- Category: RECD & Emission Control Devices
Many Indian sites no longer run their own generators. A facility management company handles a tech park’s DG sets, an AMC vendor looks after a hospital’s standby fleet, and a telecom operator pays an O&M partner to keep remote sites running. Outsourcing makes sense: specialist contractors have trained staff, spares and on-call technicians that most owners cannot justify in-house.
When a Retrofit Emission Control Device is added, though, a quiet question appears. The contractor runs the generator, so does the contractor own the RECD’s performance? If the device clogs, an alarm is ignored or the records are missing during an inspection, who answers for it?
The practical answer is that the work can be outsourced, but the accountability usually cannot. Under most consents and registrations, legal responsibility for compliance typically stays with the owner or occupier named on the document. The contractor is responsible for what the contract says it must do. If the contract is silent on RECD duties, those duties may fall between the two parties and nobody does them. This post gives you two tools to close that gap: a RACI matrix that splits RECD tasks between the parties, and a clause-by-clause guide for writing those duties into your O&M or AMC contract.
This is practical guidance, not legal advice. Always check the wording of your consent, registration and contract, and take legal advice where liability is in question.
Responsibility Versus Accountability
RACI separates four roles, and the distinction matters here.
- Responsible (R): does the work.
- Accountable (A): owns the outcome and signs off. There should be only one A per task.
- Consulted (C): gives input before or during the work.
- Informed (I): is told the result.
In an outsourced DG operation, the contractor is Responsible for most hands-on tasks. The owner is typically Accountable for compliance outcomes, because the consent is in the owner’s name and the State Pollution Control Board will normally deal with the consent holder. Good contracts make the contractor Accountable for the quality and timeliness of its own work (a log entry made on time, a cleaning done to the procedure), while the owner stays Accountable for the overall compliance position.
The Five Parties
The owner or occupier
The entity named on the consent or registration. It decides the budget, approves contracts and answers to the regulator. In a leased building this may be the landlord or a tenant; our post on managing RECD projects in buildings with several equipment owners covers that complication.
The O&M or AMC contractor
Runs the generator day to day: starts, stops, checks, logs, routine maintenance and first response to faults. It may or may not have been trained on the RECD. Our guide to in-house maintenance vs AMC for generators explains the wider trade-offs.
The RECD supplier
Designed and supplied the device, trained the site team at handover and provides spares, specialist cleaning and warranty support. It does not usually operate the generator.
The BMS contractor
Where RECD signals feed a building management system, this contractor owns the integration: points, alarms, screens and data retention. See integrating RECD monitoring with a building management system.
The testing laboratory
Carries out emission tests when required, such as at commissioning, after major changes or as the consent demands. Usually engaged by the owner, sometimes through the contractor.
The RECD RACI Matrix
The matrix below is a worked, illustrative split for a typical outsourced site. Adjust it to your contract, consent and the supplier’s manual. O = owner, M = O&M or AMC contractor, S = RECD supplier, B = BMS contractor, L = testing laboratory.
| # | Task | O | M | S | B | L |
|---|---|---|---|---|---|---|
| 1 | Keep consent, registration and RECD certificates current | A/R | I | C | ||
| 2 | Daily visual checks of RECD, joints, supports and controller | I | A/R | C | ||
| 3 | Record back-pressure and temperature in the daily or run log | I | A/R | C | C | |
| 4 | Respond to RECD alarms within agreed time | I | A/R | C | C | |
| 5 | Decide whether to keep running with an active RECD alarm | A | R | C | ||
| 6 | Support regeneration (load management, run duration, operating mode) per manual | I | A/R | C | ||
| 7 | Routine cleaning of the filter or ash removal | I | A | R | ||
| 8 | Calibrate or verify pressure and temperature sensors | I | A | R | C | |
| 9 | Maintain BMS points, alarms and data storage for RECD signals | I | C | C | A/R | |
| 10 | Keep event logs and maintenance records in the agreed format | A | R | C | C | |
| 11 | Arrange and witness periodic emission tests | A | R | C | R | |
| 12 | Train new operators on RECD checks and alarm response | A | R | R | ||
| 13 | Order and hold RECD spares | A | R | C | ||
| 14 | Report RECD performance monthly (KPIs) | A | R | I | C | |
| 15 | Hand over RECD records and status when contractors change | A | R | C | C |
How to read the matrix
A few rows need explanation.
Row 5 is the most important. Deciding whether to keep a generator running when the RECD shows a high back-pressure alarm is a judgement between compliance, continuity and engine protection. The contractor is on site and must act, but the owner should set the rules in advance and remain Accountable. Write a decision rule into the contract and an RECD alarm response matrix for operators so the technician at 2 a.m. knows what to do. Engine-protection decisions should follow the DG maintainer’s and engine maker’s guidance. The difference between an alarm and a trip is covered in RECD alarm vs generator trip control response.
