PW-M&O AN ORDINANCE AMENDING TITLE 13, CHAPTER 13.04, SEWERS; GENERAL REGULATIONS, OF THE CARLSBAD MUNICIPAL CODE REGARDING RESPONSIBILITY FOR MAINTENANCE AND REPAIR OF SEWER LATERALS DEPT. HEADdj^«*iu CITY ATTY. (jj^ ^^IT\X HJI ^^^5 ^^\\^^VL»l 1 Y MoK. Q^VJJLJ ^ RECOMMENDED ACTION: Introduce Ordinance No. NS-851 amending Title 13, Chapter 13.04 (Sewers; General Regulations) of the Carlsbad Municipal Code to clarify that private property owners be the responsible party for maintenance and repair of sewer laterals and to assist private property owners in emergencies involving sewer laterals in order to reduce sanitary sewage from entering the environment. ITEM EXPLANATION: Sewer laterals are that portion of sewer pipes which carry sanitary sewage and/or industrial wastes from a building to the public sewer. The public sewer conveys wastewater to a publicly owned treatment works (POTW). The proposed action formally clarifies the responsibility to maintain, inspect and repair privately-owned sewer laterals by private property owners or parcel occupants/users. The city would respond to overflows at privately-owned sewer laterals when the responsible party was unavailable, incapable and/or unwilling to abate the discharge and when immediate action is necessary to preserve or protect the public health, safety and/or the environment. The responsible party would be charged for the costs incurred by the city for this response. This action was brought forward to Council for consideration in 2004 and failed due to lack of a majority. It has been the practice of the city to respond to sewer-related issues that affect public health and safety concerns. The city has continued to respond to overflows caused by blockages or breaks at private laterals as a low-cost courtesy to the customer. In May of 2006, a General State-wide Order, commonly referred to as the Waste Discharge Requirement (WDR), was adopted and significantly changes the cost of continuing to provide this service. Order No. 2006-03-DWQ (WDR), issued by the State Water Resources Control Board, pertains to Waste Discharge Requirements for Sanitary Sewer Systems. All federal agencies, cities, counties, municipalities and districts that own or operate sanitary sewer systems greater than one mile in length or which collect and/or convey wastewater to a Publicly Owned Treatment Works (POTW), are required to comply with the Order. The overriding goal of the Order is to ensure that overflows from the sanitary sewer are reduced statewide. Additionally, because domestic sewage can contain high concentrations of disease-carrying organisms, nutrients, oxygen-demanding organic compounds and other pollutants, Sanitary Sewer Overflows (SSOs) can contribute to beach closures, impair environmentally sensitive surface waters and aquatic life and create public nuisances. The elimination of overflows and having a plan in place to mitigate overflows will result in decreasing the risk to human health and to the environment. FOR CITY CLERKS USE ONLY. COUNCIL ACTION: APPROVED DENIED CONTINUED WITHDRAWN AMENDED ^D D D D CONTINUED TO DATE SPECIFIC CONTINUED TO DATE UNKNOWN RETURNED TO STAFF OTHER -SEE MINUTES D D D D Page 2 One of the elements of the State's Order specifies that agencies be responsible for the maintenance, inspection and repair of the sanitary sewer system including laterals, that is owned (such as sewer mains) or maintained by the agency. The Order also specifies that all reasonable steps be taken to contain and prevent SSOs from entering the storm drain and receiving waters. Reasonable steps include ongoing visual and TV inspection of lateral pipes, cleaning of the laterals on a regular basis and installation of clean-outs to access and perform the work. Staff estimates that half of the 22,166 private sewer laterals in the city were installed prior to standards requiring cleanout installation, necessitating installation of approximately 11,083 cleanouts. Costs are approximately $2,000 per lateral installation with collective one-time costs in excess of $22.2 million. It is the norm, rather than the exception, for property owners to be responsible for the maintenance of private sewer laterals to the sewer main. The fact that part of the sewer lateral is located under a public street does not mean that it is of public benefit, nor should the maintenance and repair of the lateral be performed by City forces at the expense of ratepayers. In almost all cases, the owner of the private property holds the underlying fee title to the center of the street. The public street is an easement. Clarifying that private property owners have the responsibility for maintenance and repair of sewer laterals would bring the city's policy in line with the Leucadia Wastewater District and Vallecitos Water District, which serves some of Carlsbad's residents in the southern area of the City and would result in consistent services provided to all Carlsbad residents. Private property owners need to keep their sewer laterals clear of blockages, repair damaged lines on their property and install cleanouts, as necessary, to perform maintenance. Blockages can be reduced by planting trees and bushes away from private laterals and by practicing good grease disposal methods such as collecting grease and disposing of it in the trash. The proposed action is one of several requirements of the General State-wide Order clarifying legal authority for maintenance, inspection or repairs and brings the city closer to meeting the milestone date for development of a comprehensive Sewer System Management Plan (SSMP) pertaining to proactive operation, maintenance and management of the sewer system. The final SSMP must be developed, implemented and adopted by August of 2009. Staff has completed milestones related to electronic spill reporting and application for mandated permit coverage under the Order. Near-term milestones designating lines of authority for spill reporting and a SSMP development plan and schedule were completed in May of this year. Other elements of the SSMP involve development of a program to limit the discharge of fats, oils and greases, implementing a continuing process to identify and correct problems, updating our existing Overflow Emergency Response Program, updating our CIP to ensure adequate capacities for flows, additional ordinance updates, staff training, ongoing visual and TV inspection and final adoption by the City Council. A comprehensive SSMP task list is attached as Exhibit 1. The City is also obligated to communicate its progress in developing and implementing the SSMP, as well as on the performance of the SSMP. Staff has met internally with Communications personnel and has proposed to send mailers and to post progress and performance on the City's internet site. A dedicated phone line, e-mail address or community meetings may also be used as further means of communication and for public input. Staff recommends that the City Council take the following actions: (1) Approve and adopt Ordinance No. NS-851 . an ordinance identifying the property owner as the party responsible for maintenance and repair of the sewer lateral and allowing for immediate action when necessary to preserve or protect the public health, safety and/or the environment in order to reduce sanitary sewage from entering the environment; and (2) direct staff to establish an outreach program to provide information to the public on the affects of Ordinance No. NS-851 . on property owners, including suggested preventative sewer lateral maintenance practices and development and performance of the SSMP. PageS ENVIRONMENTAL IMPACT: The proposed action is categorically exempt from the California Environmental Quality Act (CEQA). Section 15301 of the State CEQA Guidelines exempts the repair, maintenance, or minor alteration of existing public or private structures, and mechanical equipment involving negligible or no expansion of use. FISCAL IMPACT: If the City Council approves Ordinance No. NS-851. the fiscal impact is the cost of an outreach program to educate the public regarding preventative sewer lateral maintenance practices and progress with the SSMP. The cost for this program is estimated to be $10,000 for the first year with ongoing costs of approximately $10,000 until the SSMP is completed in 2009 and $5,000 per year thereafter. There are sufficient funds in the Sewer Enterprise Fund Operating Budget to cover these costs. If the City Council does not approve the Ordinance, significant costs will be incurred. Staff estimates it would cost approximately $500,000 annually for cleaning, maintenance and TV video inspection plus associated repairs, materials and equipment, and liability exposure. In addition to the annual cost, the most significant cost would be a one-time expense of approximately $22.2 million associated with clean-out installation on the substandard laterals. The sewer operating fund currently does not have adequate funds to pay for these costs, and a detailed financial analysis would be required, should Council select this alternative. EXHIBITS: 1.
