Hosted construction erosion control training for eight managers of CIP projects and City facilities construction. Exceeded Construction site Erosion and Sediment Control Enforcement Response Plan is developed and outlines process of periodic routine inspection, re-inspection for failed inspections, reinspection fee, Notice of Violation (NOV) and Stop Work Orders (SWO). Exceeded acreage is tracked in GIS layers for riparian buffers, water related habitat, upland habitat and floodplains. Page 22 of 96

23 MCM(s) Measurable Goal(s) Explain progress toward goal or how goal was achieved If goal was not accomplished please explain 4 Evaluate and Update Development Code and Drainage Criteria Manuals Not Met - Criteria manuals were updated in Drainage Criteria Manual update were completed in 2017 and taken to Public Utility Board and City Council for adoption in Changes in Development Code were proposed to consultant drafting code rewrites. 4 Track post construction BMP implementation 4, 6 Green Infrastructure and Low Impact Development tracking 4 Use of Integrated Stormwater Management (iswm) methods for stormwater construction 5 Document Illegal dumping and enforcement 5 Inspection of drainage infrastructure and operations 5 Track Municipal compost produced Met - Hickory Creek Watershed Protection Plan was adopted, outlines maintenance, inspection and regulation of post construction BMPs. Exceeded All alternative ESA plans are tracked. Excess parking is required to be permeable pavement and is tracked. LID infrastructure is tracked. City has adopted iswm. Exceeded Denton was designated an iswm Silver city. Water Quality volume as a design volume is codified and reviewed for all development requiring detention ponds (projects > 10 acres). Exceeded Watershed Protection, Community Improvement Services and Industrial Pretreatment logged all cased worked. Cases routed to Watershed Protection has 1005 resolution in Exceeded all drainage work orders are tracked in Cartegraph asset management software. Exceeded - Beneficial Reuse tracks the amount diverted from landfill and potentially illegally dumped. 5 Track pesticide applications Exceeded - All pesticide applications are tracked in compliance with TXG and integrated pest management procedures. Pesticide treatment areas are tracked in GIS. 5 Update Standard Operating Procedures (SOPs) and create SOPS for new methodologies Exceeded SOPs were updated for construction inspections, plan review, permit review, nitrates analysis and sonde calibration. New SOPs were developed for routine intern tasks. 5 Recycling program Exceeded curbside recycling was conducted and materials sorted at onsite MRF, bulky item pick up was offered, and both yard waste and household hazardous materials were picked up curbside for reuse. Fleet services recycled tires and oil. 5 Document training and number of visible spill response kits Exceeded - Hosted 13 MGH training events for City field staff which included spill response Page 23 of 96

24 MCM(s) Measurable Goal(s) Explain progress toward goal or how goal was achieved If goal was not accomplished please explain 5, 6 Update stormwater asset management database quarterly Exceeded GIS layers are maintained. Tech services migrated all environmental layers to a new server and improved transparency to the public by hosting more layers on the online interactive map portal. MSGP layer was updated to include designations for active/nec, permit not required and out of business. 5 Document street sweeping management program 6 Conduct Industrial permit audits and surveys 6 Industrial Pretreatment (IP) Program documentation of inspections and violations Exceeded Streets were swept and tracked with Cartegraph asset management software. Streets also responded to citizen calls and swept needed areas ahead of schedule. Exceeded - Surveys are required for certificate of occupancy issuance, applicable businesses are added to Linko database as wastewater or stormwater permitees as applicable and staff follows up with permit requirements. Exceeded - IP tracks all categorical and small generator wastewater users in Linko software. Sites are audited and samples collected with ISCO automated water samplers. Site audit includes MSGP stormwater inspection. Industrial stormwater database for MSGP inspections was migrated from Asist database to Linko to improve cross-departmental efficiency and enhance MSGP inspection capacity. MSGP inspections are entered into Linko software. C. Stormwater Data Summary Provide a summary of all information used including any lab results (if sampling was conducted) to assess the success of the SWMP at reducing the discharge of pollutants to the MEP. For example, did the MS4 conduct visual inspections, clean the inlets, look for illicit discharge, clean streets, look for flow during dry weather, etc.?

Problem abated. Stormwater discharge from TPDES MSGP (TXR05BB90) site: Stubbs Iron & Metal (Sector N, 5093) concern over plastic/metal debris discharging, and possible contamination killing grass. MSGP inspection found they were a year behind on stormwater monitoring (had reasons for each event, but it was stressed that they need to make it a priority to sample). Main BMP at outfall was found to be improperly installed and in need of maintenance (oil absorbent boom was deteriorating). Follow-up inspection found they had replaced BMP and made efforts to better manage SWPPP by hiring James Environmental Management Inc. (Round Rock, TX) to handle their MSGP. Benchmark sampling conducted 6/27/2017 and 12/15/2017, exceeded Benchmarks for multiple items. 2/21/2018 they were asked by city staff to investigate exceedances and determine necessary BMP changes. 4/3/ Market St Parking lot flooding at a location that historically had poor drainage, but a non-tpdes construction site's phase 1 BMPs exacerbated problems by limiting positive drainage. Staff had downstream controls removed (construction project stalled before cutting ground and then when inactive and eventually closed without disturbance).

Allowed them to continue draining pool (which was under repair). 11/30/2017 Interstate 35 E 2434 (Storm Sewer Vault) Storm sewer vault with FOG discharge. Restaurant issued warning to have grease trap pumped out. Restaurant complied. Discharge abated. 12/6/ N Bell Ave 12/6/2017 Oak Street East /7/ Silverdome, lot /8/ Jim Christal Rd 12/8/ S Mayhill Rd 12/12/ Stillhouse Hollow Ln Concern about possible water or sanitary sewer leak at property. Investigation found it to likely be groundwater (Chlorine <0.1mg/L, Iron <0.2mg/L). History of property infrastructure (french drains, etc.) confirms this spring has been going on for decades. Complaint of oil being dumped behind restaurant, investigation found no evidence of this. There is a waste oil container but no evidence of a spill. Sanitary Sewer Overflow at Woodhaven MHP, complaint that management was not responsive to the SSO. Site is in the ETJ. However, the private collection system does discharge into Denton's wastewater collection system so WW took over enforcement. Industrial site (non MSGP) was seen discharging an unknown liquid from their facility onto parking lot. Investigation found this to be boiler water condensate, which their claim was this was pure water. Samples were not able to be taken as the discharge halted by the time stormwater staff arrived on-site. Management told to plumb to sanitary sewer and not let this happen again; verbal warning. TPDES MSGP site (Opala, Inc. TXR05CM51) was found to have discharged wastewater from a containment unit that didn't have the appropriate secondary containment. Opala claimed it was due to a burst pipe in recent freeze but would not have happened if appropriately contained. Standing water discharge had a strong odor with ph 5.7 s.u.; 5-Day BOD >422.4 mg/l, confirming illicit discharge. Charges were pursued through police but city contract was instead severed with company and lease revoked. Discharge abated. TPDES construction site (TXR15YD97) left piles of debris on-site for many weeks. Complaint was filed and they were required to remove the debris. 12/13/ S Loop 288 Fish kill reported at retention pond at county administration building complex. The death was explainable by a recent deep freeze event, when it became clear that all the dead fish were Tilapia (a tropical fish not suited to cold environments). Page 66 of 96
