Introductory note
This introductory note does not form a part of the permit
A non-technical description of the installation is given in the Application, but the main features of theinstallation are as follows.
Barking Power Station is an electricity generating station, located at Chequers Lane, Dagenham,Essex and operated by Thames Power Services.
The installation is located within an area of primarily industrial and commercial use adjacent toDagenham Dock. It is located between Chequers Lane (to the west) and the Dagenham Breach (tothe east), approximately 1 km north of the River Thames, centred at National Grid Reference TQ490 824 (549090 182400). The installation is solely owned by Barking Power Limited and wasdeveloped for use as a power station between 1992 and 1995. The installation occupies a land areaof approximately 15 ha (37 acres).
The Barking Power Station comprises 5 gas turbines, with a combined thermal input of 2125MW, 2steam turbines and all of the ancillary equipment required for the generation of electricity for exportto the national grid.
It utilises modern gas turbines fuelled with natural gas to produce electricity. The generating stationhas a nominal capacity to produce 1000MW of electricity and is connected to the National Gridelectricity transmission system. The station operates mainly as a continuous base load plant, but itcan operate at different loads.
The power station has two CCGT modules or power blocks, capable of operating independently.Block 1 produces 400MW of electricity and Block 2 produces 600MW. Block 1 comprises two gasturbines and one steam turbine; Block 2 comprises three gas turbines and one steam turbine. Bothblocks are enclosed within a turbine hall, with a connected control room. Each block has a 55m highchimney to allow for the safe exhaust of combustion gases. Each gas turbine exhaust passesthrough a waste heat recovery boiler.
Natural gas is supplied through a buried pipeline that connects with the national gas transmissionsystem. When the gas supply is interrupted, a back up fuel of low-sulphur gas oil can be used. Gasoil is stored in purpose built secure tanks on site. The tanks are replenished from seagoing tankersusing the nearby River Thames’ jetties.
Cooling of the steam condensers is normally carried out with water drawn from and returned to theRiver Thames through deep tunnels. This “once through” cooling arrangement passes heat to theriver which is quickly dissipated through tidal and other natural actions. An alternative coolingsystem is used when the river water temperature is above 21.5O Celsius, mainly during the summermonths. This alternative system uses evaporative cooling cells that removes heat to the air ratherthan the river but with a detrimental effect on the thermal efficiency of the station.
The principal pollutants emitted are oxides of nitrogen (NOx), which results mainly from the reactionof oxygen and nitrogen from the atmosphere during the combustion process, and carbon monoxide.The back up gas oil fuel has a low sulphur content to minimise releases of sulphur dioxide.
Permit Number RP3133BH Page 22/12/06iii
Emissions of polluting exhaust gases from the chimneys are minimised by the use of dry low NOxburners when using natural gas and water injection when using back up gas oil.
The installation is a lower tier COMAH site and has a Major Accident Prevention Policy that dealsspecifically with major accident hazards and measures to protect the environment.

Schedule 4 – Emissions and monitoring
Note
For the purposes of this Schedule, the following interpretations shall apply:
• For the continuous measurement systems fitted to the LCP release points defined in TableS4.1 the validated hourly and daily averages shall be determined from the measured validhourly average values after having subtracted the value of the 95% confidence interval.
• The 95% confidence interval for nitrogen oxides of a single measured result shall be takento be 20%.
• An invalid hourly average means an hourly average period invalidated due to malfunctionof, or maintenance work being carried out on, the continuous measurement system.However, to allow some discretion for zero and span gas checking, or cleaning (byflushing), an hourly average period will count as valid as long as data has beenaccumulated for at least two thirds of the period (40 minutes). Such discretionary periodsare not to exceed more than 5 in any one 24-hour period unless agreed in writing. Whereplant may be operating for less than the 24-hour period, such discretionary periods are notto exceed more than one quarter of the overall valid hourly average periods unless agreedin writing.
• Any day, in which more than three hourly average values are invalid shall be invalidated.

