N.H. Admin. Code § Env-Wq 1504.08

Current through Register No. 44, October 31, 2024

Section Env-Wq 1504.08 - Source Control Plans

(a) A source control plan required by Env-Wq 1503.11(f) shall be designed to:

(1) Minimize the volume of stormwater and runoff that can contact regulated substances; and

(2) Segregate relatively clean stormwater and runoff from stormwater and runoff that has a higher concentration of pollutants.

(b) The owner of a site from which stormwater will discharge that requires an NPDES permit as defined under 40 CFR 122.26 may submit a stormwater pollution prevention plan (SWPPP) to meet the requirements of this section for a source control plan if such SWPPP also identifies:

(1) The location(s) of groundwater protection areas, if any, within 1,000 feet of the site perimeter; and

(2) Procedures and practices to protect groundwater quality.

(c) The source control plan may exclude the items described in (e)(2) through (e)(10), below, if the plan demonstrates that the site is designed in a manner that will prevent the exposure of regulated substances to precipitation or runoff, taking into account the possibility of accidental spills.

(d) The source control plan may exclude the items described in (e)(3) through (e)(10), below, if the plan covers only a commercial parking lot where the only regulated substance exposed to rainfall or runoff is road salt that has been applied for deicing of pavement on the site, provided that snow and ice management will be done by a commercial applicator certified under Env-Wq 2200.

(e) A source control plan shall consist of:

(1) An overview of how source controls, including structural or operational management practices, will prevent or minimize the amount of regulated substances from mixing with clean stormwater;

(2) A plan showing the location(s) of snow storage areas;

(3) A list of regulated substances expected to be present on the site in quantities of 5 gallons or more;

(4) The location(s) of groundwater protection areas, if any, within 1,000 feet of the site perimeter;

(5) A plan depicting the drainage area with exposed regulated substances and the location(s) of stormwater management systems or discharge point(s) serving those areas, including latitude-longitude point(s) of the practice or discharge point(s) to within plus or minus 5 meters of the practice or discharge point;

(6) The location(s) and containment method(s) to be employed for storage of regulated substances;

(7) A plan depicting the location(s) where regulated substances will be handled, including the storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, finished product, by-product, or waste product;

(8) A description of spill prevention and control or containment measures;

(9) A list of the phone numbers and mailing addresses of the owner of the facility; and

(10) A program of training to familiarize employees with the plan and to ensure its implementation.

(f) The owner of a site for which a source control plan is required shall:

(1) Update the source control plan as necessary to reflect changes in the storage of regulated substances;

(2) Submit the updated source control plan to the department whenever it is updated; and

(3) Certify once every 3 years that the site is in compliance with its permit with respect to the implementation of its source control plan, by submitting to the department a completed and signed Source Control Plan Certification Form dated 2017.

(g) The owner shall provide the following information and certifications on the Source Control Plan Certification Form required by (f), above:

(1) The AOT permit number;

(2) The town or city in which the project is located;

(3) The name and title of the individual who has been authorized to sign the form on behalf of the owner;

(4) The mailing address, telephone number including area code, and email address of the authorized individual;

(5) The date of the plans that were originally approved as part of the AOT permit and the date of the most recent amendment of such plans, if any;

(6) The date of the originally-approved source control plan and the date of the most recent revision of such plan, if any;

(7) As applicable, certification that:

a.No changes have occurred in the storage, handling, or use of regulated substance or to the structural or non-structural controls as described in the most recently-approved source control plan;

b.Activities that expose regulated substances to precipitation or runoff that were not identified in the most recently-approved source control plan are now occurring, and:

1.An updated source control plan was submitted to the department, with the date of such submission; or

2.An updated source control plan is attached to the certification; or

c.There are no longer any activities on the property that expose regulated substances to precipitation or runoff and so a source control plan is no longer required; and

(8) Certification that:

a.The information provided on or otherwise submitted with the certification form is true, complete, and not misleading to the knowledge and belief of the signer; and

b.The signer understands that if the information is untrue, incomplete, or misleading, the signer is subject to the penalties specified in New Hampshire law for falsification in official matters, currently RSA 641.
