"Composite Correction Program" or "CCP" consists of a Comprehensive Performance Evaluation (CPE) and Comprehensive Technical Assistance (CTA), both performed by a state-approved third party. "Comprehensive Performance Evaluation" or "CPE" means a thorough review and analysis of a treatment plant's performance-based capabilities and associated administrative, operation, and maintenance practices. It is conducted by a state-approved third party to identify factors that may be adversely impacting a plant's capability to achieve compliance and emphasizes approaches that can be implemented without significant capital improvements. The CPE must consist of at least the following components: assessment of plant performance; evaluation of major unit processes; identification and prioritization of performance limiting factors; assessment of the applicability of comprehensive technical assistance (CTA); and preparation of a CPE report. "Comprehensive Technical Assistance" or "CTA" means the performance improvement phase that is implemented if CPE results indicate improved performance potential. During the CTA phase, the system must identify and systematically address plant-specific factors. The CTA is a combination of utilizing CPE results as a basis for follow up, implementing process control priority-setting techniques, and maintaining long-term involvement to systematically train staff and administrators. "Confluent growth" means a continuous bacterial growth covering the entire filtration area of a membrane filter, or a portion thereof, in which bacterial colonies are not discrete. "Consecutive system" is a public water system that receives some or all of its finished water from one or more wholesale systems. Delivery may be through a direct connection or through the distribution system of one or more consecutive systems. "Contaminant" means any physical, chemical, biological, or radiological substance or matter in water. An additive contaminant under this definition may have a beneficial or a detrimental effect on the potability of the water. "Conventional filtration treatment" means a 20-6 3376 §11-20-2 series of processes including coagulation, flocculation, sedimentation, and filtration resulting in substantial particulate removal. "CT" or "CTcalc" is the product of "residual disinfectant concentration" (C) in milligrams per liter or mg/l determined before or at the first customer, and the corresponding "disinfectant contact time" (T) in minutes, i.e., "C" x "T". If a public water system applies disinfectants at more than one point prior to the first customer, it shall determine the CT of each disinfectant sequence before or at the first customer to determine the total per cent inactivation or "total inactivation ratio." In determining the total inactivation ratio, the supplier shall determine the residual disinfectant concentration of each disinfection sequence and corresponding contact time before any subsequent disinfection application point(s). "CT99.9" means the CT value required for 99.9 per cent (3-log) inactivation of Giardia lamblia cysts. "CT inactivation ratio" means (CTcalc)/(CT99.9). The sum of the inactivation ratios, or total inactivation ratio shown as (CTcalc)/(CT99.9) is calculated by adding together the inactivation ratio for each disinfection sequence. A total inactivation ratio equal to or greater than 1.0 is assumed to provide a 3-log inactivation of Giardia lamblia cysts. "Department" means the department of health, State of Hawaii. "Diatomaceous earth filtration" means a process resulting in substantial particulate removal in which (1) a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and (2) while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake. "Direct additives" means contaminants added to water in the protection of drinking water. "Direct filtration" means a series of processes including coagulation, flocculation, and filtration but excluding sedimentation resulting in substantial particulate removal. "Director" means the director of the Hawaii state department of health or the director's authorized agent. 20-7 3376 §11-20-2 "Disinfectant contact time" ("T" in CT calculations) means the time in minutes that it takes for water to move from the point of disinfectant application or the previous point of disinfectant residual measurement to a point before or at the point where residual disinfectant concentration ("C") is measured. Where only one "C" is measured, "T" is the time in minutes that it takes for water to move from the point of disinfectant application to a point before or at the point where residual disinfectant concentration ("C") is measured. Where more than one "C" is measured, "T" is (1) for the first measurement of "C", the time in minutes that it takes for water to move from the first or only point of disinfectant application to a point before or at the point where the first "C" is measured, and (2) for subsequent measurements of "C", the time in minutes that it takes for water to move from the previous "C" measurement point to the "C" measurement point for which the particular "T" is being calculated. Disinfectant contact time in pipelines shall be calculated based on "plug flow" by dividing the internal volume of the pipe by the maximum hourly flow rate through that pipe. Disinfectant contact time within mixing basins and storage reservoirs shall be determined by tracer studies or an equivalent demonstration. "Disinfection" means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents. "Disinfection profile" means a summary of daily Giardia lamblia inactivation through the treatment plant. "Domestic or other non-distribution system plumbing problem" means a coliform contamination problem in a public water system with more than one service connection that is limited to the specific service connection from which the coliform-positive sample was taken. "Dose equivalent" means the product of the absorbed dose from ionizing radiation and such factors as account for differences in biological effectiveness due to the type of radiation and its distribution in the body as specified by the International Commission on Radiological Units and Measurements (ICRU). "Dual sample set" is a set of two samples collected at the same time and same location, with one sample analyzed for TTHM and the other sample analyzed 20-8 3376