Subject: Boiler Blowdown
Hi Colin, Just to confirm that as we discussed yesterday we are investigating a possible leak on our main that runs from the blowdown sump to the CW return (emission point W3). We are trying to get a camera along this today to better understand the problem so that we can then decide on an appropriate fix if required. Pressure is not being retained by this line so it is quite possible that this is leaking, but once we find out more we will let you know. If we find this has been leaking, it is only boiler blowdown that this main conveys, so if anything has gone to ground it will be fairly good quality water. In the meantime we are using a diesel pump to transfer blowdown to the discharge point, but this bypasses the meter. The sump is being pumped down between two known levels and records of this kept so that a daily total is still maintained. Over the last three weeks the most blowdown we have discharged in a 24h period was 244m3 against our ELV of 600m3 so I do not envisage us getting close to ELV. Hopefully this temporary arrangement is OK? I'll update you next week once we know more. Thanks, Rod.

INCIDENT ON THE 27TH AUGUST 1995 The above incident involved the overflow of the cooling tower basin and the subsequent release of river water to Dagenham Breach. During the preparation for the flushing sequence it has been found that the dechlorination was taking approximately 20 minutes. The timer for this step was set for 11 minutes, and the last 120 seconds of this time will not allow a hold to be instigated. To allow for a manual check on the chlorine level prior to discharging to the river the operator instigated a hold in the sequence, but this was in the 120 second period. Although the hold had been initiated the sequence did not stop and the flushing gate started to open. Because the manual tests results were not available the flushing gate was selected to manual and closed. On another DCS screen the return gate was closing automatically as part of the sequence, because both gates were closing the tower level started to rise and overflow onto the area around the CW switch room. The water levels were high and the Shift Team Leader was concerned about safety of personnel and further ingress of water into the plant and equipment. Therefore the storm water pumps were run for approximately 10 minutes to drop the level around the site and the building main doors were closed on the turbine hall. Duncan Stewart was then contacted at home and asked if the remaining water could be pumped to the Breach, the Shift Team Leader was informed that it should not. Although the storm water system was full of river water the immediate danger to plant and personnel had passed and a tanker was called in the following morning to pump out the storm water sump and to dump it into the boiler blowdown sump which is pumped into the cooling water outlet bay. ACTIONS 1. The alphanumerics on the flush sequence screen will be discretely labelled to indicate
which timer is running in the sequence 2. Both gates to be placed on the one screen 3. Timer to be extended to match the dechlorination times 4. The tower level alarm to be made a category 1 alarm and the possibility of extra level
transmitters investigated. 5. The sequence to time out and wait for manual intervention before progressing to the
flushing stage.

