BASELINE NOISE SURVEY JULY 2019

1.1 Introduction A baseline noise survey was undertaken by Ramboll at the Oikos Storage facility, Canvey Island between 2nd and 10th July 2019. The purpose of the survey was to ascertain if there are any significant changes to the noise climate since the previous ES for the Deepwater Jetty OSL. In addition, a measurement location to the north-west of the site was chosen to capture the baseline road traffic along Haven Road.

1.2 Methodology The survey was carried out in accordance with BS7445-1.

1.2.1 Measurement Locations The measurement locations are shown in Figure 14.1 of the PEIR, denoted by LT1 and LT2. In both cases the noise loggers were attached to the site hoarding at least 2.5m above the ground. In addition, a spot measurement was taken at ST1, adjacent to the football club.

1.2.2 Equipment The following equipment was used for the unattended measurements: • 2 nos. Norsonic 140 sound level analyser (serial nos. 1403396 and 1406951) with pre-

polarised microphones (serial nos. 112825 and 285522 respectively); and • 2 nos. Norsonic 1251 acoustic calibrator (serial nos. 32853 and 34964). The following equipment was used for the attended measurement: • 1 no. Rion NA-28 sound level analyser (serial no. 01070571); and • 1 no. Rion NC-74 acoustic calibrator (serial no. 35125833). The equipment was calibrated before and after use and no significant drift was observed. All equipment owned or hired by Ramboll is subject to regular calibration checks traceable to national standards.

1.2.3 Meteorological Conditions The weather taken from a local weather station (Southend-on-Sea airport) shows that the measurement period was dry with windspeeds predominantly <5m/s. Thus, the measurement period is considered representative.

1.2.4 Noise Climate The noise during setup and collection was observed to be relatively quiet, with traffic along Haven Road the main noise source. During these brief windows no movement in the adjacent car workshop was noted. The week-long measurement period is considered representative of normal operation at the Oikos site.

1.3 Results The key measurement results are given in Table 14.A.1 and Table 14.A.2. The time-histories for the unattended measurements are given in Figures 14.A.2 and 14.A.3 respectively. Table 14.A.1: Attended daytime measurement results

BASELINE NOISE SURVEY JANUARY 2021

1.1 Introduction A baseline noise survey was undertaken by Ramboll north of the Oikos Storage Facility on Roscommon Way, Canvey Island, between 25th and 26th January 2021. The purpose of the survey was to ascertain the existing noise climate at the residential areas closest to the Oikos Storage Facility. In addition, two attended measurement locations further north of the site were chosen to capture the baseline road traffic along Canvey Road. Despite, lockdown restrictions owing to the Covid-19 pandemic during this period, the measured noise levels matched well to the noise levels modelled from the 2019 traffic data.

1.2 Methodology The survey was carried out in accordance with BS 7445-1. Long term noise monitoring was undertaken between 15:30 hours on Monday 25th January 2021 and 15:30 hours on Tuesday 26th January. In addition, two one-hour spot measurements were taken on Monday 25th January.

1.2.1 Measurement Locations The measurement location for the noise survey is shown in Figure 14.1 denoted LT3. The noise logger was attached to wooden fencing adjacent to the north carriageway edge of Roscommon Way, at a height of approximately 2m. Two spot measurements were taken at locations ST2 and ST3 adjacent to Canvey Road, in a layby and the end of a residential cul-de-sac respectively.

1.2.2 Equipment The following equipment was used for the measurements: • Norsonic Nor140 Class 1 sound level analyser (S/N 1403396) with pre-polarised microphone

(S/N 112825) • Norsonic Type 1251 Sound Calibrator (S/N 32853) Calibration of the sound level analyser before and after the measurements exhibited no significant drift. All equipment owned or hired by Ramboll is subject to regular calibration checks traceable to national standards.

1.2.3 Meteorological Conditions Weather data from a local weather station (Southend-on-Sea airport) shows that the measurement period was dry with windspeeds predominantly <5m/s. Thus, the measurement period is considered representative.
