Environmental Monitoring

Air Quality Monitoring

Simultaneous measurements requested by the sanitary authority were conducted at two air quality monitoring plants, classified as monitoring plants with community representation, approved by the Ministerial Regional Secretary of the Los Lagos Region.

Currently, both plants are not active, because their positive results did not justify further measurements in the area. This decision was determined along with the Sanitary Authority of the Los Lagos Region.

Noise Measurement

These noise measurements are performed monthly (subject to generating request) in order to verify compliance according to Supreme Decree N° 146/97 of the Ministry of the General Secretary of the Presidency (MINSEGPRES). The measurements are taking at 5 points, which correspond to the receptors located the closest to noise sources, according to the RCA.

As of June 2014, the new monitoring reports are submitted according to the new environmental standard of Supreme Decree N° 38/11 of the Ministry of Environment of Chile.
