2.11 Noise Pollution at Fjarðaál and in Reyðarfjörður

Indicator 2.11 - Noise Pollution at Fjarðaál and in Reyðarfjörður

2.11 Mælingaskúr í Reyðarfirði


While there are no changes in the operation of the smelter, noise pollution measurements are performed every 8 years.

In 2012 a pot lining factory was built on the Fjarðaál smelter site. Noise monitoring was therefore performed in spring 2012 when the factory was operating.

Next measurement is estimated no later than in 2020.


Results



The figures below show the outcome from 7 monitoring stations in August 2008 and in the spring of 2012. The monitoring stations measure the noise level in chosen spots near the Alcoa Fjarðaál smelter and in Reyðarfjörður fjord.  Objective for the average noise Level is met, and it does not exceed the levels set for this indicator.

In order to monitor whether noise from the smelter is within the set limits, sound levels close to the smelter were measured in August of 2008 and 2012.

Main sources of noise are the unloading equipment at the harbor and the Fume Treatment Plant (FTP), noise was measured while the unloading equipment was on. Noise levels were measured in 7 places in Reyðarfjördur: 4 places by the border of the smelter site, by the farm of Hólmar, in the town of Reyðarfjördur, and south of the fjord facing the smelter site (Figure 4).

The maximum level set for the site border is 70 dB(A) and all results were below that limit.

Metrics, Targets & Monitoring Protocol



Metrics: What is measured?


  1. Average Noise Level (DnL) at established monitoring stations at the smelter site. (Project effect: direct).
  2. Average noise level at established monitoring stations in Reydarfjörður. (Project effect: indirect)


Targets


  1. Day/Evening/Night Noise Levels (db(A)): 
    1. Smelter: 70/70/70 
    2. Light Industry/Dwellings: 55/50/40 
    3. Dwellings Only: 50/45/40 
    4. Summer House: 40/35/35
  1. Construction: Less than or equal to 65 db(A) Operation: Less than or equal to 55 db(A)

Monitoring Protocol

  1. Continuous noise monitor will record data for specified intervals. Data is collected monthly to decide the baseline and thereafter each time the noise level is expected to change.

Rationale for Indicator Selection


Ambient noise levels influence the quality of life in a community. The presence of consistent, loud noise detracts from the appeal of an area and may be detrimental to the long-term sustainability of the community.

Local community residents are concerned that the Fjardaal smelter near Reydarfjordur could have a negative effect on noise levels in the village.

Noise levels will be driven primarily by the transportation of materials, equipment, and personnel to the plant, as well as plant operations.
