TWENTY-FOURTH LEGISLATURE, 2007

 

STATE OF HAWAII

 

 

 

 

 

A BILL FOR AN ACT

 

 

relating to dam safety.

 

 

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF HAWAII:

 


     SECTION 1.  On March 14, 2006, just before dawn, Ka Loko dam on the island of Kauai breached.  Almost 400,000,000 gallons of water -- 1,600,000 tons -- came crashing down from the Ka Loko reservoir into Kilauea bay, taking trees, cars, buildings, and human lives with it.  It was a great human tragedy and an ecological disaster.

     The legislature finds that a subsequent investigation began approximately August 1, 2006, and concluded with a report published January 7, 2007:  Report of the Independent Civil Investigation of the March 14, 2006, Breach of Ka Loko Dam.  Among its findings, the report notes that a significant portion of Hawaii's contemporary surface water system is made up of antique earthen dams and waterways from the plantation era.  The majority of dams in Hawaii were developed to support the sugarcane industry, but many small farmers still utilize water from these old reservoirs today.  While the sugar industry could afford to devote significant resources to maintaining the irrigation systems vital to its success, that industry is now largely gone and the water systems have suffered as a result.

     The purpose of this Act is to implement recommendations from the report.

     SECTION 2.  The Hawaii Revised Statutes is amended by adding a new chapter to title 12 to be appropriately designated and to read as follows:

"Chapter

hawaii dam and reservoir safety

PART I.  GENERAL PROVISIONS

     §   -1  Short title.  This chapter shall be known and may be cited as the "Hawaii Dam and Reservoir Safety Act of 2007".

     §   -2  Declaration of purpose.  (a)  The purpose of this chapter is to provide for governing the design, construction, operation, maintenance, enlargement, alteration, and repair of dams, reservoirs, and appurtenant works in the State.

     (b)  This chapter shall not apply to the design and construction of dams, reservoirs, and appurtenant works that already existed on February 1, 2007, but shall apply to their operation, maintenance, enlargement, alteration, repair, and removal.

     (c)  This chapter shall not apply to any artificial barrier that is less than six feet in height regardless of storage capacity, or that has a storage capacity at maximum water storage elevation less than fifteen acre-feet regardless of height, unless the barrier, due to its location or other physical characteristics, is a high hazard or moderate hazard potential dam.

     §   -3  Definitions.  As used in this chapter unless otherwise provided:

     "Alteration" means a change to an existing dam or reservoir from the originally approved construction plans and specifications or current condition.

     "Application approval" means authorization in writing issued by the board to an owner who has applied to the board for permission to construct, enlarge, repair, alter, remove, maintain, or operate a dam and that specifies the conditions or limitations under which work is to be performed by the owner or under which approval is granted.

     "Appurtenant works" means the ancillary features of a dam, such as the spillway, reservoir and its rim, powerhouse outlet, tunnel, pipeline, and penstock.

     "Authorization" means written acknowledgement form the department to proceed with proposed actions.

     "Board" means the board of land and natural resources.

     "Certificate of approval to impound" means authorization in writing issued by the board to an owner who has completed construction, enlargement, repair, or alteration of a dam and that specifies the conditions or limitations under which the dam and reservoir are to be maintained and operated.

     "Dam" means any artificial barrier, including appurtenant works, which impounds or diverts water, and which:

     (1)  Is twenty-five feet or more in height from the natural bed of the stream or watercourse measured at the downstream toe of the barrier, or from the lowest elevation of the outside limit of the barrier if it is not across a stream channel or watercourse, to a maximum water storage elevation; or

     (2)  Has an impounding capacity at maximum water storage elevation of fifty acre-feet or more.

     "Dam rehabilitation loan program" means a low interest revolving dam rehabilitation loan program.

     "Day" means calendar days, including Saturdays, Sundays, and holidays.

     "Department" means the department of land and natural resources.

     "Design water level" means the maximum water elevation, including the flood surcharge, which a dam is designed to withstand.

     "Emergency" includes, but is not limited to, breaches and all conditions leading to or causing a breach, overtopping, or any other condition in a dam and its appurtenant structures that may be construed as unsafe or threatening to life or property.

     "Engineer" means a qualified professional engineer who has a background in civil engineering and:

     (1)  Is a licensed engineer;

     (2)  Is competent in areas related to dam investigation, design, construction, and operation for the type of dam being investigated, designed, constructed, or operated;

     (4)  Understands adverse dam incidents, failures, and the potential causes and consequences of failures; and

     (5)  Continues with necessary training to keep abreast of the state of the practice in dam safety engineering.

     "Enlargement" means any change in or addition to an existing dam or reservoir that raises or may raise the maximum water storage elevation of the reservoir.

