ADJOURN AGENDA 1 ESTES VALLEY VICTIM ADVOCATES  6‐Month Report  January 1, 2014 ‐ June 30, 2014    Agency Name                                                                                                                 Estes Valley Victim Advocates, Inc.                         Address    P.O. Box 1287  City                                State                   Zip                           Phone                Estes Park                CO                80517                  577‐9781  Executive Director                                                                         Mary Mesropian                                                              BRIEF PROGRAM DESCRIPTIONS:    ADVOCACY. Victim Advocates (trained and supervised by the Executive Director) and staff  respond to pages from Estes Park Police Department  24 hours a day, 365 days a year.  They  provide emotional support at the time of the incident and assist the victim(s) and their children  in achieving immediate safety and devising safety plans for the future.  They also educate victims  on the judicial process, explain victim rights, inform about victim’s compensation as well as  provide support with the criminal justice process.        COUNSELING. The Counselor counsels victims of crime and trauma. After the initial crisis where  advocates are called, the victim is able to take advantage of the supportive services through  individual counseling and support groups. This short‐term (3‐6 months) crisis counseling is  designed to assist victims return to pre‐crisis state (in the case of sexual assault or other violent  crimes) or to empower them to make changes towards violence‐free living (in the case of  domestic violence.) Children also receive counseling using specific “play therapy”.    BILINGUAL OUTREACH. The Bilingual Outreach Coordinator provides outreach to the Latino  population. The Latino population in Estes Park has grown dramatically in the last few years and  Estes Valley Victim Advocates has hired a part‐time employee to meet the needs of this  population. This position provides education, advocacy and counseling in the form of outreach  to the Latino community. The coordinator is available to assist the Safehouse Manager when  there is need for Spanish language skills.         SAFEHOUSING.  The Safehouse Manager and two safehouse evening advocates are responsible  for ensuring the safety of domestic violence victims in the safehouse. These staff members assist  residents with safety planning, accessing medical, legal and housing programs and making  appropriate referrals.  Food and basic needs are provided to residents and the Safehouse  Manager is responsible for acquiring, stocking and tracking of food pantry, personal items and  household items, for overseeing the day to day upkeep of Safehouse and maintaining the  physical integrity and safety of the Safehouse.       EDUCATION.  Outreach to the community and school system through trainings and programs.        2 OBJECTIVES:    Estes Park police officers page victim advocates and then advocates provide services at the most  appropriate safe location. A Victim Advocate is an immediate and practical assistant. They can  provide emotional support during and after the crisis. Advocates help meet immediate physical  and emotional needs.  If an arrest has been made, a Bond Memo is sent to the District  Attorney’s Office to use in considering bond conditions. This is non‐discoverable to the offender  so the victim can be open without fear of reprisals. A Court Advocate will attend court with the  victim if requested. If safehousing is requested, a danger assessment and client intake report are  conducted.     There are three areas of advocate assessment: Safety, Options and Stability.   These questions are on every advocate case sheet and advocates must answer these questions  on every call:   Is victim(s) physically safe? (Not in immediate danger.)          Victim knows options and rights and knows what to do next?        Is the situation stabilized? This includes emotional stability as well as their ability to take  care of their own and their children’s immediate needs.     All victims are offered individual counseling and support groups. Counseling Program  Assessments are completed by program participants in the form of questionnaires. Safehouse  residents are also asked to complete an assessment needs questionnaire and an exit form  before they leave.      COMMUNITY LIAISON AND NETWORKING ACTIVITIES:    We have Memorandums of Understanding, Contracts or Coordination Agreements with  Crossroads Safehouse in Fort Collins, Alternatives to Violence in Loveland, Larimer County  Sheriff’s Department, Estes Park Medical Center, Rocky Mountain National Park as well as the  Estes Park Police Department. Crossroads Safehouse, Alternatives to Violence and Estes Valley  Victim Advocates meet monthly as part of the Larimer County Domestic Abuse Intervention  Project and as needed to coordinate services. Estes Valley Victim Advocates is also a member of  the Estes Park Child Protection Team to ensure children are protected in our community.      An Estes Valley Victim Advocates’ counselor and a staff person from Estes Valley Restorative  Justice Partnership co‐present an “Impact of Crime” class to all Restorative Justice attendees.        FREQUENTLY ASKED QUESTIONS    How long has Estes Valley Victim Advocates existed?  For over 25 years, Estes Valley Victim Advocates has been supporting the community of Estes  Park and the surrounding Estes Valley. In 1988, the Victim Assistance Program of the Estes Park  Police Department was created as a volunteer component to the police department. Volunteer  advocates were recruited, interviewed and trained and a group of eight advocates began  working. The Victim Assistance program operated under the direction of the Estes Park Police  Department, headed by a program director until 1997 when the program became incorporated.  