Trinity River Authority ofTexas Northern Region Office 3110.800/July 14, 2005 Ms. Nancy Cline Director of Public Works Town of Addison P.O. Box 9010 Addison, Texas 75001-9010 RE: Central
Regional Wastewater System FY 2005 Mid-Year Reallocation Revised Monthly Billing Dear Ms. Cline: In the planning. and development efforts for establishing each contributing party's proportionate
share of the Central Regional Wastewater System annual operation, maintenance and debt service costs for Fiscal Year 2005, each city's wastewater flow volumes were estimated on the basis
of historical flows, city projections and Authority management's judgment. The System obligation was distributed among all of the contracting parties on the basis of a percentage obtained
by dividing each party's predicted annual contributing flow by the total estimated System flow, times the proposed annual budget requirement. At mid-year, actual metered flow data has
become available necessitating an evaluation and aqjustment. of each contracting party's flows and monthly payment obligations. Based upon a review of the year-to-date metered flows
this fiscal year and actual flows over the past twelve months, the monthly billings have been re-detennined for the last four months of FY 2005 to reflect changes in the predicted obligation
for all contracting parties. The adjustment for the Town of Addison is attached, reflecting that the monthly billing will change from $70,040 to $78,515. The above revised amount will
be billed to your city monthly beginning with the August billing to be mailed during July. At the end of the fiscal year, the difference between the reallocated obligation and the actual
obligation will be detennined and the Authority will submit the variance as a credit or debit. If you have any questions conceming the mid-year reallocation, please contact this office.

Central Regional Wastewater System FY 2004 Mid-Year Reallocation Revised Monthly Billing Dear Mr. Murphy: In the planning and development efforts for establishing each contributing party's
proportionate share of the Central Regional Wastewater System annual operation, maintenance and debt service costs for Fiscal Year 2004, each city's wastewater flow volumes were estimated
on the basis of historical flows, city projections and Authority management's judgment. The System obligation was distributed among all of the contracting parties on the basis of a percentage
obtained by dividing each party's predicted annual contributing flow by the total estimated System flow, times the proposed annual budget requirement. At mid-year, actual metered flow
data has become available necessitating an evaluation and adjustment of each contracting party's flows and monthly payment obligations. Based upon a review of the year-to-date metered
flows this fiscal year and actual flows over the past twelve months, the monthly billings have been re-determined for the last four months of FY 2004 to reflect changes in the predicted
obligation for all contracting parties. The adjustment for the Town of Addison is attached, reflecting that the monthly billing will change from $69,360 to $73,776. The above revised
amount will be billed to your city monthly beginning with the August billing to be mailed during July. At the end of the fiscal year, the difference between the reallocated obligation
and the actual obligation will be detenmined and the Authority will submit the variance as a credit or debit. If you have any questions conceming the mid-year reallocation, please contact
this office. 􀁾.. Jlt { 􀁾􀁔􀁐􀀭􀀧􀁒􀁾􀁉􀁃􀁉􀁁􀀠M. CLEVELAND Manager, Operations Encl c: Danny F. Vance, General Manager Warren N. Brewer, Regional Manager, Northern Region John M. Nelson,

Central Regional Wastewater System FY 2003 "Settle Up" Dear Mr. Murphy: In accordance with the terms of the Contract for Wastewater Services, each of the contracting parties in the Central
Regional Wastewater System (CRWS) is obligated to pay a share of the annual System costs based on its proportionate share of the total wastewater flow contribution to the System during
the fiscal year. For the period of December 1, 2002 through November 30, 2003, an independent audit was performed to establish actual expenditures during the fiscal year and a determination
was made as to each contracting party's proportionate share of said expenditures. Additionally, since 199B the Authority, with the approval of the CRWS Advisory Committee, has adjusted
the flow contribution to allocate System 1&1 as determined through an engineering study performed by Black and Veatch Corporation. Each party's annual obligation is compared to the actual
collections from that party and, if a variance eXists, a refund check or a final invoice is issued to close out the fiscal year. The enclosed Central Regional Wastewater System FY 2003
Schedule of Actual AnnualRequirement and Ending Accounts Receivable/{Payable} summarizes the year-end status of each party, including the 1/1 adjustment. The Town of Addison ended the year with a credit balance
of $2B,033 for which a check is enclosed. If you should have any questions concerning the FY 2003 "Settle Up", please give me a call. iffcerdy, vh-01U I RICIA M. CLEVELAN'D Manager,