     "Hazard potential" means the possible adverse incremental consequences that result from the release of water or stored contents due to failure of the dam or mis-operation of the dam or appurtenances.  The hazard potential classification of a dam does not reflect in any way on the current condition of the dam and its appurtenant structures, such as safety structural integrity and flood routing capacity.

     "High hazard" means a dam's failure will probably cause loss of human life.

     "Low hazard" means a dam's failure will result in no probable loss of human life and low economic or environmental losses; provided that economic losses are principally limited to the owner's property.

     "Maximum water storage elevation" means the maximum water surface elevation of the reservoir at the crest of the spillway or, if no spillway exists, at the crest of the dam.

     "Moderate hazard" means a dam's failure will result in no probable loss of human life but may result in major economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns.  Moderate hazard potential classification dams are often located in predominantly rural or agricultural areas but could be located in areas with population and significant infrastructure.

     "Owner" means any person who has a right, title, or interest in, or to the dam, or to the property upon which the dam or appurtenant works is located or proposed to be located.

     "Person" includes any natural person, partnership, firm, association, organization, corporation, municipality, municipal authority, trust, receiver or trustee, limited liability company, limited liability partnership, or company or any state department, agency, or political subdivision, or any other commercial or legal entity.  Whenever used in a section prescribing and imposing a penalty or sanction the term "person" includes the members of an association or organization, and the officers of a corporation, company, county or county authority.

     "Probable" means more likely than not to occur; reasonably expected; realistic.

     "Removal" means complete elimination of the dam embankment or structure to restore the approximate original topographic contours of the valley.

     "Repair" means construction to an existing dam that does not significantly change the reservoir's storage capacity.  Repair shall not be deemed to apply to routine maintenance not affecting the safety of the structure.

     "Reservoir" means any basin that contains or will contain water impounded by a dam.

     "Spillway" means a device that safely diverts the flood of a dam without endangering its safety or integrity.

     "Spillway crest" means the lowest level at which water can flow over or through the spillway.

     "Storage capacity" means the total reservoir storage acre‑feet at the maximum water storage elevation.

     §   -4  Exempt structures.  Structures exempt from this chapter include:

     (1)  Highways and roadfills (except those designed or modified with the purpose of impounding water for uses other than flood detention);

     (2)  Dams smaller than those defined in section    -3;

     (3)  Dams for which no loss of human life is expected and damage will occur only to the owner's property in the event of failure of the dam;

     (4)  Refuse embankments (e.g., solid waste disposal facilities); and

     (5)  Structures that store water only below the lowest point of the natural ground, unless an outlet works is constructed to develop water.

     §   -5  Violations; penalties.  (a)  Any person who violates any provision of this chapter shall be liable for a civil penalty not to exceed $10,000 per day of the violation, and each day during which the violation continues shall constitute an additional, separate, and distinct offense.

     §   -24  Completion of removal of dam or reservoir.  (a)  Upon completion of the removal of a dam or reservoir, the owner shall file with the department a report regarding the manner in which the work was performed and the removal of the dam.  No filing routine drawdown of reservoirs maintenance not affecting the conditions existing after shall be required for the normal operations and safety of the structure.

     (b)  The report shall show that a sufficient portion of the dam has been removed to permit the safe flow of water down the watercourse across or around which the dam was situated and that adequate provisions have been made by the owner to prevent any damage downstream that may result from the remaining portion of the dam due to subsequent flooding.

     §   -25  Certificates of approval to impound.  (a)  Each dam owner shall hold a valid certificate of approval to impound in order to legally impound water under the laws of this State.

     (b)  An application for a certificate of approval to impound for any dam not having an application approval to construct, enlarge, alter, or repair a dam or reservoir shall be made on forms available from the board.  An application for a certificate of approval to impound is not required for dams already having an application approval to construct, enlarge, alter, or repair.  Any dam owner who is notified by the board of the need to apply for a certificate for approval to impound shall submit such application within thirty days of the notification.

     (c)  A certificate of approval to impound shall be issued by the board upon a finding by the board that the dam and reservoir are safe to impound water within the limitations prescribed in the application approval.  No water shall be impounded by a dam or reservoir prior to issuance of a valid certificate of approval to impound; provided that pending issuance of a new or revised certificate of approval to impound, the owner of the dam or reservoir shall not cause the dam or reservoir to impound water beyond the limitations or conditions prescribed in the existing certificate of approval to impound.

     (d)  The board shall revoke, suspend, or amend any certificate of approval to impound whenever it determines that the dam or reservoir constitutes a danger to life and property.  Upon the board's revocation of a certificate to impound, the owner of the dam shall take action within time limits specified by the board to alleviate the hazard associated with the dam.