Row 7 places the contractor as Accountable but the supplier as Responsible. Many sites prefer the RECD supplier to do specialist cleaning, with the AMC contractor arranging access, shutting down the set and confirming completion. If your contractor is trained and equipped to clean, swap the R.
Row 8 matters more than it looks. A drifting pressure sensor can hide a clogging filter or trigger false alarms. Calibration records also form part of the evidence an inspector may ask for. See installed RECD sensor calibration documentation.
Row 10 keeps the owner Accountable because the records support the owner’s compliance position. The contractor writes them; the owner checks them.
Contract Clause Guide
The matrix only works if the contract backs it up. Below are the clauses that most often need adding or tightening when an RECD is introduced. Use them as a checklist for your lawyer or procurement team, not as ready legal wording.
Clause 1: Scope of work
State plainly that the RECD, its controller, sensors and connecting exhaust sections are within the contractor’s scope. Many AMC contracts list “DG set and accessories” and both sides later argue about whether a retrofitted device counts. Attach the supplier’s operation and maintenance manual as a contract document, and name which tasks from it the contractor performs and which it arranges through the supplier.
Clause 2: Daily checks and log format
Specify the checks, the frequency and the log format. Include at least: run start and stop times, load, back-pressure, exhaust temperature, alarm status and remarks. Ask for times in a consistent format (ISO 8601 style dates help when logs are merged later) and for the generator and RECD logs to use the same clock. Our guides on what to record in an RECD event log and aligning RECD sensor timestamps with generator runtime logs explain why.
Clause 3: Alarm response
Set response times by alarm priority, for example: acknowledge on site within 15 minutes for a high-priority alarm during a run, inform the owner’s nominated person within 30 minutes, and record the action taken. Refer to the site alarm response matrix. Good alarm practice, such as that described in the ANSI overview of ISA-18.2 alarm management, is a sensible model: every alarm should have a defined response and a named owner.
Clause 4: Regeneration support
RECDs depend on operating conditions. If the supplier’s manual asks for particular load levels, run durations or regeneration procedures, the contractor must follow them and record when it did. If load conditions are outside the contractor’s control (for example, the building simply does not draw enough load), the contract should require the contractor to report it rather than quietly accept it. See choosing an RECD for a generator running at low load.
Clause 5: Cleaning, calibration and spares
Name who cleans, who calibrates and at what intervals, who holds spares and who pays. If the supplier performs these tasks under a separate agreement, the AMC contract should require the contractor to schedule and witness them. Align the intervals with the RECD maintenance guide and the supplier’s manual.
Clause 6: KPIs and SLAs
Measurable targets turn good intentions into something you can manage. A starter set is shown below; the targets are illustrative, so set your own from the supplier’s manual and your site’s risk.
| KPI | How measured | Illustrative target |
|---|---|---|
| Daily check completion | Completed checks ÷ scheduled checks | 98% or higher per month |
| Log completeness | Run events with all required fields ÷ total run events | 100% |
| Alarm acknowledgement time | Time from alarm to recorded acknowledgement | Within 15 minutes, high priority |
| Alarm closure with recorded action | Alarms with documented cause and action ÷ total alarms | 95% or higher |
| Cleaning done on schedule | Cleanings within ±7 days of due date ÷ due cleanings | 100% |
| Sensor verification on schedule | Verifications completed by due date ÷ due | 100% |
| Monthly report delivered | Report received by agreed day | By the 5th of each month |
| Back-pressure excursions reported | Excursions reported to owner within 24 hours ÷ excursions | 100% |
Link a small part of the contractor’s fee, or a service credit, to these KPIs. Keep it proportionate: the aim is attention, not a fight over penalties.
Clause 7: Records and data ownership
State that all logs, reports, photos and controller or BMS data relating to the RECD belong to the owner, must be kept for an agreed period and must be handed over on request and at contract end. Specify the format (spreadsheet, PDF, raw export) and where the master copy lives. The NIST SP 800-92 guide to log management is written for IT systems but its principles of retention, integrity and review apply well to operational logs.
Clause 8: Training and staff changes
Require that every operator who runs the set has been trained on RECD checks and alarm response, and that new staff are trained before working alone. Ask for a training register. See operator training in the RECD purchase order.
Clause 9: Audit rights
Give the owner the right to inspect logs, observe checks, review alarm histories and visit at short notice. Include the right to appoint a third party, such as the RECD supplier, to carry out a technical audit. More on this below.
Clause 10: Change notification
Require the contractor to inform the owner before changes that might affect RECD performance: engine overhauls, exhaust modifications, controller setting changes, or a change in duty. These can mean the device needs review or retesting, as explained in when to retest an RECD after DG set changes.
Clause 11: Liability and cooperation
Contracts often allocate the cost of fines or damage caused by the contractor’s negligence. Whether such a clause is enforceable, and how it interacts with the consent holder’s duties, is a legal question for your adviser. What you can always include is a cooperation duty: the contractor must support the owner during inspections, provide records within an agreed time and make trained staff available.
