All vehicles and stationary equipment are powered by fossil fuel engines, which will generate several levels of noise during all phases of the project. Wetland Area Within the Wetland Area a landing stage will be constructed at the Eureka project and at the Tingioloweg. Construction as well as decommissioning will be accompanied by increased noise levels. Noise will be loud when for instance airboats are used. But in the virtual absence of human receptors in swamp area, only a minor negative impact will occur. Operating personnel will obey to standard precautions, Staatsolie General Field Instructions. Transportation of swamp excavators to clear the trails of shrubs will take place at the beginning of the project in this part of the study area. Transportation of people and goods to and from the wetland working sites by airboats and swamp carriers will take place continuously during all phases of the project in this part of the study area. North of the western section of the swamp new houses developments are found. But the houses are far away from the places where the airboats will be used. Yet a moderate negative noise impact from the airboat to the local people is possible due to high noise levels especially during yhe evening. The noise impact from a swamp carrier will be negligible. Noise impacts to humans will have a low frequency because there are few receptors (company personnel will have hearing protection), while noise impacts to animals will also be limited due to their low density. No preventive measures will be required except to keep blasting equipment at a standard distance from inhabitants and preventive measures are recommended, especially for moments of the explosions and of the airboat transportation: Recommended source reduction measures include the following: • Take special precautions when execute explosions • locate the landing stage as far as possible from houses in the area • keep the noise levels of the airboats as low as possible, by o high quality low noise exhaust pipes in best condition o minimum speed, related to water depth and moisture content of “dry” areas o avoid using them in the evening. Impact reduction measures are also relevant or Fauna. Transportation of people to and from the seismic line sites will take place continuously during all phases of the project. Staatsolie by experience takes a certain distance form explosion sites to human beings when executing the explosions. Mitigation measure: limit the use of airboats in the evening.

PESIA Weg naar Zee 2D Seismic 2012 Impact of Noise in lowland area Without Mitigation With Mitigation Dry land Area Magnitude/ Intensity /Size Geographical scale Medium Small Medium term Low Small Medium term Duration Probability Severity Overall significance 71 High medium Moderate Negative Medium Low Minor Negative In the Dry land Area travelling will go along existing roads. Noise levels during transport will have a minor impact being of a moderate magnitude and short-lived, and occurring only twice for a certain location. As acquisition of data takes place in an inhabited area, a potential noise impact could occur during explosions when this would be close to houses. This impact is considered to be minor negative given the moderate noise level, the short duration of the impact and the standard distance to the houses. So preventative measures are proposed and no mitigation is required. Vibration during explosions could cause damage to nearby buildings. Suitable conditions for vibration will be present on certain fine sandy soils with (near-) saturated subsoil. Damage could potentially be such that a moderate negative impact occurs, although this scenario is unlikely. Measures to prevent or mitigate the impacts from vibration include the following: • keep adequate distance from building structures • make assessment of building structures prior to explosions in case nearby explosions cannot be avoided • compensate in case of damage Transportation of people to and from the seismic line sites will take place continuously during all phases of the project. Staatsolie by experience takes a certain distance form explosion sites to human beings when executing the explosions. All noise impacts to the local people are considered to be minor negative at most, because of the relatively low noise levels.
