Section 250-RICR-150-05-4.15 - Modification of a Groundwater Discharge System

A. The owner of a facility operating under a Groundwater or Stormwater Discharge System Registration, Groundwater Discharge System Approval or Temporary Approval shall obtain a modification of the Registration or Approval prior to the initiation of any addition, expansion or other modification or condition related to the groundwater discharge or the groundwater discharge system, including, but not limited to:

1. A change to the type or quality of wastewater or other fluid discharged to the groundwater discharge system;

2. A change to the quantity of wastewater or other fluid discharged to the groundwater discharge system;

3. A change to the approved groundwater discharge system piping or other devices or system of treatment and control and related appurtenances, including a change in placement location; or,

4. A minor modification as described in § 4.15(E) of this Part.

B. The Director shall also require modification of a Registration or Approval under the following conditions:

1. The identification of any information that indicates the approved groundwater discharge has caused or contributed or may cause or contribute to a violation of a primary drinking water regulation under the federal Safe Drinking Water Act or a groundwater quality standard established by the RIDEM Groundwater Quality Rules Part 3 of this Subchapter or any other State or federal law, rule, regulation or standard; or,

2. The identification of new information that was not available at the time of issuance that would have justified the application of additional or different conditions in the Registration or Approval.

C. Application Requirements: The owner shall submit to the Director an Application to Modify a Groundwater or Stormwater Discharge System, prepared in accordance with § 4.8 of this Part, and any other information required by the application or the Director.

D. If at any time, a groundwater discharge or groundwater discharge system is modified to the extent that the analytical characterization or other measurement required by a Groundwater Discharge System Approval or Temporary Approval is incorrect or insufficient, a revised set of parameters shall be established by the Director in accordance with the Approval and these rules.

E. A modification shall be considered minor in order to:

1. Correct significant or meaningful typographical errors;

2. Decrease the frequency of compliance monitoring and reporting of a groundwater discharge or groundwater quality. The Director may modify a Groundwater Discharge System Approval or Temporary Approval to decrease the frequency of monitoring and reporting only if it is determined that the discharge has not changed, the historic facility monitoring data demonstrates such consistency and the continued level of monitoring will not provide additional relevant information; or,

3. Change requirements related to construction and installation of a groundwater discharge system if the change complies with the requirements of these rules.

F. The filing, by the owner, of an Application to Modify a Groundwater or Stormwater Discharge System does not stay any condition of a Groundwater or Stormwater Discharge System Registration, Approval or Temporary Approval.
