Murphy, District 5 County Commission Meeting July 19, 2017 Agenda Item Number: M.7 Agenda Item Summary #3174 BULK ITEM: Yes DEPARTMENT: Sustainability TIME APPROXIMATE: STAFF CONTACT: Rhonda Haag (305) 453 -8774 N/A AGENDA ITEM WORDING: Approval of a $1.4 Million TMDL Stormwater Grant Application for a combined roads /canal restoration project in the Key Largo Twin Lakes Subdivision area, seeking $710,00,000 of grant funds towards a canal restoration project to install submerged culverts to improve dissolved oxygen impairments on canal #47 (Poor Ranked Canal) and the implementation of stormwater best management practices (BMP) infrastructure for the roads project, and offering $710,000 in budgeted roads funds as a match, retroactively ratifying the grant application submitted June 30, 2017; and authorization for the County Administrator to sign all necessary documents in connection with this grant. ITEM BACKGROUND: This is a Florida Department of Environmental Protection (DEP) Total Maximum Daily Load (TMDL) Grant Application combining an existing roads elevation project for Shaw Drive in Key Largo, with a new canal restoration project on canal 47 in the same neighborhood. The County has $200,000 in budgeted funds in FY18 for the design of the Twin Lakes Subdivision road elevation project in Key Largo, which includes a storm water management element. An additional $510,000+ is anticipated to be budgeted in FYI for the construction of the roads project. These $710,000 in funds will be used as a cash match to apply for $710,000 in additional funds for a new canal restoration project in Twin Lakes to improve the water quality in a poor rated canal and to partially fund some of the road storm water infrastructure work. The total grant amount is $1.4 Million. The grant requires a 50% match. To qualify for the TMDL grants, storm water management must be included. Therefore, a new canal restoration project was combined with the Twin Lakes road project to leverage the County's $710,000 budgeted project road funds to seek $710,000 in additional funds for a canal restoration project and stormwater infrastructure. The Canal on Twin Lakes is Poor and requires a restoration project to improve the water. This project is unique in nature as it combines two strategic programs (roads and canals) in protecting infrastructure and improving the impaired waters while incorporating conventional best management practices (BMP) for treating urban runoff prior to entering the canal and ultimately the Outstanding Florida Waters within the Florida Keys. The grant application was submitted June 30, 2017, with a deadline of July 6, 2017. The canal project includes strategic submerged culverts within the canal to provide additional treatment capabilities in improving the dissolved oxygen impairment within the waterbody.

This project is unique in nature as it combines various strategic programs in protecting infrastructure and improving the impaired waters while incorporating conventional BMP treatment practices for treating urban runoff prior to entering the canal and ultimately the Outstanding Florida Waters within the Florida Keys. The project also includes strategic submerged culverts within the canal to provide additional treatment capabilities in improving the dissolved oxygen impairment within the waterbody. Monroe County has been an integral partner in the Water Quality Protection Program Steering Committee since the inception in the early 90s who mission is to manage all waters as well as natural and cultural resources surrounding the Florida Keys. This committee along with the Monroe County Board of County Commissioners is committed to initiating water quality programs to preserve and protect the Outstanding Florida Waters within the Florida Keys. As an example, the County recently undertook a $1 billion septic to sewer program as well as another $7 million canal demonstration program to tackle the water quality impairment addressed within the Florida Keys Reasonable Assurance Plan. This is an important water quality restoration project that will enhance the nearshore waters of the Outstanding Florida Waterbody within the Florida Keys. This project is being partial funded by the local gas tax and will be used as an example tc obtain additional state and federal funds for water quality restoration projects throughout the Florida Keys. Monroe County will support this water quality restoration project using existing resources to the extent available. Rhonda Haag, Haag - Rhonda @monroecounty - fl.gov. telephone (305) 453 -8774 will be Monroe's main contact for this grant. We hope you consider this application favorable and support Monroe County's mission in continuing to improve the nearshore waters c the Outstanding Florida Waterbody within the Florida Keys. Please advise if there is any additional information needed to review this important time sensitive project. P Oman Ga stes . -DUnt?

