Growing Season Sample Clauses

Growing Season. Growing Season: The period between April 15 and October 20 of any calendar year. This growing season definition is for determining compliance with mitigation performance standards. It is an average of the growing seasons established by the State and the Counties located within the jurisdictional boundaries of the Chicago District Corps of Engineers. It does not establish the growing season for purposes of wetland delineation. An alternative accepted approach to determine growing season follows: For purposes of this document, the required methodology is to immediately insert a soil thermometer into the wall of a freshly dug soil pit 12 inches (30 cm) below the soil surface. The soil temperature must be documented with a date stamped photograph showing the temperature on the soil thermometer immediately upon removal from the wall of the soil pit. Date stamped photographs of the area surrounding the soil pit where the soil temperature is measured must also be provided. A minimum of one soil temperature measurement per hydrology monitoring well must be collected and provided to the IRT. The growing season is considered to have begun when all soil temperature measurements collected are 41°F (5 °C) or higher. The IRT must be informed at least one week prior to visit made to measure soil temperature so they have the opportunity to be present when soil temperature is measured. The IRT retains the ability to visit the site within 5 business days of the initial visit in order to ensure that the soil temperature remains continuously at or above 41°F (5 °C).
