the cursory inspection included a scattering of artifacts. An archaeological survey and consultation with SHPD is expected as a next step. • Closure of the large capacity cesspools as mandated by the EPA will occur once the treatment and disposal system has been constructed and properties have been connected to the new collection system. • The project is funded by Clean Water State Revolving Funds (CWSRF) monies and partially by a federal EPA grant. C. NORTH KONA SEWER & EFFLUENT REUSE UPGRADE: • The wastewater portion of the State Highway Widening Project construction work is approximately 80% complete. The remaining wastewater work consists of installing sewer and reuse laterals. • The revised draft Memorandum of Understanding (MOU) for the last re-design and additional construction cost attributed to project delays for the sewer and reuse lines is with the State Attorney General for final review. • The State DOT began the overall project construction in September 2015. Currently, the anticipated completion date is August 2018. The project continues with installation of reuse piping and gravity sewer lines. • The project is funded by Clean Water State Revolving Fund (CWSRF) monies. D. LONO KONA SEWER IMPROVEMENT DISTRICT: • A construction pre-bid meeting took place on December 20, 2017. Bid opening is scheduled for January 29, 2018, at 2:00 pm. • Loan closing is scheduled to occur sometime during the first quarter of 2018 prior to bid advertising. Construction NTP is estimated to be issued in mid- 2018. • The USDA Rural Development has obligated loan and grant funds of $2,437,000 and $4,024,800 respectively to this project. E. KEALAKEHE AERATION UPGRADE AND SLUDGE REMOVAL: • Project completion is to take place in early January. • Monitoring of endangered bird species continues. The project is in the midst of the breeding season which will delay the project. • The purpose of this project is to replace the existing aeration blowers with units that will save on electrical energy costs and be quieter. Estimated annual electrical cost savings is $370,000 per year. The new blowers are currently installed, with start-up to occur pending completion of electrical work. Combined with the removal of accumulated sludge from the aerated lagoons, it will restore biological treatment capacity and also allow the County to utilize the full capacity of the aerated lagoons treatment system as the community grows as projected for the next 20 years. • The construction phase scope of work also includes (among other items) replacement of aeration piping and diffusers, dredging and dewatering wastewater sludge (biosolids) within the construction premises; hauling the dewatered sludge to be disposed of at the Pu‘uanahulu Landfill; and implementing mitigation measures during construction to protect endangered bird species. 3