Central Regional Wastewater System FY 2003 Mid-Year Reallocation Revised Monthly Billing Dear Mr. Murphy: In the planning and development efforts for establishing each contributing party's
proportionate share of the Central Regional Wastewater System annual operation, maintenance and debt service costs for Fiscal Year 2003, each city's wastewater flow volumes were estimated
on the basis of historical flows, city projections and Authority management's judgement. The System obligation was distributed among all of the contracting parties on the basis of a
percentage obtained by dividing each party's predicted annual contributing flow by the total estimated System flow, times the proposed annual budget requirement. At mid-year, actual
metered flow data has become available necessitating an evaluation and adjustment of each contracting party's flows and monthly payment obligations. Based upon a review of the year -to-date
metered flows this fiscal year and actual flows over the past twelve months, the monthly billings have been re-determined for the last four months of FY 2003 to reflect changes in the
predicted obligation for all contracting parties. The adjustment for the Town of Addison is attached, reflecting that the monthly billing will change from $69,087 to $61,986. ,. The
above revised amount will be billed to your city monthly beginning with the August billing to be mailed during early August. At the end of the fiscal year, the difference between the
reallocated obligation and the actual obligation will be determined and the Authority will submit the variance as a credit or debit. If you have any questions concerning the mid-year
reallocation, please contact this office. 􀀨􀀱􀁣􀁾􀀠WJ)􀁾􀁍􀀮􀁾􀁅􀁾􀁅􀁌􀁁􀁎􀁄􀀠Manager, Operations Encl c: Danny F. Vance, General Manager Warren N. Brewer, Regional Manager, Northern

Mr. Murphy: Re: Central Regional Wastewater System FY 2001 "Settle Up" In accordance with the terms of the Contract for Wastewater Services, each of the contracting parties in the Central
Regional Wastewater System (CRWS) is obligated to pay a share of the annual System costs based on its proportionate share of the total wastewater flow contribution to the System during
the fiscal year. For the period of December 1, 2000 through November 30, 2001, an independent audit was performed to establish actual expenditures during the fiscal year and a determination
was made as to each contracting party's proportionate share of said expenditures. Additionally, since 1998 the Authority, with the approval of the CRWS Advisory Committee, has adjusted
the flow contribution to allocate System 1&1 as determined through an engineering study performed by Black and Veatch Corporation. Each party's annual obligation is compared to the actual
collections from that party and, if a variance exists, a refund check or a final invoice is issued to close out the fiscal year. The enclosed Central Regional Wastewater System FY 2001
Schedule of Actual Annual Requirement and Ending Accounts Receivable/(Payable) summarizes the year-end status of each party, including the 1/1 adjustment. The Town of Addison ended the
year with a credit balance of $13,444 for which a check is enclosed. If you should have any questions conceming the FY 2001 "Settle Up", please give me a call. "elY, 􀁬􀁤􀁲􀁾􀁌􀁍􀁌􀁁􀁎􀁾􀀠Manager,

Billing In the planning and development efforts for establishing each contributing party's proportionate share of the Central Regional Wastewater System annual operation, maintenance
and debt service costs for Fiscal Year 2001, each city's wastewater flow volumes were estimated on the basis of historical flows, city projections and AuthOrity management's judgement.
The System obligation was distributed among all of the contracting parties on the basis of a percentage obtained by dividing each parties predicted annual contributing flow by the lotal
estimated System flow, times the proposed annual budget requirement. At mid-year, actual power expenses and metered flow data have become available necessitating an evaluation and adjustment
of each contracting party's flows and monthly payment obligations. The Authority has estimated that the FY 2001 power expenses will be $5,100,000, which is $1,600,000 more than the budgeted
power expenditures due to increases in TXU fuel charges and surcharges, as well as attributed to 11% higher flow contributions than originally planned during the months of January through
April this fiscal year. Based upon a review of the year-to-date metered flows this fiscal year and actual flows over the past twelve months, the monthly billings have been re-determined
for the next five months of FY 2001 to reflect changes in the predicted obligation for all contracting parties. The adjustment for the Town of Addison is attached, reflecting that the
monthly billing will change from $69,303 to $70,784. The above revised amount will be bjlled tgyour city monthly beginnil1g 􀁾􀁩􀁴􀁨􀀠the July billing. tQbe .mailed , during the month
