Trl: I. 1 :~: "" November Re: IPPC Licence Reqister Number PO Ref: Annual Noise Assessment - Non compliance. breach in ELV Dear Ms. O'Driscoll, In accordance with the silc license conditions, plrast: see attached the Annual 2017 Noisr Survey. This is in support of the sites notitication of an cxceednact. in ELV relating to noise emissions via telephone communication on the 17{" November. You will nots from the report that whilst the NSL 1 is now compliant, unlortunately, drspiti. cxlcnsive noise reduction mcasures, NSL 2 was in brcach of ttic site ELVs. Noise fcvels wcre of the order of 57dBA to S8dBA Lncq; S3dBA to 54dBA hl) for the daytime periods; SSdBA L,ieq and 5 ldba LAN) for tlie evening period and 52dBA to S3dBA Lhctl and SOdRA to 5 I dra LAW for tlie nigfit time periods. To achieve such a reduction from levels tfiat were historically 58dBA is a signifjcant achievement given that noise is measured via a logarithmic scale. Extensive noise remcdiation works have been complcted which are outlined below, resulting in a cumulative cost ofjust under 350, to the business in terms of continual environmental improvement works, a11 of which is aligned to the sites EL. The cooling tower fan for Niro 2 has been replaced with an acoustically treated cooling tower. One of the criteria for the selection process in terms of noise emissions was to be the Iowest available. The single glazed window unity in the EV-2 building as well as the passive ventilation grilies which are north facing have been sealed up with concretc. These were historically an acoustic weak point in the structure. Previous passive ventilation Tor the purposes of cooling within the EV-2 building has beun replaced by an air handling unit and associated extraction fan. Dairygold Fwd Ingredients Limited.

2 A supply Frin as well as two extract bins have also bccn commissioned lo serve lfic singlc story Silverson Room which is on the Northern fagade of the building. When operating only thc supply fan and one extract fan will operate. These fans are littcd wilh attenualors. A notcworthy point ol' information is that during the sites official opening, weck beginning I Bth Scptcmbcr, several mcrnbers of the residents within the immediate environs were complimentary of silcs works in lcrrns ol' a noticcable reduction of noise at their homes. During the recent Compliance Meeting on November 2"d a request was made for a slatus update in relation to the following Conditions of the license:- 6. I S. 1 Tlic licciiscc shall carry out a noise survey of the site opcrations within six months of cotnpletion of production expansion and thereafter on an annual basis. The survcy programme shall be undertaken in accordance with the methodology spccitied in the 'Cuidancc Note for Noisc: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities (NG4)' as published by tlic Agency The ficenscc shall install noisc attenuation and noise control mcasurcs as outlined in Section 5 and Table 13 of the Noise Zrtipact Assessrtierit Dairygold Expansioii IEL submitted with the licence review application, within six months of completion of production expansion. DFZ Mallow Cornn2ent:- See Section 5 Table 13 of the Noise Impact Assessment Dairygold Expansion EL, Page 4, for a status update. In relation to items listed in Group 1 - some items are not completed to date. During this phase of development and in conjunction with noise data it was decided that the Evapourator 2 windows were a more dominant noise source. Hence, this was prioritised. All ol' these have since been blocked permanently The licensee shaii install noise attenuation on the new dryers prior to operation and within six month of completion of production expansion on the existing Niro Spray dryer The licensee shall implement further noise attenuation and noise control measures, within six months of completion of production expansion, to reduce noise emissions from the CHP safety release valve if lhe steam release activity is to be continued. As you will be aware the planning application, [Planning Registration Reference Number P.D /12 and An Bord Pleanila Reference Number PL was for two dryers. Currently, this planning development in accordance with the planning development details is not currently complete. However, significant noise abatement works were complete as part of this first phase, which is outlined above. Dairygold Food Ingredients Limited.

3 In tcrms of next steps, the site will be completing the following:- 9 Noise profile assessment of thc sitc to ascertain dominant noise sourccs, Givcn thc production planning thc timcline for complction will bc Q1 of Any recommendations of this assessment will be revicwcd with a view to further viable abatemcn 1 projects. Section 5 and Table 13 of the Noise Ivtpact Assessment Dairygold Expansiori IEL will again he an integral part of the assessment process with il view to concluding remedial works in conjunction with additional noise data, and the sites commissioned Acoustic Consultant and Engineer. The site will update its Noise Management Plan accordingly. DFI Mallow will submit any new proposals for approval. Envisaged timehe All the above will be included in the site Environmental Management Plan We hope this meets with your approval as a means forward.