REPORT ON THE DISCHARGE OF SALINE WATER TO DAGENHAM BREACH. ON THE
27TH AUGUST AT APPROXIMATELY 0200 HRS.
When the power station is operating in the secondary cooling mode Barking Power Station is allowed one hour out of every twenty four to flush the circuit (discharge the contents back to the river) to prevent excessive silting in the river inlet and river outlet piping systems and reduce the build up of the concentration of salts in the system. During secondary cooling, continuous injection of sodium hypochlorite (as a source of chlorine) prevents legionellosis, and reduces the build up of algae in the condenser water circuits. Prior to the flushing sequence, the water is dechlorinated, immediately before releasing it to the river. The cause of the overflow started in the timing of the dechlorination sequence. The final 120 seconds of the sequence timer does not allow any intervention. The sequence was in this 120 second step when the step hold was initiated by the operator. The step hold was initiated to provide the operator sufficient time to double check the total chlorine content of the water prior to discharging. The operator then observed that the culvert gate was opening, and not having had the result of the manual check, the gate was manually closed, via the DCS. On another screen, the return gate was also closing automatically as part of the flushing sequence. Because both gates were closing, the level in the cooling tower basin started to rise and eventually overflow towards the CW switch gear room, and across the site. The Team Leader was concerned for the safety of the operator in the CW switch gear room, and as the water was also running towards the main plant, for the safety of personnel and equipment in that area. The station storm water pumps were switched on and run for approximately 10 minutes to drop the water level and reduce the waters progress into plant and electrical equipment. The pumps were then shut off. This emergency action was followed up by the Team Leader contacting the Environmental Co-ordinator to check that the remaining water could be pumped into the Breach. When he was informed that it could not, alternative arrangements were made. These were to pump the water into tankers and discharge these tankers into the blowdown sump for discharge into the CW outlet bay.
SEQUENCE: The following steps occurred on the 27th of August. 1. 0048 hrs - C.W. Flush group start 2. 0059 hrs - Step hold initiated 3. 0110 hrs - It was observed that the culvert gate was opening. As no report back on the
total chlorine level had been received, this gate was selected to manual and closed. 4. 0116 hrs - Report back on free chlorine received. 5. 0118 hrs - Catchment Level High alarm received 6. 0125 hrs - Cooling tower basin overflowed - Culvert gate opened manually. 7. 0130 hrs - Flushing sequence re-enabled to allow flush to re-commence and to drop the
level in the cooling tower basin. 8. High levels of water on site, storm water pumps run for approximately 10 minutes 9. Remainder of the water was pumped into a tanker and discharged into the blowdown
sump and back to the river. This occurred during the day. 10. At approximately 2000 hrs notification letter sent by fax to NRA following earlier
telephone contact.

EXECUTIVE SUMMARY AND RECOMMENDATIONS :
The ground below the Oil Mist Eliminator Exhaust and adjacent to the GT Distillate fuel skids is becoming contaminated by oil leakage / spillage. The contamination is an IPPC issue and if the contamination is not contained Barking Power Station will not meet the IPPC edict which would result in warnings from the IPPC. This project proposes to contain the oil exhaust / spillage by concreting over said areas thus stopping contamination and making clean-up easier.
PROBLEM DESCRIPTION :
1. The Oil Mist Eliminator exhaust has no containment bund and the oil sprays directly onto the shingle below. The prevention of this contamination is an IPPC edict which if un-resolved could result in warnings from the IPPC. 2. The ground to the west of the GT Distillate fuel skids is becoming contaminated by oil leakage / spillage. The prevention of this contamination is an IPPC edict which if un-resolved could result in warnings from the IPPC.
POTENTIAL SOLUTIONS
Option 1 – Do nothing This is not an option as failing to meet the IPPC requirements would result in warnings from the IPPC and if not acted upon could ultimately lead to the loss of licence to generate power.
Option 2 – Concrete over the areas concerned. Concrete the shingle areas below the Oil Mist Eliminator Exhaust and to the west of the GT Distillate fuel skids thus stopping contamination and making clean-up easier. Cost of this option is £24139.50 and work would take place this financial year.

PROPOSED SOLUTION & WORK SCOPE :
Option 2 – Concrete over the areas concerned. Concrete the shingle areas below the Oil Mist Eliminator Exhaust and to the west of the GT Distillate fuel skids thus stopping contamination and making clean-up easier. Cost of this option is £24139.50 and work would take place this financial year.
JUSTIFICATION
The IPPC edict states that Barking Power Station must prevent oil contaminating the ground in the areas mentioned. Failure to do so would result in warnings from the IPPC and if not acted upon could ultimately result in the loss of licence to generate power.
SCHEDULE
The work would be carried out in this (2007 / 2008) financial year.
RECOMMENDATION
The recommendation is to contain oil leakage / spillage by concreting over the areas mentioned. The total estimated cost is £24139.50 which includes 10% contingency. Once the work is complete the oil will be contained which will adhere to the IPPC instructions. SIGN : J.A.Heslop DATE : 13.2.08
