Joan.Revak Qfj`ice Manager Thank you for the recent conversation regarding the sanitary sewer overflow Clerk of the District (SSO) occurring on dune 18, 2611 at 636 Lakeview Lane, Costa Mesa, located in the Brookview development off Paularino Avenue Robin B. Hamers The sewer overflow occurred due to a blockage in the HOA's private sewer District Engineer (949) 631-1731 main along the west side of the development. The wastewater exited a sewer manhole cover and flowed directly into a storm drain and then into the Orance County Flood Control District Santa Ana Delhi Channel. The Alan R. burns .Regal channel leads to the Upper Newport Bay (Back Bay) in Newport Beach and Counsel then to the Pacific Ocean.. Various methods were used to estimate the volume of effluent and the spill ranged between 25,040-50,000 gallons. Marcxrs.D. Davis Treasurer Sanitary Sewer Overflows (SS)s) are a violation of both the United States Environmental Protection Agency's (EPA) Clean Water Act and the State of California Waste Discharge Requirements Order No. 2006-0003, and the Phone SSO subjects the HOA to possible fines. Addibionally, spills of this (949) 645-8400 magnitude cause immediate closure for three days of downstream waters, Fax in this case, the Back Bay and Pacific Ocean. Beach closures result in a (949) 6:51-2253 three day prohibition of water sports and swimming for both residents and victors and negatively impact tourism. In accordance with Costa Mesa Sanitry District Ordinance No. 81, the 628 �a r' et District may recover the cost of emergency response in responding to a W. 19th Streeet Costa Mesa, CA sewer spill. In that regard, enclosed please find an invoice for the District's 92027-2716 activities, including for C&R Drains, the District's first responder. Please note the HOA's plumber, Coast View Plumbing, was unable to clear the blockage, plus did not respond until Saturday morning after first being called on Friday evening by your office.

These plans were previously emailed to you in pdf format. Per our conversation, you have retained C&R Drains to perform sewer line cleaning of the private sewer system. This is the appropriate first step in a proper operations and maintenance (O&M) program. It is recommended the entire system be cleaned at least once per year and that a camera inspection of the pipeline interior be performed to identify root intrusions, grease buildup, sags, and other locations requiring frequent cleaning. Please pay strict attention to the recommended maintenance measures suggested above as repeat violators are looked upon harshly by the above mentioned regulartory agencies. Please also remember the Costa. Mesa Sanitary District is a resource of sewer system professionals willing to assist you in your sewer system management. Please provide progress reports, either from you or C&R Drains, during the cleaning and televising work on your sewer system. The District also has an array of educatioin/outreach materials, such as the enclosed flyer titled' Proper Disposal of Food, copies of which are free, and which may assist in maintaining free flowing sewers in the development.

This extra protection maximizes CMSD's opportunity to respond immediately to a high water condition. Below are the proposed manhole locations that we believe are the most critical to protecting the environment. Prior to installation of the Smart Covers, staff will meet again to review plans and determine the water elevation that triggers the alarm. Proposed Smart Cover Locations at CMSD 1.

This presentation will give you the tools on how to prepare and ultimately how to respond in an efficient and effective manner. We will discuss the decision making process, the proper utilization of equipment and the most efficient methods for relieving blockages. Having an effective plan for dealing with an emergency response is something that every company and agency should have in place. This seminar will help you develop and implement that plan. Building the Right Image Jim A►anderud, Innerline Engineering Building a successful pipeline inspection and cleaning program requires a particular sensitivity to the perception that others have of us. Projecting the right image does not happen automatically. It requires a well thought out plan that takes into account how to best convey your message of professionalism and competence. In this seminar we will examine specific ways in which we can enhance not only the image we project, but also the quality of the product that we produce. We will challenge individuals to take steps that can help them become leaders in the industry and in their communities.