     (e)  Certificates of approval to impound are not transferable from one person to another or from one dam to another.

     (b)  In determining whether an existing dam or reservoir or proposed dam or reservoir constitutes or would constitute a danger to life or property, the department shall evaluate the possibility that the dam or reservoir might be endangered by overtopping, seepage, settlement, erosion, cracking, earth movement, earthquakes, and failure of bulkheads, flashboard, gates, and conduits that exist or that might occur in any area in the vicinity of the dam or reservoir.

     (c)  If an unsafe condition exists, the department shall notify the owner to take action necessary to render the condition safe, including breaching or removal of any dam found beyond repair.  If the owner is unavailable or unresponsive, the board may commence action under section    -32.

PART IV.  MAINTENANCE AND OPERATION

     §   -31  Maintenance and operation.  (a)  Owners shall provide for the adequate and timely maintenance, operation, and inspection of their dams and reservoirs and shall be responsible for any engineering and geologic investigations that may be required to ensure public safety.  Owners or their agents shall keep available and in good order records of original construction and any modifications, and shall report to the department their maintenance, operation, and engineering activities, including horizontal and vertical controls, seepage measurements, piezometric data collection, and geologic investigations.

     (b)  The owner of a dam or reservoir or the owner's agent shall fully and promptly advise the department of any sudden or unprecedented flood or unusual or alarming circumstance or occurrence existing or anticipated that may adversely affect the dam or reservoir.

     (c)  The department, from time to time and without prior notice to the owners of dams and reservoirs, but not less than once every three years for high hazard and moderate hazard dams, and not less than once every five years for low hazard dams, either with its own engineers or by consulting engineers of its selection, shall make inspections of dams and reservoirs at the owner's expense for the purpose of determining their safety.  The department shall require owners to perform at their expense any necessary remedial work and work reasonably required to disclose information sufficient to enable the department to determine conditions of dams and reservoirs in regard to their safety, including the installation, maintenance, and monitoring of necessary instrumentation.  As part of the inspection, the department shall periodically review the classification of the dams by evaluating the consequences of failure applying the definitions of section    -3.

     (d)  All costs incurred by the department to conduct the inspection shall be charged to the owner.  The department shall present a bill for the expenses to the owner, and if the owner neglects for thirty days thereafter to pay it, the bill and costs become a lien upon the lands and property of the owner so liable for the payment of the bill, and shall be collected as delinquent taxes against the lands and property are collected.

     §   -32  Emergency work.  (a)  Owners of dams and reservoirs have the primary responsibility for determining when an emergency involving a dam or reservoir exists.  When the owner of a dam or reservoir determines an emergency exists, the owner shall immediately implement the emergency preparedness plan required by section    -33, notify any persons who may be endangered if the dam should fail, notify emergency management organizations, and take additional actions necessary to safeguard life, health, and property.

     (b)  In case of an emergency where the department declares that repairs, breaching of the dam, or other actions are immediately necessary to safeguard life and property, the work shall be initiated by the owner, or by the department through its authorized agent at the owner's expense if the owner fails to do so.  The department shall be notified at once of any emergency repairs or other work instituted by the owner.

     (c)  In applying the remedial means provided for in this section, the department in an emergency with its own forces, or by other means at its disposal, may do any or all of the following:

     (1)  Take full charge and control of any dam or reservoir;

     (2)  Lower the water level by releasing water from the reservoir;

     (3)  Completely drain the reservoir;

     (4)  Perform any necessary remedial or protective work at the site; or

     (5)  Take such other steps as may be essential to safeguard life and property.

     (d)  The department shall continue in full charge and control of the dam and reservoir and its appurtenances until they are rendered safe or the emergency occasioning the action has ceased and the owner is able to take back the operations.  The department's take-over of the dam, the reservoir, or their appurtenances shall not relieve the owner of a dam or reservoir of legal liability to the department or third parties for those items that are causing an emergency situation.  The department's assumption of control over the dam shall not constitute a takings and the department shall not be liable to the dam owner or others for diminution in value that may be caused by the department's work.

     (e)  The cost and expense of the remedial means provided in this part, including cost of any work done to render a dam and reservoir or its appurtenances safe, shall be collected by presentation of bills to owners in the same manner as other debts to the State are recoverable.  If the bills are not promptly paid by the owners, the cost shall be recovered by the state from the owner by action brought by the department in a court of appropriate jurisdiction, shall become a lien upon the lands and property of the owner so liable for the payment of the bill, and shall be collected as delinquent taxes against the lands and property are collected.

     (f)  Where appropriate, the repairs, breaching, or other emergency work shall conform to an order issued by the department.

