The following words, terms and phrases, when used in this chapter, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

Best management practices (BMPs) means the specific management practices used to control pollutants in storm water. BMPs are of two types: “source controls” (nonstructural) and “treatment controls” (structural). Source or nonstructural controls are practices that prevent pollution by reducing potential pollutants at their source, such as proper chemical containment at municipal shops or construction sites, before they come into contact with storm water. Treatment or structural controls, such as constructed water quality detention facilities, remove pollutants already present in storm water. Best management practices can either be temporary, such as silt fence used during construction activity, or permanent detention facilities, to control pollutants in storm water.

(d)    Upset Condition.

(1)    An upset condition determination constitutes an affirmative defense to an action brought for noncompliance when the terms of this chapter are met. An owner who wishes to establish the affirmative defense of upset must demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

(i)    An upset occurred and that the cause(s) of the upset can be identified; and

(ii)    The facility or operation was at the time being properly operated; and

(iii)    Notice of the upset was submitted as required in GJMC 13.28.020(d); and

(iv)    Remedial measures were complied with as required.

(2)    Burden of Proof. In any enforcement proceeding, the one seeking to establish the occurrence of an upset has the burden of proof.

(e)    Any person wishing to appeal any decision, action, administrative order, assessment of administrative fine, or determination made and issued by the City Manager in interpreting, enforcing or implementing the provisions of this chapter, or the provision of any administrative order issued under this chapter, shall file with the City Manager a written request for reconsideration within 10 working days of such decision, action, administrative order or determination. That written request shall set forth in detail the facts supporting the request. The City Manager shall hold a hearing within 10 working days of such request. All requests for reconsideration shall be heard by the City Manager within 10 working days from the date of the hearing. The decision, action, administrative order or determination shall remain in effect during the reconsideration period.

(f)    Any person entitled to appeal an order of the City Manager pertaining to a violation of this chapter may do so by filing an appeal with the City Manager within 10 working days from the date of the City Manager’s determination or order. The appeal shall contain the following items:

(1)    A heading in the words “Before the Storm Water Hearing Board of the City of Grand Junction, Colorado” or “Before the Storm Water Hearing Officer of the City of Grand Junction, Colorado”;

(2)    A caption reading “Appeal of ________,” giving the names of all participating appellants;

(3)    A statement of the legal interest of the appellants in the affected facility, together with the name of the authorized representative thereof;

(4)    A concise statement of the action protested, together with any material facts;

(5)    Verified signatures of all appellants, together with official mailing addresses and telephone numbers; and

(6)    Verification by declaration under perjury of at least one appellant as to the truth of the matters stated in the appeal.

Upon receipt of a properly filed appeal, the City Manager shall notify the City Council, and the City Manager shall convene a Storm Water Hearing Board or appoint a Hearing Officer. The hearing shall commence no sooner than 10 days, but no later than 60 days, after the appeal is filed.

(g)    The City Manager is authorized to order any user who causes, makes, or allows an unauthorized direct or indirect discharge or a harmful contribution to the storm drainage system to show cause why appropriate enforcement action should not be taken. In such case, a notice shall be served on the respondent user specifying the time and place of a hearing regarding the violation, the reasons why the action is to be taken, the proposed enforcement action, and directing the user to show cause why the proposed enforcement action should not be taken. The notice of the hearing shall be served upon the user personally or by certified mail, return receipt requested, at least 10 days before the hearing. Service may be made on any agent or authorized representative of a corporation or partnership.

(h)    The City Manager may appoint a Hearing Officer or may instead convene a Storm Water Hearing Board to conduct the hearing or appeal. The Board may consist of a City Council member or designee, the City Manager, a 5-2-1 Drainage Authority Board member or designee and an employee of the Public Works and Utilities Department. The Hearing Officer or Storm Water Hearing Board shall have the power to:

(1)    Issue in the name of the City Council notices of hearings requiring the attendance and testimony of witnesses and the production of evidence.

(2)    Hold a quasi-judicatory hearing, and receive relevant evidence relating to compliance with the requirements set forth in this chapter. Hearings shall be conducted informally. Rules of civil procedure and evidence shall not solely determine the conduct of the hearing or the admissibility of evidence. All testimony shall be given under oath, and a tape recording or other evidence of the verbatim content of the hearing shall be made. The burden of persuasion in either an appeal or show cause hearing shall be upon the appellant or respondent. The standard of proof to be utilized by the Officer or Board in making its findings or recommendations shall be a preponderance of the evidence.

(3)    Determine and find whether just cause exists for not taking the proposed enforcement actions, or whether the order or action appealed is unwarranted.

(4)    Transmit a report of the evidence and hearing, including transcripts, tapes, and copies of other evidence requested by any party, together with findings and recommendations to all parties to the hearing and to the City Council.

