depend upon the nature of the discharge and whether any known or suspected contaminants entering the well may have resulted in a reportable release of oil and/or hazardous materials per the Massachusetts Contingency Plan (MCP) 310 CMR 40.0000 .

If your application is for the conversion of a well to a different well type then you must also submit the applicable BRP WS06 Registration application (with a separate payment transmittal form) and pay the fee associated with that registration application.

In addition to the above UIC registration requirements, applicants should consider the need to obtain the following permits or sanctions:

  • Wetlands requirements should be checked through the local Conservation Commission.

  • Local Board of Health requirements may also apply.

  • Local Plumbing Inspector requirements may also apply.

Note: The additional requirements listed above are examples intended to serve as a guide to the applicant. They do not necessarily include all possible additional requirements.

You should only file electronically using eDEP if either of the following is true:

  1. The original UIC Registration application was submitted electronically through eDEP and not through a paper filing; or,
  2. A subsequent Modification UIC Registration application was submitted electronically through eDEP in which the well locations of the previously registered UIC Class V wells were entered.

Otherwise you should file for Pre-Closure using the paper version of the form.

How to apply

See details in Step 5, below.

Next steps

  1. Review the Instructions

    If your original UIC registration was filed electronically via eDEP, use the first set of instructions.

    If your original UIC registration was filed via paper, use the second set of instructions.

  2. Complete the Application Form

    eDEP Online Filing

    If your original UIC registration was filed via paper, you cannot use eDEP to file your UIC pre-closure application but must submit a paper copy.  You may fill out and save the Microsoft Word form on your computer. The PDF version has to be printed out and completed by hand. 

  3. Obtain a Transmittal Form and Number

    If you are not submitting your registration via eDEP, use this link to obtain a unique Transmittal Number for each application you submit to MassDEP. 

  4. Look up the Permit Application Fee

    See page 7 of the fee schedule below.

  5. Submit your Application and Fee Payment

    If not submitting via eDEP, submit your fee(s) and copy(ies) of your transmittal form(s) to:

    Department of Environmental Protection
    PO Box 4062
    Boston, MA 02211

    Submit your completed application form(s) and original transmittal form(s) to:

    Underground Injection Control Program
    One Winter Street, 5th floor
    Boston, MA 02108

    Please note that the PO box shown on the Transmittal Form for Permit Application and Payment is for the bank that MassDEP uses to deposit permit and registration fees. If you send the entire application package to the PO box rather than the One Winter Street address, the bank will discard everything other than the Payment Transmittal Form and check and you will be required to resubmit your application package to MassDEP.

  6. Timelines

    If MassDEP fails to issue a determination for the pre-closure registration of the UIC Class V well on an adequately prepared BRP WS-06 Pre-Closure application within 30 days of receipt of the application and payment of the application fee, MassDEP will refund the entire fee and will continue with the review.