The Victim Assistance program became Estes Valley Victim Advocates, Inc. In February 2007,  Estes Valley Victim Advocates began offering safehousing for victims of domestic violence. Over  $500,000 was raised through a capital campaign to purchase the safehouse building.     What geography does Estes Valley Victim Advocates serve?  3 Estes Valley Victim Advocates serves the entire Estes Valley including Glen Haven, Allenspark,  Drake and all areas in between including The Retreat and Storm Mountain. We also serve the  Larimer County portion of Rocky Mountain National Park.    Who uses Estes Valley Victim Advocates?  All victims of crime and trauma are welcome to use our advocate services and counseling  program. This includes victims of domestic violence, sexual assault, other crimes as well as  suicide, sudden death and accidents of all kinds. The target population for safehousing is female  victims of domestic violence and their children.      How are advocates notified that there is a crime or trauma victim needing an advocate?  Our local Dispatch alerts a victim advocate on call to respond to police officer at scene, police  department or hospital.      How do victims of domestic violence come into My Sister’s Place?  Sometimes a victim plans to leave and makes arrangements ahead of time. Other times clients  escape violence in the middle of the night. Many times they are referred to My Sister’s Place by  a police officer.     What do the residents do while staying at My Sister’s Place?  Leaving an abusive relationship is a process rather than an event. During their stay, residents  and their children begin rebuilding their lives. For many residents, it’s the first time in a long  time they’ve been able to sleep through the night. Individual counseling and support groups  nurture emotional healing, self‐esteem and self‐sufficiency. Advocates provide assistance with  employment, finances, education, day care and other resources.    How long do residents stay?  Typically residents stay at My Sister’s Place for up to 6 weeks. We do however extend stays if  appropriate, i.e., a lease has been signed but the home will not be available to move into for a  week.    FINANCIAL REPORT:    Operating Grants/Contracts            

Present Situation: Light & Power’s truck #21 is scheduled to (and needs to) be replaced. Specifications for a new truck were developed with the Fleet Department. Two vendors provided quotes: 1. Altec: $219,650 2. Terex: $230,688 Proposal: We propose to accept the low bid for the Altec truck. Advantages: The new truck will improve the work efficiency our line crew with an auger for installation of power poles. Disadvantages: The purchase order will need to be rolled over into 2015. These trucks are built to order and it will take 300 days for delivery. Action Recommended by Staff: Staff recommends approval of the purchase of the Altec truck. Budget: This is a planned and budgeted purchase. There are adequate funds for this purchase in the Vehicle Replacement Fund, account number 635-7000-435.34-42. Level of Public Interest: Low, as not many of our customers follow the types of trucks L&P uses for power line construction and repair. Sample Committee Recommendation: I recommend approval of the purchase of the Altec to the Town Board, to be included on the Consent Agenda at the September 23, 2014, Town Board meeting. WATER DEPARTMENT Memo To: Public Safety, Utilities & Public Works Committee Town Administrator Lancaster From: Water Superintendent Boles Laboratory and Water Quality Supervisor Beehler Date: September 11, 2014 RE: Water Analyzer Purchase – Water Department Objective: Obtain approval for the purchase of a THM analyzer. Present Situation: Control of disinfection by-products is the key element in maintaining compliance with the stage 2 Disinfectants By-Products Rules (DBP rule). We have an increased need for THM test results to improve our treatment process and ensure compliance. The addition of chlorine in the water treatment process creates disinfection by-products when chlorine interacts with total organic carbon (TOC). TOC is a precursor in the formation of disinfection by-products, namely, Trihalomethane (THM) and Haloacetic (HAA5) acids. Trihalomethanes and Haloacetic acids are regulated within the water distribution system at points that will typically represent the longest contact time (water age) for chlorine and TOC. We have purchased a TOC analyzer and received State certification for this analysis. The seasonal nature of our community amplifies water age concerns and, therefore, increases the need for more THM testing. Chlorine is also used in the treatment process at Marys Lake Treatment Plant to reduce seasonal algae taste and odor issues. This adds to our need for THM testing. Proposal: We will purchase the THM analyzer to optimize the treatment process for the reduction of disinfection by-products. Additionally, the THM analyzer will be used to perform more frequent distribution system monitoring (essential because of the seasonal nature of our customer usage) ensuring compliance with the regulated THM levels. Advantages: Acquisition and use of this analyzer would ensure we are in compliance with regulations. Staff time is very limited and these more frequent tests would be performed without having to transport those samples to the valley and waiting for the test results. Disadvantages: Parker Hannifin is the sole manufacturer of THM analyzers. The purchase price for this unit is $35,537.50. Action Recommended by Staff: Staff recommends approval of the purchase of the Parker Hannifin THM analyzer. Budget: This is a planned and budgeted purchase. We have adequate funds for this purchase in the Purification Equipment Capital Account. 503-7000-580.33-40, “PURIFICATION EQUIPMENT” Level of Public Interest Low, as not many of our customers follow the chemistry of water treatment or the implementation of drinking water regulatory compliance. Sample Committee Recommendation: I recommend approval of the purchase of the THM analyzer to the Town Board, to be included on the Consent Agenda at the September 23, 2014, Town Board meeting.