Qutinn s gins back seat safety belt Chicago's system also dumps untreated sewage into measure iiissto law Lake Michigan during heavy storms. , The federal government has ordered cities to develop plans for how they will limit overflows to no more than four per year or capture 85 percent nf the volume when the systems dooverflow. Most plans must be completed 6y the end of September,to be knuAleomcotcd over specific time period, sooze6ozxo op to two decades, For Chicago,the solution already includes cavernous underground tunnels that hold storm water until it can be pumped to a treatment plant, Belleville is using large lagoons tud*the same thing.Galesburg has four remote treatment facilities to help during storms, and iu separating the pipes that carry sewage and storm water. Communities that don't have approved plans--43im Illinois—are feeling increasing pressure from state and federal environmental officials to get them donw,including violation notices sent to 13 of them,most within the past two years,Illinois EPA officials said. "We put u high priority oathis because it goes tou number mf different issues,including public health,the health of the river system and recreational uses," said Bruce Yurdin, who manages the Illinois EPA's field offices across the state. Fixes won't be cheap,and will require nuuoy uncommoitinm to take out loans and raise sewer and water rates to pay for them. But advocates say the high prict, is an investment with big payoffs for the environment, public health and the economy. Chicago already has spent $3 billion on improvements over the past four decades including tunnels optn35 feet 10 diameter—but still has not stwpp:d the overflows.It plans to spend Si billion more to build two reservoirs,expected to b�completed in 2099, to help. The city cf Belleville plans to spend $8$ million—and likely raise as ' iod water rates over the next 20 years to pay for it—to send overflows 10 two large be held until it can be treated. Overflows go into u creek that isn't o waterway, But the creek empties into the Kaskaskia River,popular, paddlers, said Royce Carlisle, director u[the city's wastewater dbvivi . He said officials also worry about the city's ability to grow if overflows aren't controlled. "We don't want the EPA to say we can't a86 anything to the -, oynt:nu,°he said Galesburg has separated most of its storm and sanitary sewers,built satellite treatment plants 10 neighborhoods and closed off udozen outlets that used to dump wastewater into an open ditch, But overflows still happen--seven to eight times a year in the past three years--because many houses still divert storm water directly to the sewers,said Steve Davis, superintendent ufthe Galesburg Sanitary District, 0o the district will spend an estimated $2.5 million to triple the capacity of lagoon at the oza&o treatment plant,and Davis said u rate increase probably will be needed to pay back any loans used Lo complete the project. Another concern about overflows into waterways is that storm water isn't sinking back into the land and recharging groundwater, Communities should begin looking ut ways to slow or stop storm water[conu getting into sewer systems iu the first place,said Henry Henderson,director rf the Natural Resource Defense Council's Midwest program. Some communities have set aside green space,built plant-covered rooftops and streets that allow water tu soak into the ground.Aurora has done m good job 6y expanding open space and building streetscapes to help control water runoff,Henderson said, .Water is at the heart of sustainability of all our communities,"Henderson said. "Investing in and improving water is not just an environmental issue,but it's about sustainability and the groiArth of the Midwest economy." Despite the costs, the water-quality improvements to date in many communities have been dramatic--and could pay off economically,said the state EPA's Yurdin. In Chicago,some parts of the river have improved so much that it's no longer rare to see schools of paddlers in colorful kayaks, and the banks are lined with restaurants,housing and hotels. In Aurora,the sewer system overflowed ijoo times in 1983,but just 178 times last year, after the city spent $200 Million on controls that included a special treatment plant.It still plans to spend another$120 Million Over 20 years to build another treatment plant and separate more sewers,said Eric Schoeny,an engineer with the city's public works department. Now condominiums are being built along the Fox River,the city is redeveloping a park that will include a canoe launch and entertainment space and anglers are returning to a waterway that barely supported aquatic life 25 years ago--but now yields smallmouth bass and the occasional walleye and northern pike, Schoeny said, "I don't think that would have happened before,"said Schoeny. "After it rained there would be all sorts of disgusting evidence of(combined sewer)discharges. Now I think a lot more people taking advantage of the river and realizing what a great resource it is." Mechanic, the canoeist,says he's seen the payoff first hand along the banks of the Chicago River. "I remember that when my grandparents bought their(Chicago home),the property value was depressed by its proximity to the river,"he said. "Today,the river is so attractive that developers are competing to buy and develop million-dollar condos," AF-"4 F-o6,-25-11192i.GMT Cc,pyrigN w.111 Press.

Fred Crumb suffered critical head injuries in the explosion and never regained consciousness. He died Thursday afternoon, the Shasta County coroner's office confirmed just before 5 p.m, "We're still looking into what happened out there and why,"said Brian Crane, the city's public works director. Crane could not say how long the investigation would last, Nor could he recall another explosion like the one that knocked out Crumb, 54. Crumb was one of five operators at the Clear Creek wastewater treatment plant, which serves about three-quarters of Redding's population. The city is in the middle of an $80 million campaign to upgrade and expand capacity at the plant. The explosion blew the top off a 4,5010-gallon steel hydropneumatic tank, Crane said. The tank was 33 years old. Water enters the tank after it's been chlorinated. From there, the water is distributed throughout the rest of the plant for further treatment, Crane said, Water is pressurized going into and out of the tank, he said. The explosion interrupted the Iplant's treatment process for about two hours, Crane said. Untreated water went into outdoor storage ponds, where there was plenty of room. Crews installed a pump to Ibypass the exploded tank and resume treatment. Crumb worked for the city's wastewater utility since 2004. He worked nine years at treatment plants in other districts around Shasta County, Crane said, "Obviously, Fred was a big part of the city's public works family." Crane said Thursday afternoon.
