NB/6/ORD
806-11-01-22o-so-2 -23-
any confirmed or unconfirmed unauthorized discharge of a hazardous or other regulated material which is liquid or solid at normal t emperature and pressure, such person shall take all necessary steps to ensure the discovery, containment and cleanup of such discharge and shall notify the city of the occurrence as required by this subsection.

1. Confirmed unauthorized discharge.

(a) Recordable unauthorized discharge. Any recordable unauthorized discharge shall be contained and safely disposed of in an appropriate manner and such occurrence and the response thereto shall be recorded in the person ’s, firm’s or corpora tion’s monitoring records. A recordable unauthorized discharge is any unauthorized discharge of a hazardous or other regulated material which meets all of the following criteria:

i. The discharge is from a primary containment to a secondary containment or to a rigid aboveground surface covering capable of containing the discharge until cleanup of the hazardous or other regulated material is completed; and

ii. The discharge is able to be adequately cleaned up before it escapes from such secondary containment or such aboveground surface, but if the cleanup requires more than eight (8) hours, it becomes a reportable discharge in accordance with subsection

24.5.0.a.1(b) below; and

iii. There is no increase in the hazard of fire or explosion, no r is there any production of a flammable or poisonous gas, nor is there any deterioration of such secondary containment or such rigid, aboveground surface.

iv. An otherwise recordable unauthorized discharge does not need to be recorded if the dischar ge is not the result of the deterioration or failure of the primary container, the quantity discharged is less than one (1) ounce by weight and the discharge can be cleaned up within fifteen (15) minutes.

(b) Reportable unauthorized discharge. Any unauthorized discharge which is determined not to be recordable under subsection 24.5.0.a.1(a) above, must immediately be reported to city ’s fire department via the 9 -1-1 emergency number. The reporting party shall indicate the ability of the responsible part y to contain and dispose of the hazardous or other regulated material, the estimated time it will take to complete containment and disposal , and the degree of hazard created. The city may verify that the hazardous or other regulated material is being adequately contained and appropriately disposed. At any time the city determines the party performing the containment or disposal: (a) is not adequately containing or disposing of such hazardous or other regulated materials; (b) is not adequately trained to do so; (c) does not have adequate resources or supplies to do so; or (d) does not have a practical or safe containment or disposal plan, the city shall have the power and authority to undertake and direct an emergency response in order to protect the public h ealth, safety and/or welfare and the Attachment 3

environment. Costs associated with such emergency response shall be borne by the owner, operator or other person responsible for the unauthorized discharge.

Within fifteen (15) calendar days of a reportable discha rge, the responsible party shall submit a written report to the city, including:

i. A description of the incident, including actions taken by facility personnel during and immediately following the reportable discharge;

ii. A determination of the cause or causes of the reportable discharge;

iii. Administrative and engineering controls which the responsible party proposes to implement to reduce the likelihood of a reportable discharge recurring;

iv. The target date for completing implementation of such controls; and

v. The signature of a corporate officer of the responsible facility.

2. Unconfirmed unauthorized discharge.

(a) Indication of loss of inventory. Whenever a material balance, inventory record, or monitoring detection system employed as a monitoring technique under the HMBP indicates a loss of hazardous or other regulated material , and no unauthorized discharge has been confirmed by other means, the responsible party shall immediately record such discrepancy in his/her their responsible party’s monitoring records, immediately notify the fire department’s environmental safety division of the discrepancy , and determine, within five (5) business days, whether or not there has been an unauthorized discharge. If, before the end of such period, it is determined there has been no unauthorized discharge, an entry explaining the occurrence shall be made in the responsible party’s monitoring records. Where the responsible party has not been able, within such period , to determine there has been no unauthorized discharge, an unauthorized discharge is deemed confirmed , and the responsible party shall proceed in accordance with subsection 24.5.0.a.1(b) above.

(b) Test results. Whenever any test results suggest a possible unauthorized discharge, and no unauthorized discharge has been confirmed by other means, the responsible party shall immediately notify the enviro nmental safety division of the possible discharge and shall perform two (2) retests, at least twenty-four (24) hours apart, within five (5) business days.

If both retest results establish there has been no unauthorized discharge, the results of all three (3) tests shall be recorded in the responsible party ’s monitoring records. If it has not been established within such period that there has been no unauthorized discharge, an unauthorized discharge is deemed confirmed , and the responsible party shall procee d in accordance with subsection 24.5.0.a.1(b) above.