Handover Between Contractors
The riskiest moment in an outsourced operation is when one contractor leaves and another arrives. Knowledge walks out of the gate, logs go missing and the new team may not even know an RECD needs routine attention. Build a handover protocol into both the outgoing and incoming contracts.
The outgoing contractor should hand over:
- Complete logs for the contract period, in the agreed format.
- The alarm history and any open faults.
- Cleaning and calibration records, with due dates for the next ones.
- Spares inventory and location.
- Controller settings, if the site records them (see RECD controller settings access control).
- A short written status note signed by its site lead.
The incoming contractor should complete, before taking over alone:
- A joint walk-down of each set and RECD with the outgoing contractor and the owner.
- Training of its operators, ideally with the RECD supplier present.
- Confirmation that it has access to the controller, BMS screens and log templates.
- A first-week report confirming baseline back-pressure readings at known loads.
The owner should hold back final payment to the outgoing contractor until the records are handed over complete. This is the single most effective lever available.
Audit Rights in Practice
Audit rights are only useful if you use them. A light routine is enough for most sites.
- Monthly: review the KPI report and spot-check five random log entries against controller or BMS data.
- Quarterly: observe a daily check being done; review the alarm list for repeated or unresolved alarms.
- Annually: ask the RECD supplier or an independent engineer to review condition, records and calibration status.
Keep audit findings in a short register with actions and dates. If an inspector asks how you oversee your contractor, this register is your answer. Our environmental compliance checklist for generator owners can be used as the audit framework.
Common Gaps
These are the patterns that most often leave RECD duties unowned.
- The RECD is not mentioned in the AMC at all. The contract predates the retrofit and was never amended.
- Cleaning is “by supplier” but nobody schedules it. The supplier waits to be called; the contractor assumes the supplier will come.
- Logs record the engine but not the RECD. Back-pressure and alarm status are missing from the log sheet.
- BMS alarms go to an unmonitored screen. The integration exists but nobody is assigned to watch it out of hours.
- Training happened once. The operators trained at commissioning have since moved on.
- Records live with the contractor. When the contract ends, so does access to the history.
- No decision rule for running with an alarm. The technician guesses, either shutting down unnecessarily or running on with a blocked filter.
Scenario: How a Gap Became a Problem (Illustrative)
The following scenario is illustrative, combining issues seen across many sites rather than describing a real one.
A corporate office in Gurugram has two 500 kVA DG sets fitted with RECDs. The owner changed AMC contractors in July. The outgoing contractor’s log sheets included back-pressure readings; the new contractor used its own standard template, which did not. Cleaning was listed in the supplier’s manual, but the new AMC contract said only “maintenance of DG sets as per OEM schedule”. Nobody added the RECD.
In November, with GRAP restrictions in force and grid outages common, both sets ran more than usual at light load. Back-pressure rose. The RECD controller raised a high back-pressure alarm on DG-2, which was shown on a BMS screen in the security cabin. Security staff assumed it was an engineering matter and did not escalate. The AMC technician, unaware of the alarm because his template did not ask for it, kept the set running.
Two weeks later the engine showed signs of strain under load and the AMC contractor called the owner. The RECD supplier found a heavily loaded filter that had missed its cleaning date by six weeks. The same week, an SPCB inspection asked for maintenance records for the RECDs. The owner could produce the commissioning report but nothing for the past four months.
What would have prevented it:
- A handover protocol requiring the incoming contractor to adopt the existing log format.
- An AMC scope clause naming the RECD and attaching the supplier’s manual.
- A RACI row for cleaning, with the contractor Accountable for scheduling.
- A named person responsible for BMS RECD alarms out of hours.
- A monthly KPI report showing log completeness and cleaning status, which would have flagged the gap in August.
None of these needed new equipment. They needed a few lines in a contract and a one-page RACI.
Frequently Asked Questions
Can I transfer legal responsibility for RECD compliance to my AMC contractor?
Typically not in full. The consent or registration is in the owner’s or occupier’s name, and the regulator will normally deal with that party. A contract can make the contractor responsible to you for its own work and may allocate costs between you, but check your consent and take legal advice before relying on any transfer.
Should the RECD supplier or the AMC contractor clean the device?
Either can work. What matters is that one party is named as Responsible and one as Accountable for scheduling. Many owners choose the supplier for specialist cleaning and the contractor for coordination.
What should the monthly contractor report include?
Run hours per set, load profile summary, back-pressure trends at comparable loads, alarms and actions, cleaning and calibration status, open faults and KPI results. A simple RECD operating dashboard can generate much of this automatically if your monitoring supports it.
Does a short-term rental set change any of this?
The same principles apply, but check who holds the consent for the rental set, whose contractor maintains it, and whether the rental agreement says who looks after the RECD during the hire period.
How do I add RECD duties to an existing AMC mid-term?
Issue a contract amendment listing the new tasks, the RACI, the log format and any change in fee. Most contractors will accept a reasonable addition if it is clearly defined. For negotiation tips, see how to negotiate an AMC contract for your generator.