(i)    Findings and recommendations of the Hearing Board or Officer shall be final and binding upon the City Manager and parties to the hearing; provided, however, that if the City Council disapproves the recommendations of the Hearing Board or officer within 30 days thereof, the Council may conduct its own hearing, make its own findings, and issue its own orders. An order consistent with findings and recommendations of the Hearing Board or Officer, or the City Council, as the case may be, shall be issued by the City Manager. The order may provide for imposition of appropriate penalty charges, and for administrative fines designed to reimburse the City for the costs of the permit enforcement action. Further orders and directives, as are necessary and appropriate to enforce the provisions of this chapter may be issued by the City Manager.

(j)    Any person who violates a prohibition or fails to meet a requirement of this chapter will be subject, without prior notice, to one or more of the enforcement actions identified herein, when attempts to contact the person have failed and the enforcement actions are necessary to stop an actual or threatened discharge, which presents or may present imminent danger to the environment, or to the health or welfare of persons or to the well being of the storm drainage system.

(k)    Any person who fails to comply with a notice of violation shall be subject to any of the following:

(1)    The City Manager may issue a stop work order to the owner and contractors on a construction site, by posting the order at the construction site. Unless express written exception is made, the stop work order shall prohibit all further construction activity at the site and shall bar any further inspection or approval(s) necessary to commence or continue construction or to assume occupancy of the site. A notice of violation shall accompany the stop work order, and shall define the compliance requirements.

(2)    The City Manager may order City representatives to terminate an illicit connection to the municipal separate storm sewer system. Any expense related to abatement by City or its contractor(s) or agent(s) shall be fully reimbursed by the property owner. Failure to pay may result in the property being liened as provided herein.

(3)    When a property owner is not available, not able or not willing to correct a violation, the City Manager may order City personnel, contractor(s) or agent(s) to enter private property to take any and all measures necessary to abate the violation. It shall be unlawful for any person, owner, agent or person in possession of any premises to refuse to allow City representatives to enter upon the premises for these purposes. Any expense related to such abatement by City representatives shall be fully reimbursed by the property owner. Failure to pay may result in the property being liened as provided herein.

(4)    Within 30 days after abatement by City representatives, the City Manager shall notify the property owner of the costs of abatement, including administrative costs, and the deadline for payment. If the amount due is not paid, the charges shall become a special assessment against the property and shall constitute a lien on the property for the amount of the assessment plus an administrative charge of 25 percent. The unpaid liens and charges shall be certified to the County Assessor so that the Assessor may enter the amounts of the assessment against the parcel as it appears on the current assessment roll, and the amount of the assessment on the bill for taxes levied against the parcel of land.

(5)    Where necessary for the reasonable implementation of this chapter, the City Manager may, by written notice, order any owner of a construction site or subdivision development to post surety, in a form approved by the City Attorney, not to exceed a value determined by the City Manager to be necessary to achieve consistent compliance with this chapter. The City may deny approval of any building permit, subdivision plat, site development plan, or any other City permit or approval necessary to commence or continue construction or to assume occupancy, until such surety has been filed with the City.

(l)    Any person who violates or continues to violate a prohibition or requirement of this chapter shall be subject to criminal prosecution to the fullest extent of the law and shall be subject to criminal penalties.

(m)    The violation of any provision of this chapter or with any orders, rules, regulations, permits and permit conditions shall be deemed a municipal offense. Any person violating this chapter shall, upon an adjudication of guilt or a plea of guilty or no contest, be punished by a fine or imprisonment or both pursuant to the limits established in GJMC 1.04.090. Each day or portion thereof that any violation of any provision of this chapter exists shall constitute a separate offense.

(1)    If any person violates any order of the City Manager, a Hearing Board or Officer or the Council, or otherwise fails to comply with any provisions of this chapter or the orders, rules, regulations and permits issued hereunder, or discharges into the storm drain system or into State waters contrary to the provisions of this chapter, federal or State requirements, or contrary to any order of the City, the City may commence an action in a court of record for appropriate legal and equitable relief. In such action, the City may recover from the defendant reasonable attorney fees, court costs, deposition and discovery costs, expert witness fees, and other expenses of investigation, enforcement action, administrative hearings, and litigation, if the City prevails in the action or settles at the request of the defendant. Any person who violates any of the provisions of this chapter shall become liable to the City for any expense, loss, or damage to the City or to the storm drain system occasioned by such violation. The City Attorney may seek a preliminary or permanent injunction or both which restrains or compels the activities on the part of the discharger.

(2)    Any person who knowingly makes, authorizes, solicits, aids, or attempts to make any false statement, representation or certification in any hearing, or in any permit application, record, report, plan, or other document filed or required to be maintained pursuant to this chapter, or who falsifies, tampers with, bypasses, or knowingly renders inaccurate any monitoring device, testing method, or testing samples required under this chapter, shall be guilty of a misdemeanor, and upon conviction thereof shall be punished by a fine or imprisonment or both pursuant to the limits established in GJMC 1.04.090.

(3)    The remedies provided for in this chapter, including recovery of costs, administrative fines and treble damages, shall be cumulative and in addition to any other penalties, sanctions, fines and remedies that may be imposed. Each day in which any such violation occurs, whether civil and/or criminal, shall be deemed a separate and distinct offense.
