Section D.3 <br />General Water -Holding <br />I. The following seepage control requirements apply to all rice pesticides having mandatory <br />water -holding requirements such as tbiobencarb, etc. Non-compliance with seepage <br />requirements is considered a water -holding violation. <br />A. Rice pesticides, such as thiobencarb, shall not be applied to rice fields exhibiting visible <br />water seepage that moves offsite into drains that are considered state waters. <br />B. Borders surrounding each rice field shall be compacted before water is allowed to fill the <br />field; the degree of compaction shall be sufficient to prevent water from seeping through <br />the border. For example, compaction may be achieved by driving the tires or tracks of a <br />tractor, or other heavy vehicle, on one side of the border. <br />C. This requirement applies to new or reworked existing borders for the current rice season. <br />D. A common border between two existing rice fields does not need to be compacted. <br />D- l 3 <br />(Rev. 1-10) <br />