     (g)  The following emergency actions not impairing the safety of the dam may be taken by the owner without prior notification or approval of the department:

     (1)  Stockpiling materials such as riprap, earthfill, sand, sandbags, and plastic sheeting;

     (2)  Lowering the reservoir level by making releases through the outlet or a gated spillway, by pumping or by siphoning; provided that, when large releases are to be made, the department shall be notified.  Lowering the water level by excavating the spillway or embankment is prohibited unless failure is imminent.  In this situation, the department shall be notified as soon as reasonably possible of any emergency condition that exists and any emergency action taken;

     (3)  Armoring eroded areas by placing sandbags, riprap, plastic sheeting, or other available material;

     (4)  Plugging leakage entrances on the upstream slope;

     (5)  Increasing freeboard by placing sandbags or temporary earthfill on the dam;

     (6)  Diverting floodwaters to prevent them from entering the reservoir basin;

     (7)  Constructing training berms to control floodwaters;

     (8)  Placing sandbag ring dikes around boils at the downstream toe to provide back pressure; and

     (9)  Removing obstructions from outlet or spillway flow areas.

     §   -33  Emergency preparedness plan.  (a)  Owners of high hazard and moderate hazard dams shall prepare, maintain, and implement an emergency preparedness plan for each dam or reservoir for immediate defensive action to alert and evacuate the affected population and mitigate damages to property.  The emergency preparedness plan shall be submitted to the board for review and acceptance.  The board may issue an acceptance after determining the emergency preparedness plan is substantially complete.  The emergency preparedness plan shall contain as a minimum the following:

     (1)  The identification of equipment, labor, and material available for implementation of the plan;

     (2)  A notification procedure for informing the department and the civil defense office of the affected county;

     (3)  A dam failure inundation map; and

     (4)  A procedure for warning the affected population if failure of the dam is imminent.

     (b)  The owner shall submit a copy of the emergency preparedness plan to the affected county civil defense office and other emergency coordinators involved in the plan for review.

     (c)  The owner shall annually review and update the emergency preparedness plan as necessary.

     §   -34  Change in ownership.  Changes in ownership of a dam shall be immediately filed with the department.

PART V.  FEES

     §   -41  Filing fees.  (a)  The owner shall submit with the application for construction, enlargement, alteration, repair or removal an amount equal to $3 for each $1,000 or fraction thereof of the estimated cost of construction including engineering costs, but the maximum fee shall not exceed $3,000, nor shall the minimum fee be less than $100.

     (b)  For the purposes of this chapter, the estimated cost of the construction, enlargement, alteration, repair, or removal shall include the following:

     (1)  The cost of all labor and materials entering into the construction of the dam and appurtenant works or reservoir;

     (2)  The cost of preliminary investigations and surveys;

     (3)  The cost of the construction plant properly chargeable to the cost of the dam or reservoir; and

     (4)  Any and all other items entering directly into the cost of the construction, enlargement, alteration, repair or removal.

     (c)  The costs of right-of-way, detached powerhouses, electrical generating machinery, and roads and railroads affording access to the dam or reservoir shall not be included among the items used in the determination of cost.

     (d)  An application shall not be considered by the department until the filing fee is received.

     (e)  If the actual cost exceeds the estimated cost by more than fifteen per cent, a further fee shall be required by the board before final approval and shall be one hundred fifteen per cent of the amount by which the original fee is less than it would have been had the cost it was based upon been the same as the actual cost.  No further fee shall be required, however if such fee is to be computed at less than $20.

     §   -42  Annual fees.  (a)  An annual fee shall be paid by the owner of the dam on or before December 31, 2007, and on or before December 31 of each succeeding year, based upon a fixed rate and height of the dam.  The annual fee shall be $           per dam, plus $           per foot of height.

     (b)  Any owner who fails to pay any annual fee or any part of any annual fee required to be paid within the time required shall pay a penalty of ten per cent of the annual fee or part of the annual fee, plus interest at the rate of one-half of one per cent per month, or fraction thereof, from the date on which the annual fee or the part of the annual fee became due and payable to the State until the date of payment.

     (c)  For the purposes of this section, "height of the dam" means the vertical distance, to the nearest foot, from the natural bed of the stream or watercourse at the downstream toe of the barrier, as determined by the department, or from the lowest elevation of the outside limit of the barrier, as determined by the department, if it is not across a stream channel or watercourse, to the maximum possible water storage elevation."

     SECTION 3.  If any provision of this Act, or the application thereof to any person or circumstance is held invalid, the invalidity does not affect other provisions or applications of the Act, which can be given effect without the invalid provision or application, and to this end the provisions of this Act are severable.
