Safety Measures and Procedures Maintenance plans should include procedures and equipment required to protect the safety of inspection and maintenance personnel. Maintenance training begins with a basic description of the purpose and function of the overall stormwater management measure and its major components. Such understanding will enable maintenance personnel to provide more effective component maintenance and more readily detect maintenance-related problems. Depending on the size, character, location, and components of a stormwater management measure, maintenance personnel may also require training in specialized inspection and maintenance tasks and/or the operation and care of specialized maintenance equipment. Training should also be provided in the need for and use of all required safety equipment and procedures. Safety Regulations and Requirements The maintenance personnel/contractor to follow the safety protocols as is already regulated and standardized in the industry, including but not limited to the requirements of the following: - Occupational Safety & Health Act of 1970 - Administrative Procedures Act (APA) - National Environmental Policy Act (NEPA) - Regulatory Planning and Review (Executive Order 12866) Safety Tools, Equipment and Garments Safety Tools and Equipment Location Responsible Person/Contact # Subcontractor certified by OSHA to do work necessary for clean up.

This training must result in an understanding of the hazards in the permit space and the methods used to isolate, control or in other ways protect employees from these hazards, and for those employees not authorized to perform entry rescues, in the dangers of attempting such rescues Obtained by Subcontractor if needed. Personnel entering inlet to use safe confined space entry procedures OSHA Certified Subcontractor Safety Training OSHA Training Requirements, 1926.1207 Training (d) The employer must maintain training records to show that the training required by paragraphs 1926.1207(a) through (c) of this standard has been accomplished. The training records must contain each employee’s name, the name of the trainers, and the dates of training. The documentation must be available for inspection by employees and their authorized representatives, for the period of time the employee is employed by that employer. Safety Procedures To effectively control and prevent hazards, employers should:  Involve workers, who often have the best understanding of the conditions that create hazards and insights into how they can be controlled.  Identify and evaluate options for controlling hazards, using a "hierarchy of controls."

Stormwater Maintenance Plan for 525 Northfield Avenue, Lot 1.01, Block 159.04 Township of West Orange, Essex County, New Jersey Jarmel Kizel Project No. Gomesgr24-223 January 28, 2026  Use a hazard control plan to guide the selection and implementation of controls, and implement controls according to the plan.  Develop plans with measures to protect workers during emergencies and nonroutine activities.  Evaluate the effectiveness of existing controls to determine whether they continue to provide protection, or whether different controls may be more effective. Review new tech  nologies for their potential to be more protective, more reliable, or less costly. Emergency Procedures OSHA Training Requirements, 1910.146 Permit required confined spaces (k) Rescue and emergency services (1) An employer who designates rescue and emergency services, pursuant to paragraph (d)(9) of this section, shall: (i) Evaluate a prospective rescuer’s ability to respond to a rescue summons in a timely manner, considering the hazard(s) identified; Note to paragraph (k)(1)(i): What will be considered timely will vary according to the specific hazards involved in each entry. For example, §1910.134, Respiratory Protection, requires that employers provide a standby person or persons capable of immediate action to rescue employee(s) wearing respiratory protection while in work areas defined as IDLH atmospheres. (g) and (k)(1)(i) through (iv) 52 Training Requirements in OSHA Standards (ii) Evaluate a prospective rescue service’s ability, in terms of proficiency with rescue-related tasks and equipment, to function appropriately while rescuing entrants from the particular permit space or types of permit spaces identified; (iii) Select a rescue team or service from those evaluated that: (A) Has the capability to reach the victim(s) within a time frame that is appropriate for the permit space hazard(s) identified; (B) Is equipped for and proficient in performing the needed rescue services; (iv) Inform each rescue team or service of the hazards they may confront when called on to perform rescue at the site.

