The strategy willensure the control of these species and prevent the spread of them within andoutside the development area. The soil containing these species or parts thereofshall be dealt with as contaminated material and disposed of in accordance withparagraph 8.2 of this Code.ENVIRONMENTAL RESOURCES MANAGEMENTB-46CHILTERN RAILWAYS