MONITORING TO DETERMINE TREATMENT EFFECTIVENESS If this project is approved for funding, the applicant will be required to monitor CL the effectiveness of the stormwater BMP. BMP effectiveness data is required to demonstrate the environmental benefits of a project. The general monitoring requirements are set forth below. Please note that the final scope of work in the contract may include more specifics on particular monitoring requirements. Within six months before the completion of the project, the applicant will submit a detailed monitoring plan to the department for review and comment. The monitoring plan will specify the sampling locations, sampling instruments, and parameters to be sampled. The monitoring will include sampling of from seven to ten (10) storm events as described below. If possible, monitored events will be discrete rainfall events generally consisting of greater than 0.20 inches and less than 1.5 inches or rain. However, we want to monitor the real world to determine true efficiency. Therefore, remember this is a GENERAL guideline with respect to the storm event. Actual rainfall may vary depending on the type of BMP, the contributing drainage area, the amount of impervious area, and the time of concentration. Monitoring will be conducted at two locations: inflows and outflows. Monitoring will include the following parameters: • Daily rainfall (to nearest 0.01 inch) measured at the sampling location with verification from the local weather station. Rainfall data should be provided for at least the week proceeding monitoring and day(s) of monitoring. • Flow using approved flow activated flow meters • Parameters as specified below Parameter Detection Limit Method Total Cadmium 1 ug /I Composite* Total Chromium 5 ug /I Composite* Total Copper 5 ug /I Composite* Total Zinc 10 ug /I Composite* NO2 +NO3 0.1 mg /I Composite* TKN 0.3 mg /I Composite* Total Ammonia 0.05 mg /I Composite* Or Total N Composite* Total Phosphorus 0.05 mg /I Composite* Ortho Phosphate 0.05 mg /I Composite* TSS 1 mg /I Composite* Oil /Grease 1 mg /I Composite* Fecal coliform N/A Grab ** if possible 7 FORM #: 62- 305.900 RULE #: 62- 305.300(1) FORM TITLE: TMDL WATER QUALITY GRANT APPLICATION *Flow weighted composite samples will be taken over the storm hydrograph. Typically, the samples will be composited over the inflow hydrograph at the inflow and for up to a 36 hour period at outflow station, depending upon the time of concentration and flow into and out of the BMP. Each composite will include at least six evenly distributed sub - samples. * *Grab samples to be collected within the drainage area time of concentration at influent and effluent stations described above. The applicant should estimate the pollutant removal efficiency of the stormwater BMP by calculating the percent reduction in the event mean concentration (EMC) for the period of record [1- (Average Inflow EMC /Average Outflow EMC)]. For BMPs with multiple inflow (and /or outflow) points, the pollutant contributions for each inflow should be flow weighted. See the National Stormwater Best Management Practice database at http: / /www.bmpdatabase.orc/ and Development of Performance Measures, Determining Urban Stormwater Best Management Practice Removal Efficiencies, 1999 by URS Greiner Woodward Clyde, ASCE and EPA at http : / /www.bmpdatabase.org /task3 1.pdf From ASCE Data base 3.1 Efficiency Ratio Definition The efficiency ratio is defined in terms of the average event mean concentration (EMC) of pollutants over some time period: Average outlet EMC average inlet EMC — average outlet EMC ER= 1 - ----------------------- - - - - -- = ------------------------------------------------------- Average inlet EMC average inlet EMC EMCs can be either collected as flow weighted composite samples in the field or calculated from discrete measurements. The EMC for an individual event or set of field measurements, where discrete samples have been collected, is defined as: EMC= yViCilyVi where, V: volume of flow during period i C: average concentration associated with period i n: total number of measurements taken during event The arithmetic average EMC is defined as, averageEMC = EMCj l m where, m: number of events measured In addition, the log mean EMC can be calculated using the logarithmic transformation of each EMC. This transformation allows for normalization of the data for statistical purposes. CL E:3 FORM #: 62- 305.900 RULE #: 62- 305.300(1) FORM TITLE: TMDL WATER QUALITY GRANT APPLICATION Mean of the Log EMCs = Log(EMQ) / m 1 Estimates of the arithmetic summary statistics of the population (mean, median, standard deviation, and coefficient of variation) should be based on their theoretical relationships (Appendix A) with the mean and standard deviation of the transformed data. Computing the mean and standard deviation of log transforms of the sample EMC data and then converting them to an arithmetic estimate often obtains a better estimate of the mean of the population due to the more typical distributional characteristics of water quality data. This value will not match that produced by the simple arithmetic average of the data. Both provide an estimate of the population mean, but the approach utilizing the log- transformed data tends to provide a better estimator, as it has been shown in various investigations that pollutant, contaminant and constituent concentration levels have a log- normal distribution (NURP, 1983). As the sample size increases, the two values converge. eft Assumptions This method • Weights EMCs from all storms equally regardless of relative magnitude of storm. For example a high concentration /high volume event has equal weight in the average EMC as a low concentration /low volume event. The logarithmic approach tends to minimize the difference between the EMC and mass balance calculations. • Is most useful when loads are directly proportional to storm volume. For work conducted on nonpoint pollution (i.e., inflows), the EMC has been shown to not vary significantly with storm volume. This lends credence to using the average EMC value for the inflow but does not provide sufficient evidence that outflows are well represented by average EMC. Accuracy of this method will vary based on the BMP type. • Minimizes the impacts of smaller /cleaner storm events on actual performance calculations. For example, in a storm by storm efficiency approach, a low removal value for such an event is weighted equally to a larger value. • Allows for the use of data where portions of the inflow or outflow data are missing, based on the assumption that the inclusion of the missing data points would not significantly impact the calculated average EMC. Comments This method Is taken directly from nonpoint pollution studies and does a good job characterizing inflows to BMPs but fails to take into account some of the complexities of BMP design. For example, some BMPs may not have outflow EMCs that are normally distributed (e.g., a media filter that treats to a relatively constant level that is independent on inflow concentrations). Assumes that if all storms at the site had been monitored, the average inlet and outlet EMCs would be similar to those that were monitored. 10*] FORM #: 62- 305.900 RULE #: 62- 305.300(1) FORM TITLE: TMDL WATER QUALITY GRANT APPLICATION ATTACHMENT 3 - GRANT APPLICATION INSTRUCTIONS The DEP Bureau of Watershed Restoration administers state funds allocated to the TMDL program for the reduction of urban nonpoint source pollutant loadings to impaired waters.