K. Annual Evaluation of the Effectiveness of the Plan The person responsible for maintenance shall evaluate the effectiveness of the maintenance plan at least once per year and adjust the plan and the deed as needed. The responsible party should evaluate the effectiveness of the maintenance plan by comparing the maintenance plan with the actual performance of the maintenance. The items to evaluate may include, but not limited to, - Whether the inspections have been performed as scheduled; - Whether the preventive maintenance has been performed as scheduled; - Whether the frequency of preventative maintenance needs to increase or decrease; - Whether the planned resources were enough to perform the maintenance; - Whether the repairs were completed on time; - Whether the actual cost was consistent with the estimated cost; - Whether the inspection, maintenance, and repair records have been kept. If actual performance of those items has been deviated from the maintenance plan, the party responsible should find the causes and implement solutions in a revised maintenance plan.

Part II- Field Manuals Preventative and corrective maintenance shall be performed to maintain the function of stormwater management measures, including repair or replacement of the structure; removal of sediment, debris or trash; restoration of eroded areas; snow and ice removal; fence repair or replacement; restoration of vegetation; repair or replacement of non-vegetated linings, and removal of rodent/wildlife and repair/restoration to damaged affected areas caused by them. 1. INLETS—In parking lots and driveways, rain (and melting snow) will travel across the ground as runoff to be collected into an underground piping system, by first dropping through metal grates into concrete boxes called inlets. The inlets have specially designed grates to prevent large pieces of debris and trash from getting into the inlet and pipes. All structures should be periodically inspected for debris and clean as needed. 2. PIPES—The runoff travels underground through the pipes to a point of discharge. These pipes are usually made of reinforced concrete (RCP), high density propylene (HDPP—usually black plastic), or polyvinyl chloride (PVC—usually white plastic). Most pipes are of solid wall construction to transport runoff water or to be used to temporarily detain water as part of the detention system. Other pipes may be perforated, which can be used to let water drain out through the holes into the surrounding ground or water from the ground can flow into the pipes depending on soils, ground conditions, elevations, and so forth. Pipes should be periodically inspected for debris and clean as needed. Also the pipe system should be flush periodically in order to keep the sediment from accumulating inside the pipes. 3. GUTTERS/DOWNSPOUTS/SPLASH PADS—Under state and local stormwater regulations, runoff water flowing off of roofs is considered “clean” and does not necessarily have to be directed to the stormwater system which maybe basins, ponds, drywells, underground pipes and so forth. In general, allowing the water to flow through areas of dense vegetation (woodlands, meadows, and so forth, but not basic lawn areas) is sufficient to clean the water even further. In order for the water to flow clean, the system should be maintain clean.

PART III—Gutters and Leaders As part of good maintenance procedure, it is recommended that the gutters and leaders be periodically inspected and cleaned. The building drainage system should particularly be inspected during the autumn when falling and blowing leaves and miscellaneous materials can easily clog drain pipes, plug downspouts, and cover inlet grates. Gutters and leaders should also be inspected in the springtime for debris, correct pitch, loose connections, and other various problems that may have occurred over the winter. It is also suggested that the system be examined whenever large storms are predicted. Debris removed from the drainage system should be examined for reuse. That is, it can be separated into trash, recyclables, and organic matter. Organic materials such as leaves and twigs could possibly be composted if there is sufficient room at the site for such activity. Equipment for gutter and leader cleaning could include ladders, “grab” poles, rakes, plumber’s snakes, and garden hoses. Heavy duty rubber or leather work gloves, non- slip work shoes, and protective eyewear are also recommended. PART IV—Inlets Inlets and discharge control devices should be inspected after several storms to ensure that they are functioning properly and that there is no erosion or debris problems developing. Source of sediment contamination should be identified and controlled when native soil is exposed or erosion channels are present. Inspect for sediment and debris buildup. Sediment buildup exceeding 2 inches in depth or that begins to constrict the flow path should be removed. The Inlet control devices should particularly be inspected during the autumn when falling and blowing leaves and miscellaneous materials can easily clog drain pipes, plug downspouts, and cover inlet grates. Clean out leaves, trash, debris, etc. Maintain records of all inspections and maintenance activity. Include estimate of sediment and/or debris removed. Indicate sediment and/or debris disposal methods.