Best Regards, ~/Jc_ Kevin Burke Marketing Manager Instrumentation Products Division The Parker THM Analyzer A drinking water disinfection by-product monitoring system Catalog 4251-THM October 2011 Regulations One such set of regulations – Stage 1 and Stage 2 Disinfectant By-Product Rules (DBPR) – regulate the contaminants formed by disinfecting water with chlorine or chloramine: most notably, Trihalomethanes (THMs) and Haloacetic Acids (HAAs). E ective in 2012, the Stage 2 DBP rule regulates THMs (chloroform, dichlorobromomethane, dibromochlo- romethane, and bromoform) to 80ug/L (80ppb) total concentration. Water treat- ment plants and distribution systems are required to implement this rule and meet THM levels at each monitoring site in the distribution system. To reach this level, water plants must monitor THM levels to optimize their treatment process. Current Practices Today, many drinking water facilities rely on outside laboratory analysis for THM monitoring. Although this data is reliable and accurate, the time it takes to receive THM data and the high cost per sample make outside lab analysis impractical for real-time optimization of water treatment processes. Plant operators require immediate data to adjust the pH, coagulant, and disinfectant dosage that impact THM formation. Reliable and timely THM data is essential for water treatment process optimization. The demand for clean, reliable drinking water has and will continue to be of primary concern for consumers in the U.S. and around the world. In the U.S., 90% of people receive their drinking water through a public water system, where contaminants are regulated by the Safe Drinking Water Act (SDWA), as regulated by the U.S. EPA. THM ANALYSIS – VITAL FOR DRINKING WATER SAFETY AND COMPLIANCE The Drinking Water Treatment Process In coagulation, alum and lime are added to form easily settleable fl oc. During sedimentation, the fl oc settles to the bottom and the clear water moves to fi ltration. In fi ltration, fi lters made of sand, gravel, and charcoal help remove even smaller particles. During disinfection, chlorine or chloramine is added to kill any bacteria or microorganisms. 3 THE PARKER THM ANALYZER Rapid measurement of THMs when, where, and as often as you want – with immediate results.

THM levels can be lowered through- out the distribution system and chemical usage can be optimized to save money. What’s more, quick process adjustments can be made to control THM formation when surface water Total Organic Carbon (TOC) characteristics alter due to seasonal or unusual weather conditions. Where before you might have had limited THM data, you can now greatly expand the sampling frequency and monitoring locations to help you better understand the THM formation characteristics of your water source, treatment process, and distribution system. Surface Water Supply Matrix Changes Both human activities and seasonal changes can a ect source water, altering the mineral characteristics of the water as well as the reactivity of its dissolved organic carbon. A water plant may observe no signi cant changes in the quantity of TOC due to seasonal events, but they may nd their THM level has changed. Frequent measurements of THM can help operators better understand the reactivity changes of their source water. 7 THM ANALYSIS – APPLICATION OPPORTUNITIES Real-Time Monitoring of THM Sampling Locations Trihalomethane formation in water distribution systems is a function of water travel time, temperature, and physiochemical and biological characteristics of pipe deposits within the distribution system. The real-time monitoring of THM at different sampling locations will help water distribution operators to identify problematic inorganic/organic pipe deposits that cause increased levels of THM formation. 8 THM ANALYSIS – APPLICATION OPPORTUNITIES Coagulant Evaluation Test A successful coagulation process depends on identifying the correct coagulant type and optimum dosage under suitable environmental condi- tions of pH and alkalinity such that the coagulant will remove the maximum TOC, UV254, and turbidity, and form easily settleable oc. However, without the ability to mea- sure THM concentration of the nished water in real time, the plant operator will not know if the coagulation process has been optimized to also remove the maximum amount of THM precursors. With the ability to easily measure THM concentration in fi nished water, the plant operator can adjust the co- agulation process to achieve minimal THM formation potential. Addition- ally, this allows the treatment plant to supply safe drinking water with the required level of disinfectant concen- tration while also maintaining lower DBP levels throughout the entire distribution system. Flushing Program Water quality levels throughout the distribution system are maintained by systematic ushing programs designed to reduce stationary water in dead end lines and increase ow volume to minimize water age. e distance of water from the water plant, dead ends in the pipe, and low water usage may cause water quality deterioration. Lower residual disinfectant levels indicate the need to ush, which can cause a signi cant water loss. By measuring THM con- centration in addition to disinfectant levels, operators can better decide on the location and length of fl ushing to minimize treated water loss. Water Age Evaluation Water age is emerging as an important issue due to increased THM formation in water distribution systems. Exces- sive contact time caused by dampened peak-hour demands, distribution piping con gurations, areas of reduced water requirements, and re protection storage can result in elevated THM concentra- tion. Identifying and then reducing dead spaces and stagnation in water storage tanks and looping pipe con gurations in water distribution systems will reduce water age. These actions can be trig- gered appropriately by monitoring THM levels in storage tanks and key locations in the distribution system. 9 Water Quality Model Evaluation/Water Quality Trend Hydraulic modeling of a water distribution system is an im- portant tool for water quality management. In addition to basic hydraulic characteristics, modeling identi es water aging and predicts disinfectant decay and DBP formation. Incorporat- ing new data from frequent THM analysis in combination with disinfectant level data will help plant operators build an improved hydraulic model for water quality trend analysis, providing critical information for more targeted and effi cient water plant operation.
